The largest electric air compressor in the Speedaire air compressor family that we could find is the 10 HP, two stage (2 cylinder pumps) unit delivering about 34 CFM at maximum pressure and shown in the image below. 9 HP, 120 volt tire compressor putting out 115 PSI at a massive flow of 1.7 CFM. I am assuming that these may be easy fixes or something that can be solved by rebuilding the pump but really need to be able to id it in order to get the right parts. The smallest Speedaire compressor we have found is a. I have a head gasket leaking & there is air coming out of the weep hole in the top of the housing that the shaft come through at. The flywheel looks identical to the 1 in the picture.
Speedaire compressor 4 serial number#
The serial number for the compressor itself starts with 04207. The pump has a raised inscription that says B 17B. I am not sure if the plates on top of the pictured pump are removable and the box I speak of may be underneath. The pump is a 2 cylinder model that is much like the attached picture except that the middle bolt is recessed onto a box that has the air inlets and is normally covered by felt type of filter. It appears to be a 2 part sticker as I still have the Speedaire title part. Portable Air Compressor, Electric, Single Tank Type, Voltage 120 VAC, Amps AC 15, Running Motor HP 2, Free Air CFM 90 PSI 5.5, Free Air CFM 125 PSI 4.9, Free Air CFM 135 PSI 4, Max Pressure 135 PSI, Tank 13 Gal, FNPT Outlet 1/4 In, Cast Iron Cylinder, Oil Lube Design, Length 30 In, Width 18.0 In, Height 26. The model# sticker is up on the shelf where the motor & pump are. There is also a darker gray & yellow maintenance sticker on the same side. The tank & pump are almost a primer gray in color with a red & silver Speedaire sticker on the non-flywheel side. Electric Air Compressor: 2 hp, 1 Stage, Vertical, 30 gal Tank, 4.9 cfm, Splash Lubricated. The big problem is that the sticker that had the model # & information on it is now gone.
I need to order some parts & so far none of the parts I have numbers for have shown up on Grainger such as the belt # (Durkee-Atwood BT-31) or the motor which is a Dayton LR22132. I have a pretty old Speedaire 2hp 20 gal portable that I am trying to determine what model pump is on it.
