About Compressor Duty Cycle
Compressor duty cycle refers to amount of time a compressor can be operated in a given time period, at 100 PSI and at a standard ambient temperature of 72°F. Duty Cycle is commonly expressed in percentile as: compressor on time (compressor on time + off time) %. As an example, a compressor that is rated for 25% duty cycle means that compressor can be operated at: 100 PSI @ 72°F for 10 minutes on and 30 minutes off. 10 min. on / (10 min. on + 30 Min. off) = 10 min. / 40 Min = 25% duty cycle.

compact, very strong magnets in motor, can be felt outside case with steel bar, compressor seems like it is well made, even being an offshore import. i've had these two pumps in service for a month and they sound good and pumps well, will update in another 6 months if still no problem.
looks like this compressor could be mounted out in the elements as long as the intake port was piped to a clean location, i typically pipe these to the truck cab so it takes in cleaner and already partially dehumidized ( air conditioned) air.

I use it as a straight air source, meaning that I don't run a pressure switch or air tank with it. I got it primarily because I was sick and tired of trying to save a buck and buying the el cheapo units from Harbor Freight and having them zonk out on me or overheat after filling just one tire.

I am using this unit for filling my 35" tires when off roading. I air down to about 15 psi when off roading and then inflate back up to 40 lbs. This unit takes around 4 to 5 minutes per tire. Not the greatest but not bad. Having it run continuous without stopping is KEY! If 5 minutes seems long (20 minutes overall) then just try a cheap unit that fills one tire and takes 30 minutes to cool down and turn on again... Yowzaaa! What a friggin aggrivation!!

In a strange twist of irony, I actually hacked one of my cheapo units from Harbor Freight and used the end cap portion that has the on/off switch and fuse. It was simply a matter of splicing the wires and connecting straight to the battery. Done and done. The cap was roughly the same size but not a perfect fit however it was nothing that a bit of high temp JB Weld putty couldn't solve.

At the end of the day I am very happy with this unit. Works like a charm. Did I mention this thing is quiet? Very quiet! I have it mounted right behind the front grill of my Jeep Wrangler. I ran the air filter up into the engine bay. See attached pics..

I'm very pleased with the unit's performance and the fact it is rebuildable, though in my usage I don't forsee that need. I wish I could have had a faster shipping option because this was used on a Handi-cap van.

I have used this compressor without trouble and it exceeds the requirements I needed for driving a pressure driven centrifuge for turning waste oil into diesel fuel.

Durable compressor with extended run time. With a 2.5 gallon tank, this unit is adequate for filling 33" tires in a reasonable amount of time. The CFM is a bit low on this compressor, so filling more than 4 tires or tires larger than 33s takes a bit of time.

Long term, this compressor will probably be demoted to another vehicle to power an air horn while I search for a higher flow-rate compressor.

The compressor I had Prior to this was a piece of junk, but the Viar 450C is simply amazing. It airs in a quarter of the time as my previous compressor. HIGHLY recommend this product.
