The Polar Air Difference:

Polar air by Eaton Compressor has defined three goals intended to make us the most successful 10 hp air compressor manufacturer in the industry, Premium quality products, Best warranty and highest customer satisfaction! We know that there is only one way to reach our goals, by doing things right! We use only the best Brand name components to manufacture our products. Our 10 hp air compressor Rotary screws have the newest and greatest technology in the compressor industry. The Polar Air by Eaton Compressor 3rd Generation rotary screw units have top shelf brand name components with NO china parts! These Top brand suppliers have been in business for many years and provide only the best quality and energy efficiency, parts/service will give the best all around support for our customers.Our, best in the compressor industry warranty reflects our units quality with no tricks or deception. We offer NO generic parts. These top brand parts suppliers come at a higher cost to our company 30% more then the cheaper generic brands. We would rather use the best brand parts and pay a little more upfront, then have a dissatisfied customer down the road with parts availability and quality. Our shopping customers ask how do you compare against brand X....? we think we are better in a lot of ways. Our screw pumps, electric motors, magnetic contactors and filters are none proprietary to our brand. This gives the customer a fair option. Proprietary parts is another way to rip off the customer. We have seen PLC's cost $3,000 on a $5,000 compressor. This same comparable PLC through our company is $750. We have seen motors from other big brands made proprietary to their design purposely costing 500% more than our motor. We have seen magnetic contactor's from our competitors with special part numbers costing 500% more. We have seen the screw compressor pumps from the competitor that are proprietary to their design costing 500% more. Save yourself from being ripped off when quoting your next compressor, be sure to get a quote from them on the compressor and main replacement parts and compare. Ask the replacement cost for the screw, electric motor, filters, cooling radiator and fan. We encourage you to compare so Let us share with you why we are the best!

The Heart of your Rotary Screw:

The Airend is the most important part of your compressor, it is the heart of the machine that actually compresses the air. That is why here at, Polar Compressor by Eaton Compressor we use only the best German and Finland name brand airends. The German made EVO Rotocomp  have been producing these airends for over 65 years. Our Finland made G.D airends have been around since the early 1900'S. Most airends are only good for up to 40,000 hours and then they need a complete overhaul, with our airends they are good for  70,000 running hours as long as the unit is maintenance routinely and the correct oil is used. Polar Air Gives you a 10 year warranty on all their airends!

All Polar Air Rotary Screw air compressors are equipped with these state of the art screw airend compressors manufactured in Germany and Finland. These airends have precision-aligned back to back tapped roller bearings with close tolerances guarantee long life cycles and out standing reliability. Each air end is tested to meet consistent high quality standards.

These airends use the highest quality duplex tapered roller bearings which extend the life time by double over the ball bearings design. These airends were designed with two separate bearings one to take the axial load and the other takes the radial loads. So even in the most severe conditions it gives longer bearing life to the airend.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         These State of the art airends air cooled by a flood of injected oil. The oil injection sprays directly onto the rotors and roller bearings,

this helps efficiently cool the compressor. The oil helps to seal any gaps or clearances between the rotors and the housing. It works

in the way of not allowing air to flow back the wrong way thus lowering your air ends efficiency and performance

Premium Industrial Air Dryers

This package includes our Industrial 58 CFM energy efficient air dryer. Our Polar Air dryer is the only energy efficient dryer system with aluminum refrigerated air inner cooler. The air is filtered of all solid particles 0.01 micron and larger. Clean, dry compressed air leaving the dryer minimizes maintenance and repair and also reduces internal dryer contamination. We designed them with non-corrosive inner and after cooler. Our dryers feature stainless steel heat ex changer, Auto drain, gauge to monitor refrigerant pressure, Outlet baffle heater to prevent condensation on the outlet, environmentally friendly 134A refrigerant, and a built in coalescing filter. These dryers carry a 10 Year warranty on the heat Ex changer and 2 year on the components.

Receiving Tank

These units come with 120 gallon vertical painted receiving equipped with Hydraulic hoses and fittings. The dryer mounts right on top of the tank for setting on top of angled iron designed to take up less space.

These tanks are made in the USA  and have ring based design to prevent cracking, Standard NPT ports, ASME, NBBI, & CRN approvals, they are rated up to 450 degrees F, and they are coated with anti corrosive/ rust prevention blended steel to increase the tanks life. 

Premium Industrial Motors

We use only premium industrial name brand motors to run our compressors. Polar air uses only low 1750 RPM motors. We have chosen motors that come with the best certificates and quality assurances so we know that you are getting the best as well! We use High Efficiency inventer variable speed duty motors constructed with superior materials, higher service factors, longer bearing lives, lower waste- heat output and less vibration. We also pass the motor warranty on to you for a full 5 year on single phase and a full 10 year on 3 phase!!

The Hyundai motors are made of heavy duty cast iron construction. Hyundai motor Company has been around since 1967. We use TEFC (Total enclosed fan cooled ) , meaning the motor is dust tight and doesn't allow outside air in, it instead uses the fan to blow air over the frame of the motor to cool it. These motors all have copper bar rotors, this technology dates back to the 1920's. Copper helps improve the electrical energy efficiency of the motor because of its density and ability to transfer energy. Many motors are made of aluminum rotors, these inefficient electric motors waste electrical energy and therefore cost more to operate. Copper reduces the energy loss by 15-20% compared to aluminum. Inefficient motors case many issues, they waste more energy, in turn increasing electrical demand,, thus increasing your electrical cost. Copper generates less heat and thermal stress therefore enabling longer life to the motor then aluminum.

Save that energy!!

Since the motors consume a majority of the energy produced then the controls you put on the motor become an increase importance. When a motor starts at full load voltage it causes a voltage sag on the power system, it can cause shock damage creating long term damage to your motor. You can save 25-70% on energy by using motor controls or variable frequency drives. Our entire rotary screw line has the ability to have variable frequency drives installed in them. We use Schneider Altivar71 Brand drives that carry a 5 year warranty. Schneider Electric has been around since 1981.What's the benefit you might ask? Lets break it down.


When a motor is started it takes as much as 8 times the full load motor current to start. An adjustable speed drive can take on 50-70% of that motor full load current by starting the motor at zero frequency and voltage, it works by magnetizing the motor winding's and builds the frequency and voltage slowly, in short the variable speed drive starts as a zero speed and accelerates smoothly up to your settings.Programmable controls allow for adjustable operating speeds as well. These  Schneider Altivar71 variable speed drives can be programmed to run at specific speeds, to stop at a specific position, they are even capable of applying a specific amount of torque. The ability to control these minimizes mechanical and electrical stress on the entire unit.

Lower Power Demand:

Many power companies will offer rebates when running your system with a variable speed drive. in most cases the system will pay for its self over time, even in as in short of time as one year. Because some power companies are limited then they put demand factors on industrial customers, so they charge you for surges in your power that may be robbing other customers during peak hours.  The variable speed drive eliminates  those surges. We have provided you with an example of ht average energy savings from APE Energy. use the link to see the potential savings. When 60 cycles of electricity are inducted into the electric motor, the motor RPM is a low 1750, however the Variable speed inverted drive will change the 60HZ to 60 Cycles of electricity from 60 cycles down to 18 cycles, depending on the pressure, The whole ides of energy savings with this unit is to lower the cycles, the lower the amp draw coming from your electric motor.The electricity amp draw that an electric motor is using determines what your electric bill is, so the lower the amp draw the lower your bill will be!

VMC Inlet Valve

  As mention earlier the airend is the heart of the compressor but is does not work alone. The outside air is brought in and filtered before it hits the inlet valve to insure it is receiving clean air.  The inlet valve regulates the amount of air that is sucked in by the rotary screw. When the valve is in a "loaded state it is compressing air and pumping it into the airend, when it is in an "unloaded" state is shuts off the air supply, so the motor and screw air turning but not taking in air. Therefore not pumping any air to the system. Our VMC inlet valves have a counter weight which insures fast, tight closer when the air flow is reversed. This load and unload system has greater energy savings as well. When running the compressor in unloaded state it allows the compressor to store more air then is being used., a storage tank must be used in this case.  The larger the the storage tank the longer the the no load cycle time, the greater the savings. This unis will save you hundreds on your electric bill because under start up the modulator valve is completely closed. This closes the air off to the screw intake making low load under start up. After the unit gets started, it has a 12-secound time delay. this allows the unit to get running fro 12 seconds before it starts pumping air. This makes no load starting and will save your magnetic starter contractor and motor because of low amp draw.  VMC was established in the 1970's      

Programmable Logistic Controller    

10hp air compressor by Eaton Compressor is controlled by a user friendly Logika PLC (Programmable Logistic Controller). This controller makes this unit bullet proof. These controllers have may many features that are extremely user friendly and easy to use. Here are some of its key features.

    variable speed ready to Control the speed of the motor

    Adjust Pressure - to what pressure range you need. This can be set by the customer, this unit has a shutdown in case the unit goes over pressure. the unit has a maximum pressure setting - the computer will sense that it is going over pressure and will shut down.

    Low Oil Shutdown - if the controller senses that the unit is going into high temperature it will shut it down. It will also shut down if the compressor runs low on oil.

    Reverse Fault - the controller will control when the unit is wired up if it is running backwards, it will sense a reverse rotation fault and shut the unit down

    High Voltage Fault - if the voltage is 15% over the power supply voltage rated on the Polar compressor data plate, the unit will shut down. Also if the voltage is 15% under it will shut is down as well.

    Over AMP Shut down - if the motor is pulling to many amps it will shut down. You can check the amp draw of the electric motor as it is running and also on the exhaust fan motor

    Clock and Date - Built in Clock and Date to help keep track of preventative maintenance services.

    Light - Has a built in light for dark locations.

    Parameters- has a maintenance parameter system to create and maintain the parameter and control information.

    Hour meter - Built in hour meter to keep track of the running hour on the machine.

    Fault History -The PLC stores history if the unit shuts down, information on why it shut down is stored

    Maintenance Service - Keeps track of when to change the air filter, oil filter and the coalescing filter along with the unit needs greased. When they need changed the PLC will sound an alarm.After changing you simply reset that filter back to zero and start the maintenance tracker again.

    Air Differential Control- with differential control you have a wide range of pressure settings. You can take the kick-in pressure all the way down to 100 PSI and all the way up to 145 PSI. You can adjust this range anywhere in between. You can also set the high end down to a lower pressure where ever the customer unit pressure is desired. The Polar Compressor is factory set at 120 kick in and 145 kick out. The lower the pressure the higher CFM and the more hours you will get on your screw compressor, so keep the pressure as low as possible.

    Built in Timer -will sense when the unit is not being used for a period of 20 minutes under no load, this will shut down the machine automatically so it will restart as air pressure goes down to the kick- in set point.

    On- line demand - this setting is made for high volume and will bypass the automatic kick-off mode. It allows the unit to keep running on continuous run mode for high air demand.

    Warranty - These PLC's carry a 5 year warranty

    Daily / weekly Schedule - This unit can be programmed to start in the morning, can shuts its self at lunch if needed and can turn itself in the even as well, or when ever needed.

    Self Start - if the power is lost this unit will automatically restart itself, this eliminates a maintenance crew to have to restart after the shut down.

    Master Slave - this controller can switch from one unit to the other and maintain the same use of hours, it can adjust the pressure to be the lead or the lag unit.


     Premium Mann Filters

    Filters help protect the compressor from wear and damage. It is the most inexpensive way to prevent possible costly repairs. It is vital that these filters are replaced and inspected on a routine basis, the timing is important as is reduces the chances of component and airend contamination. It can decrease the energy efficiency of your machine as well if not done.  Because we know the importance we use only genuine Mann Filters. These Filters are not exclusive to us therefore after your warranty is up you will still be able to find these parts. Mann Filters are made with exceptional quality and provide optimum protection against harmful elements. Our rotary's also have Pre-Filtration on the outside of the cabinets. Although this is an upgraded feature it is one that is well worth the cost to protect the life of your compressor. Even in environments that are not that dirty the build up over time can be damaging to the system and seriously impact the performance. ask about adding a Pre-filter kit to your system to save even more money!                     


    When it comes to the smaller parts of our units we don't spare on quality neither.  For Our electrical components are French made Telemecanique, they are also UL/CSA compliant. We use High quality brass valves. We use V-Belts from top name brands that are rated for 25,000 hour life expectancy. The Rotary screw cabinet is made with heavy metal construction with easy latch doors that contain sound proof material for ultra quiet operation.
