Devair PD50 Air Dryer - Run Capacitor Size/Specifications?

[Jaarreedd]

I recently purchased a Devair PD50 ProDry refrigerated compressor dryer, and unfortunately the run capacitor was missing from the unit. I have reached out to Devair (now DV systems), and the unit has been discontinued long enough that they neither have specs for the capacitor itself, nor documentation to be able to figure it out.

AllParts has a listing for the dryer and the PDF manual which contains the relevant part number, but that number doesn't get a hit anywhere for purchase, nor have I been able to find the capacitor specs. For reference, the PD50 capacitor part number is 5910.103.13, which is for the 115V, 1PH, 60Hz spec that mine is. The space where the capacitor goes has a bracket indicating it would be an oval shaped body, and there are 3 wires that are supposed to connect to it.

Any chance someone on this forum has either a Devair PD50 or PD75 (they share the same cap P/N) that they can snap a pic of the side of the run capacitor from? This would be a lifesaver if so and much appreciated.

I have attached pictures of the Dryer label, compressor pump label, and the electric fan motor as well. None of them have uF ratings noted so this is a bit more challenging.

Thanks in advance!

This is probably a Hankison dryer. They might be able to help you.

I've used these--or similar:

in similar situations. They often solve the problem.

A hard start pulls out of the circuit after the motor starts. He needs a run capacitor.

Looks like the same machine as a HIT50. Check the compressor specs.

According to a search, the part number for the run capacitor for a 115v unit is 7440387.
This is making a couple of assumptions, so take this as a suggestion, not gospel.

The pictures in the DV Systems and Hankison manuals are exactly the same
