How many CFM's Required to Pressure Test MH?
I need to help out a friend who has a class C with a leak. For those that have performed the pressure test can you tell me what is a good CFM for a test blower to pressurize the unit? Thanks in adv...

I've thought of building a pressure source with a jobsite ventilation blower. Mount it to a piece of plywood with a foam gasket to seal to ceiling around the 14*14" bathroom vent. Hold it in place with battery hold-down bolts.
Two blowers from Harbor Fright. I tried to size the pix to approximate the dimensions given on HF's specs:
The $79 yellow one is rated around 1500 CFM and the $49 red one is 300 CFM. Wish I could be sure that Red's capacity would be enough.
Also, Yellow could be easily mounted to the bottom side of the plywood adapter I'm thinking of. I'm sure Red has an intake on the opposite end that isn't pictured. It'd take some kind of ducting to provide air to both intakes.
From what Golden says, the Red blower might do it and the Yellow should...
A BIG Shop Vac might provide enough air in Blower Mode too. To me, it shares the Leaf Blower Limitation of how to connect it to the RV.
