Viair and Air Zenith

I got one Viair 400, and I also have only a 145-175 pressure switch. Would I have a problem hooking up an Air Zenith compressor with it. RUn both off the same pressure switch. I know I won't be getting all I can out of the Zenith, but I just want my re-fills to be faster.

Also, do Zenith's ahve a check valve like the Viair does?

It will work, you need to use relays or Ford type Sol.

Ford sucks, get a continuous duty one for a plow or something, those are the better ones.

this is the relay I got. Can I run both compressors off one of these. It's 100 amp continuous.

Yup you can no problem...

Not to jack your thread Blitch, but I have a question... would running a continous duty Solenoid with 2 compressors be good enough, or should I run relays also
