Viair 450P-RVS (Class A Motorhome)

Bought the unit for my 5Th wheel and for my truck. I lower the tire pressure on my truck to 35 PSI from 70 PSI to go out on the sand dunes for fishing. When I do have to top the tires of again, it takes time. Especially when your doing all four tires, but it does work.

I love using my VIAIR. Easy to use, and can air my big Class A tires right up.

I ordered my compressor on Jan 22 received it on Jan 23. I do within a few hundred miles of Techno RV. You can't ask for better shipping. I have used my compressor several times very impressed with the quality. I would recommend this product to anyone.

This compressor is a well made product. It has everything you need for full operation anywhere you may need to use it. It does everything it is advertised to do. The included air hoses will reach all tires without the need to move the compressor.

I stumbled onto a video produced by TechnoRV about Viair compressors. They eliminated all the ambiguity from the various sites trying to sell their, in some cases outdated, inventory. TechnoRV explained which each model (RV specific) was intended for and addressed all the accessories of each model. They also stated that any model ordered would be the most current version of that Viair model. No obsolete products! Additionally, their price was competitive with all the “big on-line” names. I will look to TechnoRV the next time I determine the need for a product for my Class A motor home.

Going to roll fulltime in a Class A motorhome. Needed something better than my old 6 gallon pancake compressor & bucket of hoses. Purchased the Viair 450 RVS to easily push 120psi into the tires. The unit is lighter, clips to either the RV or Jeep battery with enough coiled tubing to reach each tire. Planning to add the digital readout pistol to the arsenal in the future. Will check with TechnoRV at that time. Great product.

I bought this to fill tires on a 40 foot diesel pusher with large tires. Having purchased a tire pressure monitoring system, the light bulb moment was figuring out what to do if the pressure was low, This solves that problem very nicely. The item is well packaged and the carrying case is large enough to fit everything back in when done.
I had 2 issues when using this. The first is that if you don't identify properly which of the two air hoses must be connected to the air compressor, you are in for some head scratching. The labels are a bit misleading but one more clearly identifies the proper air hose. My second problem was that the air hoses didn't easily seat into the connection. I am hoping that with time and use, it will get easier.

Filling the tires was a breeze. It was very quick and not very noisy. The automatic shut off is a nice feature. Also, the included air pressure gauge was within one pound of a digital gauge that I used to check it with. As pointed out in the video, if you are connected to shore power, you can connect to the house batteries and don't need to run the RV.

I have a 125lb. psi Craftsman 5 gal compressor, but it doesn’t push enough pressure to fill a 19.5” tire to 95 psi.

I think I must’ve been TechRV’s first sale of the ViAir 450P-RVS. I heard about it at the annual Escapees Rally, Escapade59 in Tucson and was waiting for TechnoRV to offer it.

It is awesome. I was going to time how long it would take to fill a tire, but it was so quick that I forgot to check how long it took. It wasn’t long enough to even be concerned. Within a few mins. I had all 6 tires within 1 lb. of each other and just the right pressure required for my rig’s weight.

By the way, in case you don’t know...Most gas stations don’t have the equipment needed to fill your tires either.

Man, this little compressor is an animal!
While I only have a fifth wheel, I decided to go with this unit because I pull my trailer with a dually and I wanted to be able to air my rears with the chuck this unit provides. Glad I did!
Thank you TechnoRV for providing a great product at a great price!
