•Precision Built German Bauer/RotorComp Over-sized pump (since 1934) 10-year warranty•US Motor Corp Y/Delta NEMA American Standard Inverter duty TEFC Premium Efficiency motor... USA standard UL/CSA Listed ( Since 1960)- 10-year warranty
Tolerances and Rotor Profile Designs. Components used to produce a rotary screw compressor pump are very important in regards to true energy savings. Rotorcomp -EVO02 Male/Female Rotors and Cylinder Cases are machined to highest precision tolerances. These high tolerance standards reduce internal pump leak paths and yield high scfm performance. A lot of foreign rotary screw compressors talk a big game but cannot meet the precision tolerance standards in their rotary compressor performance. This is because of outdated antiquated machinery and outdated compressor designs. Rotorcomp patented rotor designs yield the highest performance in KW to CFM output performance. Making pumps with high-efficiency standard’s costs a lot more to produce in time and labor costs. Rotorcomp Germany is a top 5 world compressor component manufacturer with over 60 years of know-how experience in the compressor industry. They are continuously increasing performance, staying ahead of the competition and saving energy.
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 inverter 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 US Motor Corp Motors are made of heavy duty cast iron construction. 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 cause 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.
This package includes our Industrial 30 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.
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.
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 ensure 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 ensures fast, tight close when the air flow is reversed. This load and unload system has greater energy savings as well. When running the compressor in the unloaded state it allows the compressor to store more air than is being used., a storage tank must be used in this case. The larger the storage tank the longer the no load cycle time, the greater the savings. This unit 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.
7.5hp 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.
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 rotarys also havead 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!
