Compressor RPM

edited December 2013 in General
What is the Max RPM I can run a SD7 at?


  • There are three different specifications.
    SD7H15 Heavy Duty - 6,000 RPM
    SD7H15 Sealed Heavy Duty - 4,000 RPM
    SD7H15 Super Heavy Duty - 6,000 RPM
  • Sealed heavy duty is rated at a lower RPM because of the felt rings used to seal the clutch assembly. If the RPM is above 4,000, it will prematurely wear the felt ring and expose the clutch assembly to particulates.
  • dont worry! I use sd 505 in 2.od deisel 2000 cc toyota.nothing happened perfect cooling
