Storing aux compressor in engine bay
« on: April 29, 2020, 02:32:00 PM »
PO of bus had placed a pancake compressor in the engine bay as seen in the photo. It was not there when I got it so wondering if the heat and elements in that location caused damage. It's all wired and plumbed so tempting to put new one right back there.

Could be the heat did it in, or it could be that the compressor was too small for the job. Most pancake compressors I've seen are not meant to run at 100% duty cycle, and even to fill a few tires is a big job for a small compressor.

Before buying a replacement, figure out what you plan to use it for to make sure it's up to the task.

For about $100 a HF pancake would be a pretty painless test.

Airing up the coach is a big job.

Nothing wrong with the location, everything would be cool, when usually called upon to air-up?

Choose the larget cfm @ 90lbs you want to spend money on, that will fit in the space, and uses the AC voltage you have available.

Do not choose a compressor based on HP, it is the pump rating, not the crap electric motor rating, that moves air.

The tank may be discarded for sizing, the bus already has tanks...

For bonus points, some sound control for stealthy use would be lovely.

Happy coaching!

@BW - thanks for the nod on placing inside the engine bay. I'm adding a shroud of EHP or Reflectix to shield the direct heat while allowing air circulation.

I bought on sale the Rigid 6 gal 150psi, 2.6CFM @ 90psi

It does take some time and gets a workout. However, the original warranty is 3 years and an added 2 years warranty through using Costco Anywhere Visa card, for a total of 5 years. Keeping paperwork and bus so it's very good value, especially anytime it fails I'll just get another.

I have a Thomas 12V compressor in the Country Coach I haven't look at the CFM but it pumps the coach up in a hurry using the coaches tanks for storage, compact and does the job plus quite too

Remember, for a quick get-away from the campsite, the air doesn't have to be full, it just has to let the brakes work.

Saves some compressor life.

From the image, the tank is not visible, did you remove it? Did you allow for sufficient ventilation?

Stripped to the essentials, that's a nice tidy install Boomer!

Strip the tank, just fills space and blocks air movement.

The tank can be re-purposed to being an air pig around the homestead, or whatever other creative function a busnut may dream up.

You never meet Mark (Boomer) he covers all bases and little details before the install
