York Air Compressor CFM Ratings (on the truck)



snaked from the J--P list!



From: John Nutter <jnutter com="">

Subject: re: york compressors</jnutter>



I found the displacements of the different York/Techuseh compressors in an old JCW catalog a while ago. Here they are:



 






























Model Displacement (cubic inch per rotation)
F206R 6
F210R 10
R209R 9
R210L 10
T210L 10




To decode:



first digit

F= flange top

R= roto lock

T= tube-O



2nd digit:

2= 2 cylinder



3rd and 4th digits - cu.in displacment of air during one rotation



5th digit:



R= right hand suction

L= left hand suction

Bill Blair compiled this shortspread sheet of Engine RPM = CFM output of a converted Air Conditioning Compressor to an on-board Air Compressor system.



This assumes a Compressor Pulley of 5" diamater, and an engine pulley of 6" in diameter.



CFM=(CID*RPM)/(12*12*12)*(Drive_Pulley_Diameter/comp_pulley_diameter)



 













































Compressor Cubic Inch Displacement Cubic Feet per Minute Output @ Engine RPM
  1000 2000 3000 4000
6 4.17 8.33 12.5 16.67
8 5.56 11.11 16.67 22.22
9 6.25 12.5 18.75 25
10 6.94 13.89 20.83 27.78
