The Difference

Polar Compressor delivers overwhelming performance to ensure that they meet the needs of the most demanding environments. Our pumps require less maintenance, service and downtime than any other compressors in the air industry's. All products are designed with exacting tolerance and specifications to deliver all the power that is needed at the job site, garage or shop. Polar air industrial duty gas driven air compressor series is number one in its class! These units are powered by one of the best name brand gasoline engines on the market, Honda GX series! our full cast iron 2 stage compressor pumps are designed for longevity and power! The gas driven compressor comes with a 5 gallon mounted gas tank. All this is mounted on a 30 gallon power coated ASME certified air receiver. And best yet our compressor are backed by a 5 year bumper to bumper warranty! The Honda engine carriers a 3 year manufacture warranty as well.

High Performance design Pump

We have designed our pumps to out last them all! We want to give you reliability no matter what job you are doing. we have designed our pumps with ALL cast iron! It has solid cast iron cylinder, cylinder heads, crankcase flywheel , crank and forged steel connecting rods - not aluminum! 99% of the pumps you see on tthe market today have aluminum rods. Heat can be your pumps worst enemy so we have designed our unites with raised platforms to pull air under the pump to help cool the compressor. The V style shape of this pump also serves a purpose in that it helps eliminate hot spots and gives consistent cooling. Remember a cooler pump means a longer life.

This pump has large Timken-Style roller bearing on the crank ends on each end of the crankshaft.  This ensures good crank stability and long compressor bearing life.  Each cylinder is all cast iron with no sleeves or aluminum.  All cast iron prevents cylinder distortion and egg-shaped cylinders when pump gets hot.  This pump has 2 B-Section belt drive.  Many of the pumps you see on the market have one belt…this is twin belt.  Twin belt ensures better belt gripage and longer belt life.  This pump has head unloaders.  This is very nice for continuous run applications such as gasoline driven or electric driven high duty cycle applications.  Head unloaders are an air cylinder in each head.  When air is applied to them, they open or push the intake valves open allowing the pump to go into a free wheel mode.  The cylinders are still moving in a free wheel mode, but it cannot compress the air because the intake valve is held open.  This pulls cool air into the cylinder.  The cool air absorbs the heat in the pump and blows it back out the intake valve.  This is nice when you are sandblasting, etc., under heavy duty cycles.  This pump has a site glass to view your oil level.

Some of the competitions RPM's are almost 1/2 or double the RPM of our pump because they are much smaller and have to run fast to produce the air. This pump has 1- piece connecting rod ( all STEEL...not aluminum ) with a re-build able rod-to-crank bearing insert. This pump has valves intake and exhaust that are concentric ring valves or disk valves. These valves can be taken our of the head without touching a head gasket. They are sealed by an O-ring. It does not have reed valve system - disk valves are a much better valve design. Disk valves have been in quality compressors for over 100 years. This pump has intercooler and aftercooler lines. The intercoler cools the air between stages and after cooler cools the air after it comes out of the 2nd stage. 


Polar air only uses high quality, high performance components to build their compressors. So when it came to choosing what was going to power our gas driven compressors there was no better choice then Honda GX Series! The Honda GX V Twin engines have higher horsepower, quiet operation and greater fuel efficiency along with easy operation.

The V twin engine is designed to allow more air flow and better cooling. More cooling means better combustion as well, which means more power! Since Honda has put the two together you get greater durability, which means longer life for you compressor!. The 5 Gallon gas tank that we have mounted to the tank is EPA approved and certified, our 5 gallon tank allows for longer work time in between fills.

The Honda GX engine is __ Super Smooth running! These engines have many features like Electric start, slant cylinder design for smoother motor operation, muffler has spark arrester and ensures super quiet operation, overhead valve design, hydraulic valve lifters, low oil shut down, automatic engine decompression release for easy starting, key switch and battery charger.This engine also has electronic ignition - no points to fool with. The engine also has an engine idle-down when unit is in free wheel mode. in cold weather or warm it doesn't matter this engine can handle it. Honda gives this engine a 3 year warranty that we pass on to you.  

The Set Up

This unit has a 30 gallon ASME approved air receiver. We have customized it by using fabricating a stand for the engine. This Braces the platform of the tank and makes tightening your belts easier. By using the platform under the engine this unit is super smooth without little vibration. The unit runs as smooth as one of our electric driven pistons with the exception of the noise from the Honda engine. The air receiver has a manual drain 1/4" ball valve that is accessible from the front bottom of the tank for easy draining. We use a quality tank gauge and all safety and pop off valves are ASME approved. The unit has a 3/4" Ball valve air outlet.  Our Belt guard is custom built here in our factory. It is Heavy Duty - 13 gauge expanded metal. This allows for quite operation due to low vibration. The unit requires a 12 Volt battery and 2 battery cables to run, these are not included. Set this unit up in your service truck and your ready to work!

The BEST warranty around!

Polar air backs all their compressors with the best warranty in the industry, and we are not kidding we did the homework! We have provided you with that warranty comparison as well. Polar air gives you a 5 year Bumper to Bumper warranty ( the Honda engine is 3 years manufacturer ) . This warranty is NOT a limited or pro-rated. Make sure you research and ask questions when warranty comparing. Be sure when you buy that you are buying a FULL warranty. Just remember, a pro-rated warranty means that the older your compressor gets within the warranty period the more risk you are in, the percentage if higher that you pay out of your pocket. With our warranty we don't ask you to buy a service plan or extended warranty, we only ask that you purchase your oil through us. This ensures that the correct oil with the specs needed to run our pumps is used. Our trained service and support team is ready if you may ever need them and we carry a full line of new replacement parts.
