Not sure if my old SpeedAire Compressor (1Z286E) has PRV (pics included)
model 1Z286E Speedaire air compressor
Hi there I have an older Speedaire air compressor that I picked up at a yard sale, its model 1Z286E, with compressor model 2Z157B, with the 1/2 HP electric motor.
It does not look like it has a PRV valve. It does have push slide valve? Im assuming that is a type of cutoff valve? Im new to air compressors.
If this one doesnt have one can I add one pretty cheaply? Can you take a look at my attached photos to see if everything looks to be there?
I don't see a PRV either, though I cannot see the back side of the Speediare air compressor.
In the first photo of the manifold I see what appears to be the tank gauge to the right. The red-knobbed item I take to be where the regulator is / was, though I'm puzzled as to the fact that you don't have a regulator gauge.
Protruding to the right of the red cap is what looks to be a capped line. If it is, that's a good spot for the PRV, as it would "read" the tank pressure satisfactorily from that spot.
If what is located at the red cap area is not a regulator, that's where I would install one, so that you could regulate the air pressure coming out of the discharge coupler to the left in the image.
I shown a link below where you can obtain PRV's if you wish. Hope this helps.
