Questions & Answers

As advertised on the VIAIR website, this pressure switch operates at 110 psi on and 145 psi What happens when the pressure is off by 145 or 150 psi?

There is an error of 145. Compressors will be automatically turned off when air pressure reaches 145 in the tank. The air horns will work just fine at 145 or 150 if you use it for this purpose.

In order to add a second compressor to my Viair 450C kit, I need a 2. Is it possible to connect both pressure switches and relays with a single pressure switch/relay? Can I use a single compressor or require one for each?

Hello,*br>To handle this, you will need two relays (93940) and a pressure switch (90102).

The warranty cover is for one year. How do I get a replacement?

There isn't much to it. *br> *br>Contact Viair either by phone or by email to get started. The receipt/proof of purchase must be brought with you. A copy of the receipt from Viair is required for any part warranty. You can contact them and explain your issue to them. You will be able to troubleshoot the issue with them. *br>Viair will request your receipt if you do not resolve the issue within your warranty period, and you are still within your warranty period. After that has been received, they will be able to set up a replacement unit under their warranty process.

Is it possible to use this switch with a water pump as well?

In carb installations you will need a fuel pressure switch to be wired into a 12v relay wired to neg. or to pos. This will turn on or off the water pump depending on the psi. There is only one 12v switch listed here, and it is for 110v The air pressure should be 150

Water reeks of bad odour
3/5

Three pressure switches later, I'm going to stop. The compressor is mounted in the pick-up box and protected from the elements using the The last failure was caused by overflowing water as a result of washing out the box. A customer service representative informed us that moisture will lead to a failure of these switches. Their point of view is correct. The last one, the third one, have been working fine for more than a year now after I sealed both cases with silicon RTV sealant. My next purchase will be a different brand and style if the first one fails. Suitable for installation on top of a vehicle, but not under it. I would rate this switch as junk due to the popularity of Viair compressors.

Fix for my $900 air horn for a fraction of the cost
5/5

For my Ford F350, I have a HornBlasters Conductor Special that I enjoy very much. Within two months of no longer being under warranty, it stopped working. As a result, I replaced this part myself, sourcing it cheaply from the local hardware store. It is evident that the wires are well marked. Hence, I consider the horn to be my "antidepressant" In a car- Texting while driving It's the device. " I like the way this works.

It does the job a long time
3/5

I just ordered my third unit, claims to be moisture resistant, but it's not. If I ever found a better air conditioner to run my truck's air tanks I would be very At least for the time being, its cheap enough to buy another and plug it to get it back up and running again for a while. It says its capable of 10,000 operations, but I doubt it, I haven't come close to it in either of my previous.

I like it a lot
3/5

Very easy to set up and functions well. But after 5 months, the update stopped working. As soon as the overpressure blow off valve kept going off I began noticing something wasn't right with it. Now, it doesn't work at all. After going into failsafe mode, finally it shut down. Has a short enough life span that it cannot be recommended as a gift.

The original one I got failed within 2 weeks, but I received a replacement without any hassles, and the product has been working great since then as well.

The cut-outs do not stay on long enough to reach 145 pounds of pressure.
