This is our 3-Cylinder Heavy Industrial air compressor pump with 18 CFM Displacement and a Free Air (usable air) of 14 CFM @ 90 PSI.  Don't be tricked by air compressor dealers giving you CFM Displacement and you think you are getting the Free Air...and you are really not.  For instance, this pump has 18 CFM Displacement.  I have seen companies advertise this as "18 CFM @ 125 PSI"--this is not true!  Displacement is the bore of the cylinder times the distance in the piston stroke times the RPM at zero pressure, but as you go up in pressure, you will lose efficiency on your pump.  The CFM will diminish from 18 to 14 @ 90 PSI.  We give you the "Free Air" @ Pressure and the CFM Displacement--NO TRICKS!!!  This pump has a maximum PSI of 135.  There are companies also advertising this as up to a 7 HP--this is BULL!  They are giving you the "Peak" Horsepower when it really takes half the horsepower they advertise to pull it at maximum RPM.  By doing this, you have been tricked and think you are getting a 7 HP, but you are really getting a 4.5 HP pump--THE TRUTH!  Our name for our HP is the "TRUTH HP".   To gauge your motor HP, check the amperage on 220V.  It takes 19.5 amps (running amps) to pull this pump @ maximum RPM. However, a 15-amp motor on 220V will pull this pump but not under extreme duty cycles.  For extreme duty cycles, I would recommend a 4.5 HP, 19.5 amp or more.  Any amperage under this is not big enough.  This pump can be slowed down by putting a smaller pulley on your motor and it can be ran with a 3 HP motor pulling 15 amps on 220V (running amps).  Please note:  DO NOT go by the HP being advertised on most compressors because your motor will not be big enough to pull your pump.  This pump will run your DA Sander and many of your air tools in your shop.  I have also seen it run sandblasters, but you must size your nozzle on your sandblaster to the CFM Free Air of this pump.  If you size your nozzle too big, you will be over the CFM the pump puts out and it will not keep up.  This pump is SUPER QUIET!  You will not believe how quiet.  It is so quiet you can stand 5 feet from it and easily talk on the phone - AWESOME!!!  The dimensions of this pump are: 18" W x 13.5" D x 14.5" H and Flywheel is 10.5". Minimum RPM is 600 and a maximum RPM of 1080. The bare pump weighs 60 lbs.   This pump has all cast iron head, crankcase, crankshaft, flywheel, cylinders, and valve plates. This pump runs at a SUPER, SUPER quiet 73 dba. This pump is not only quiet, it is not like the cheap pumps on the market. This pump is very durable and has 360 degree cooling around each cylinder. In a single-stage, 3-Cylinder design, you get maximum cooling around each cylinder. On the other in-line pumps, one piston behind the other, they do not cool as well as the 3-Cylinder pump. The reason for this is that the flywheel has a fan built into it. It blows air across the cylinders to help cool the pump, but the in-line pump has one cylinder behind the other and the back cylinder does not get air. This makes your pump run much hotter in heavy industrial applications. This valve system is still great quality. We recommend cast iron cylinders and valve plates for maximum durability and pump life. We have thousands of these pumps across the compressor market over our 26 years of being in business. We have NEVER had a pump warranty as far as valve failure, cylinder failure, or crankcase failure. To do this, you must run the pump at the pump speed we recommend and do not go over the pump speed or your pump will not last.---Just remember...SPEED KILLS!!!  It will make your pump run hot, your valves will not perform as well, and your pump will run noisy. For example, if your family car will go 140 miles an hour and you run it 140 miles an hour? how long will it last???  NOT VERY LONG!- this is the same principle in an air compressor pump - - if you run it at a lower RPM, it will last for years and years and years! The advantage of buying a pump here at our factory is we can give you technical advise and a complete parts inventory in stock-at a reasonable price. This pump includes:

  • Pump has a V-Style, Double A Belt Flywheel included on pump (10.5" in diameter)
  • V-Style Cylinders for maximum cooling
  • Solid cast-iron head, cylinders, crankcase, flywheel, crankshaft, and valve plates
  • Large Steel Automotive-Type Filters - not plastic
  • Large site glass for viewing your oil level
  • Head Unloaders for continuous run use and in gasoline driven use

We can ship UPS !!!  Check with us before ordering for an exact freight quote.  This is the largest pump we can ship UPS to be safe without any damages.  This unit is very well packed to survive the rough transit from UPS.  Our goal is to get you a great quality compressor at the best way of shipping at a reasonable price. **PLEASE NOTE: When sending in payment for compressor, please include the following information with payment: Name, Business Name (if applicable), ship-to address, itemized list of what you have paid for (description of unit with amount, freight and additional services (if applicable). This helps our accounting department and ensures the correct unit is shipped since many are being shipped daily.** We accept money orders, certified checks, and business checks and personal checks. However, if paying by business or personal check, unit will ship 10 days after receipt of check. If you have any questions please feel free to call us  @ 877-283-7614. This unit's warranty is for parts for 5 years. The advantage of buying from our company is that you are in direct contact with the factory who knows air compressors (because WE build them). The problem from buying from most dealers is that they do not even know how the compressor operates or how to fix it. This unit's warranty is covered by our 24-hour, 7 days/week here at the factory. If you would have a warranty issue, someone is here to take your call anytime of the day or night (not an answering service) and stock all warranty parts for this unit. Most dealers do not stock all parts for their unit. They have to order it. This makes downtime for you, the customer, that you do not need. We hardly ever see a warranty. We have the best warranty in the business because of the quality and pride put into our unit. Thanks for taking the time to view our products.
