120v air compressor usage times - encantotom - 07-23-2019
i did a very un scientific analysis on how much my 120v compressor is used.
i have been sitting in the same place for nearly 4 months.
on april 7 i decided to take a picture of my compressor hour meter. i did the same thing today on july 23rd. 107 days
on july 23, it was 1870.3 hours
on april 7 it was 1798.8 hours
so has run 71.5 hours
107 days and runs for about 5 minutes each time so 71.5x60/5= 858 times but to be honest i have not really timed how long it runs. if it was 4 minutes it would have been 10 times a day.
858/107= 8 times a day
so every 3 hours or every 2.4 hours or something like that it runs for
i have 2 air power toilets, a bode air entrance door, two interior air pocket doors, a bay fridge on air slide.....all of which we use. the doors get opened and closed alot. toilets get flushed alot. etc. plus i dump the sewer tank every 3-4 days. leveling system is not in autolevel.
in that 107 days we have been gone from the coach for 3 days once, 2 days once, and a few all day times. we are gone from 7am to 1pm everyday. and i did try using the 12v compressor only for a couple of days......so throw all that in your calculating minds. none of which i included in my calculations.
so like i said, not very controlled
for your reading pleasure

Tom,
That sounds like you have a really tight system given what you operate during the day. I have timed the 120v compressor cycling on our coach at 3:35 per cycle. The coach is in Auto Level with no other air system items being operated during that time frame.

while spending alot of time in the shop lately, i had my coach on the 120v compressor.
i timed it and it comes on every 4.5 hours without using the airdoor.

It looks like I have most of the leaks under control now. The 120V compressor runs for 1-1/2 minutes every 2-1/2 hours using no air doors, toilet, leveling system off, etc...

Very good Ron.

I’m replacing leaky 1/4” push in air fittings. I’m thinking my coach still has the original 1/4” air lines running to the HCVs. I’m curious if anybody else has had trouble with those old lines? I’m trying to decide whether to replace them.

Dean,
In the 14 years that I have been following this forum, and the original Newellclassic forum, I do not recall anyone posting about a failed air line. Push on fittings, yes, constantly, but I just don’t remember burst or split air lines.
A general comment about compression DOT fittings, you don’t have to gorilla them tight to make them airtight.
RE: 120v air compressor usage times - rheavn - 04-24-2021
I have not discovered a single air line burst or split either. I did find a rubber brake line chafed through. 99% of the air leaks I have found were without getting under the coach. Replacing push in fittings is a no brainer---they leak. Only replace with good quality DOT compression fittings. Don't forget to check inside the coach. Parking brake valves can leak. Brake pedal valves can leak & mine had leaky push in fittings. Air doors, toilets, etc.
The only push in fittings I have on my coach are on the dump air valves. Never found a compression fitting to replace them.

Right on Richard! And make certain you use the brass sleeves that slide into the tubing. Get them snug by hand then maybe a 1/2 turn or so and they shouldn't leak. If you're replacing a pushon with a compression fitting remember you have to compress the sleeve so it'll be a bit harder than when re-tightening an existing fitting. It's only 120psi max and lower in some cases like the bladder etc.

In the weatherhead catalog, there are cardboard rings in various diameters fo the size of fitting and the thickness of the ring is to be used as a gauge. The nut is removed from the fitting, a ring is placed on the threaded portion and the nut re=installed. When the nut touches the ring upon tightening, it is at the proper tightness.
I found these when purchasing large fittings for fuel transfer lines. They were a valuable addition to the installation. The technicians installing the fittings had definite limits on tightening. The size involved was 5/8OD. The rings are available from #4 and up.
