Air Compressor

(1/3) > >>

Steven Harper:
We have a 2008 Beaver Contessa.  When we bought our motorhome we also bought an extra long air compressor hose in case we ever needed to inflate our tires.  My question is this.   Does the motorhome need to be running when we use the air compressor which is located in the generator compartment?

George H. Wall:
No, but the generator does, it powers the air compressor.

Joel Ashley:
If you use the air chuck connector that comes off the air tanks, you should find 110 to 130 psi available.  I also bought a long air hose, but had to get the correct fittings to match the coach's female quick connector.  I've never actually had occasion to use it in practice, but would assume one would run the engine to maintain tank pressure.  The connector is also used by tow trucks to maintain system pressure (brakes and bags) in your coach when towed.  Unfortunately, though most coach's connectors are in front with the generator, and easy to get to for a tow truck's air line, ours is back in the battery bay, requiring 40 feet of air hose draped over side mirrors and bungied to awning arms all the way back.

Richard And Babs Ames:
Your engine air compressor does not have a lot of air storage capacity so needs to be running when using the air hose. If you have a fast idle it will increase the volume a bit but it is not designed for large volume applictions.

LEAH DRAPER:
If you don't have the engine running and on "fast idle" you'll have a hard time getting the pressures up for tires on our coaches.  I used to try inflating (topping off) without the fast idle and was never successful.  Then I learned from another Beaver owner the secret of fast idle.  Yes it sometime takes a little time to get to the desired psi, but it does work!
