is this the Condensor you have?

SKIRT MOUNT CONDENSER 41,400 BTU/HR (10,433 KCAL/HR) 95CFM

if so that has a pretty high power fan on it... that one had the reefer style fan in the Pic...

The condenser looks about right but the fan is totally wrong. It's a 14" fan. I was able to find a tag on the fan shroud but can't find it online. Possibly the fans were retrofitted to replace those reefer ones? Photos coming in a second.

In order:

Label from the rear unit
Condenser hole for fan mount on the front unit, looks crudely cut
Front fan removed
Rear condenser with fan installed

it definitely looks like they modded the units to use different fans... these things should definitely be puller fans..

I should be able to find the specs on the ProAir fan.. it looks like a SPAL or flex-a-lite knockoff..

Derale makes some really nice hotrod fans..

they arent cheap but they move air! im not sure how much amperage your current fans pull however this fan will have a decent surge current and probably pull 25-30 amps running. it can be wired as high or low speed.. high speed will likely move over 2000 CFM of air. as a puller..

https://www.summitracing.com/parts/d...hoC9s8QAvD_BwE


you need to make sure that you are properly fused or breakered / wired to use this fan.. but it will make your condensor stay cool.. if you are building an arduino or RPI set up you could even wire its high / low speed up to match the temperature of the Liquid line coming off of the condensor...

Derale fans arent quiet.. however this is your Engine air so theres already the noise of the 444E anyway.. you wont hear the fans..

I can look for other options if you like..

your system does appear to have a sight glass.. in the bottom picture to the right of the receiver dryer canister theres a hexaganol flat , that should be your sight glass.. wipe it off and should be able to see in.. it may have a Plastic dust cover on it that pops out..

My HF meter says the fans I have pull around 5 amps, the front one has a tag that says 80 watts. They are puller. A pair of 22 amp fans might blow the bus over!

as for overkill - im just trying to keep you from ruining more compressors.... and keep your bus cold inside...

I know when we were at the last ECCB gathering and I was in your bus that the front unit at that time definitely wasnt cold like it shouldve been.. it was cool...
everyone was more into the gathering than wanting to hear me talk about A/C .. and I think you mentioned it might be low on freon at the time..

the principle of A/C is that the amount of heat you wish to remove from the inside of the bus must be removed by the condensor on the outside.. the freon simply "carries" the heat from one place to another... a messenger so to say...

Yeah I think my meter is preventing it from getting more. Audibly it isn't spinning as fast through the meter as directly connected..m

Just ordered a pair of those fans, couple bucks less on Amazon, delivery Thursday. Still need to replace a fitting but we are sitting tight through the week here.
