450C Air Compressor Kit by Viair - 45040

Jonathan Ivins: First impression after install is very good. The quality looks really good for the price. Used this to replace a vixen pump that was nothing but trouble. This one is much quieter, better built, and pumps a lot faster. Will update after a week or so of use.

Update: it's been 4 weeks, since install ive had zero issues. Testing shows it fills roughly 3 times faster than vixen and only runs around 2 minutes to regulate 115psi to 140psi on my 7 gallon tank. Very impressed and will recommend.

philip: The compressor is fairly quiet. I thought it would fill up my air rite suspension a little faster but overall I am satisfied

Brent T: Edit: desert season started and I was finally able to use this on my truck. Aired down and back up twice on 4 265/75/r16's and it worked great. Definitely heat up though! Enough to burn my hand if I touched it for more than a second, but it never shut down so it was clearly functioning as it was designed. Took about 1 minite to air up from 20psi back to 32psi. Word of advice though... if you're not going to hook this up to a tank, I'd suggest adding a mechanical relief valve to your air line because this thing will run until it irreperably destroys itself if you set it up in such a way that it isn't constantly open (which I'd like to stress would be a failure of the person who installed it and not the actual product)

-----------------------------

Desert season hasn't started yet, so I'll have to come back and amend this review when I use it to air my actual truck tires back up from a target 20psi, but have had the opportunity to use it in a few cases.

1. Bicycle tires air up great.
2. Aired up my friend's truck tires as they were a little low.
3. Have used it to air up a vessel I made for pressurized camp water.

All three...

Travis: Working great so far. Installed on back side of my truck above my spare tire with the VIAIR mounting bracket. Been on truck for a good long time now and no issues.
2023 update. Been using on and off since purchase and no issues filling up my 5 gallon air tank and filling tires or using any random air accessories. Using remote mount for the air filter to keep out potential water ingestion. It's been through water, mud, dirt, and sand all these years and still works fine.

aeleiram: Easy to install, and works great! It is used on the air suspension on my Ford F-550, which I use for my tree business. It's been on the truck for about 4-5 days, and it works just like the last one we had - exact same model. The last one burned out running when there was a fault in the line that wasn't identified properly. This is s great little compressor and holds up the suspension well under several tons of rock, dirt, and wood chips.
