What are the main features of the VIAIR?

  • Many uses including air horns, tires, load-leveling and more

While it is designed to be mounted in a protected area, there are allowances made for exterior use.  One of them is that the air filter can be relocated if you are going to be using it in a harsh environment.  In reading through manuals and literature, I have found that the VIAIR is water resistant rather than water proof.  I have tried to read between the lines and a harsh environment means lots of dust and dirt but not exposure to rain.  If this is your intended use, please read the warranty information carefully so that you don’t inadvertently nullify the warranty.

Given the reputation that the VIAIR Corporation has, I believe they would stand behind the product, but it is always better to check first.  Here is how the warranty reads:

VIAIR Corporation warrants this product, when properly installed and under normal conditions of use, to be free from defects in workmanship and materials for a period of one (1) year from its original date of purchase. This warranty covers product defects only. It does not cover incidental or consequential damages as a result of misuse or abuse.

What is the verdict regarding the VIAIR 150 PSI High-Flow Air Source?

I have read many customer reviews as well as blog comments and as much information as possible on the company website.  The air compressor is almost universally praised.  Many people commented on the ability to buy more components and expand the uses of the basic compressor.  Our recommendation is that if you are going to use this as intended, it is a great on board compressor.   Read on for customer reviews.

Customer Reviews


Purchased horn set in 2005. Just installed in my truck 3-2012 The compressor and tank set up is outstanding. Base fill time is about 4-5 minutes. But after horn use, about 3 second blast, takes about a minute to refill. Very pleased with compressor and air tank. Have mounted in bed of truck, plus I have a topper,so compressor is not exposed to weather conditions. Have checked tank several times thru out the year, has never had even the slightest amount of moisture released. Excellent design compressor & air tank. Read More..


This kit is awesome. Last time (about a year ago) I installed a compressor kit in my ’95 T100, I pieced together all of the components separately, because I thought I was going to save myself a few bucks. Lets just say, I was wrong. I had to skimp on quality components to keep the price down. This kit was more than a pleasant surprise after all of that. It came fully assembled with only a positive and negative lead that need to be hooked up for it to work. Very simple, and all high-quality components (Viair is a very well-known name brand in this industry).  Read More..
