Can someone ID this compressor?

CCWKen on Fri July 17, 2009 1:17 PM User is offlineView users profile

Year: 1926
Make: Ford
Model: Model T
Engine Size: 176ci
Refrigerant Type: 134a
Country of Origin: United States

I thought the year would catch ya!

I'm looking for small compressors that would fit this application. The engines on Model Ts only have 20hp so the power draw would have to be low. Running rpm is from 400-2000 with cruising rpm around 1000-1600.

Could you get us some numbers off that nice yellow tag there. Should be at least a model number.

Since you have to make drives & brackets anyway for T's, A's etc., just go with a V5. Hard to beat a compressor that will destroke when the load drops, and offers evaporator pressure control built into the deal. Simple, no extra switches or thermal sensors.

Presumably you are running a 12v electrical system for cabin blowers, clutches etc.

If you really want "vintage", you could do the A/C like the 1932 Chevrolet coupe I used to ride in as a kid in Brawley, CA. The evaporator was a long tube that went across above your head like a tube & fin unit - with no fins. It continued down the back wall of the cabin the same way. Probably 60 feet of half inch copper. The compressor was a single cylinder unit from a stationary installation. No clutch, it ran all summer - remove the belt in the "winter".

That to me looks like a TM-08 and we do have that compressor available. You are looking at $256.50, if you click HERE it will take you to that item on our store.

Thanks for the replies. It doesn't have to be this exact compressor just one that wouldn't draw more than say ~2hp. What you see is what I got--Picture. No numbers available. Here's another "example" but a different compressor.

I agree with Bohica, a V5 would be good for building a system from scratch. They're readily available, somewhat durable, and not expensive. You can switch the pulley with one from practically any GM compressor to get the belt size you need. The variable feature is a huge plus here, you don't want the compressor to cycle on and off, abruptly grabbing and releasing a large proportion of your very limited horsepower. The rest of the system should be TXV with a parallel-flow condenser. Ideally the belts would be set up to spin the compressor at about 6000 rpm with the engine at redline. If that is not practical you might consider a V7, it's larger displacement would let you under-spin it. Cooling the interior of a model T, though it is small it has a black exterior and no insulation may take quite a few BTU's.

The second car appears to have the condenser somewhere in the rear, and no radiator fan?

I don't believe 6000rpm is going to happen. That would probably take a 20" pulley on the crankshaft! Rpm at the compressor is going to be limited to about 1600rpm max just because of the pulley size on the crank. It can't be larger because it sits inside a "cup". Red line on these engines is about 2000rpm and the crank pulley can't be larger than about 4". Few engines will ever see above 1600rpm so the compressor will be less.

The engines have a fan, you just can't see it well in the pictures. Yes, the condenser would be electric fan cooled and mounted under the body. These engines didn't even have a water pump.

Given the very low engine speeds & pulley issues, I would go V7 then. Serpentine or "V" pulleys, ear or pad mount are all available.

Here are the performance curves for the TM-08.
