Pass or fail?

A recent post on Pneumatic Tips shows the impact of oversizing when going from piston to rotary screw compressors. We’ve compared piston compressors to rotary screws several times, but this post presents an example illustrating the fact that proper sizing is an important factor when choosing an air compressor, not just what type of compressor it is.

Tips on buying screw compressors

  • Don’t buy bigger than you need,
  • Multiple smaller compressors run more efficiently than one large unit,
  • Most screw compressors can turn off between load cycles if there is adequate storage receiver capacity, and
  • Adequate storage means having about 5 to 10 gallons of receiver capacity times the output of the main compressor.
