[SEL] Binks Air Compressor Data Needed

[FRM8198 at aol.com]

Hi List,
I have an older Binks Lo Boy compressor.  Instead of an  electrical pressure 
switch to control the predetermined output,  it has some sort of an internal 
clutch to disengage the compressor from  pumping more air when the set pressure 
is reached.  When it is in the  latter mode, when maximum pressure is 
reached, the motor/compressor pulley  continues to run without a load.  
Does anyone have any technical data or parts lists for this type of  
compressor?  Is there any other make that uses a similar control  system?
