Customer Questions & Answers

Is it 1.8 hp or 1.6 and 5 CFM @90 or 5.2 @90

The picture shows its is 1.8 hp and 5.2 CFM @ 90 PSI but the specs show 1.6 hp and 5. CFM @ 90 PSI which one is correct?
Asked by: bdwayneh
It is 1.6 horsepower with a 4.5 gallon hotdog tank. It was $349. Well worth the money.

Has anyone else had the air pressure regulator go out on this compressor? Happened to me and several contractor friends

Asked by: nick
Have had this with a couple before I figured it out. Drain the tank before setting it upright. Water goes in the manifold otherwise and then in winter will freeze in the regulator. You can get a rebuild kit online from ereplacement for about $15. Mfg. only sells the whole manifold. I also have just put a new regulator bought from amazon on one since I only use one connection anyway and that is mounted to prevent the water problem.

Can this compressor be ran upright(storage position), as well as laid down or can it only be ran while it's laid down?

Asked by: Brian
It'll function in both positions but is not recommended to function in upright storage position and would risk in damage in low oil lubrication to cylinder.

What is the temperature rating to start and run the compressor?

I'd like to use the compressor outdoors in cold conditions (below freezing), will this compressor work? Is there a simple way to ensure it stays warm enough to operate?
Asked by: Hilo
In my experience, the compressor has a really hard time keeping up when it is below 35 degrees ambient temp. I was on a cold jobsite and couldn't get above 100psi

4.5 Gal. Portable Electric Air Compressor is rated 4.4 out of 5 by 68.
Rated 5 out of 5 by from Wow air compressor! Before and after I have to turn the valve open then turn on the compressor for a quick squirt of any possible contaminants. I am using 800 foot LBS impact wrenches, air ratchets, air grinders, air jack hammer, nailers and using this compressor for inflating tires, and still runs good and no problem. Don't forget to purge the air tank regularly.

Rated 2 out of 5 by from hope to find a better one i run a small construction company. and try to own 2-4 of every tool we use on a regular basis. so i own a few compressors. i bought this style about 2 years ago and was at first very happy. it had good wheels, was heavy but portable. and could run 2 roofing guns it never shut off but it could run them. it was about 5 months then the thing popped one day and never worked again. had an extended warranty and exchanged it. three days later the wheels flew off new one i slapped them back on but never was quite right. then another month the regulator leaked so i took it back again and grab the third one. all on my extended warranty. about 9 months went by and the thing stopped making air ran like nearly normal loud as could be but never built pressure. i was about to take it back a 4th time and demand money back but it was stole by evil thieves before i got around to it instead. thank you insurance. over all i think it could be a decent product i know a few other companies that own one and use it like all is great. but 70% of what they use is battery power nailers. if you need something for light regular use it can work. heavy use it's a be sure to buy the extended warranty you will need it
