I have a compressor powered by a 3 HP electric motor,mounted on a plate, being used to pump air into a water well and I cannot identify the compressor.


There are 5 digits stamped on the side.

I have read many of your comments and your information regarding Speedaire and Graingers. The owner believes that it was on a craftsman air tank before, but no certainty.

In order to obtain a proper parts order I need to know which compressor model it is.

I am sending you a picture to aide in the identification.

The cylinder wall may hold the key to it's identity as the air vanes travel vertically only.

I have a similar compressor assembly, so we removed the head and cylinder to see if the pumps were the same.

My own compressor had smaller in diameter pistons and the brass output compression connector is smaller as well.

My compressor model appears to be a Sears model number 106.173781. It appears to be of the same family as the cylinder cooling vanes also travel vertically.

The person that I bought this unit from gave me paper work so that I am certain of the identity.

The numbers stamped on the pump in need of identification are one of 4 possible numbers. Either E266B, E268B, E288B, or E2888. The stamping machine did not press as hard on the top right hand corner, so the last 3 digits could be sixes, or eights, or B's. I hope that you can offer some assistance.
