PLANT AIR (CENTRAL COMPRESSED AIR SYSTEM)
Manufacturing plants with central compressed air systems should have an after cooler and a 2-stage
needed. To verify that the plant air system is adequate for the Aero 40FP, the air compressor needs
to produce an air volume 10% greater than the Aero 40FP maximum air volume in addition to the air
volume consumed by normal plant operation. To determine adequate air volume, watch the pressure
gauge while blasting.
• If the gauge drops quickly, there is a restriction or the pipe is too small.
• If the gauge stays steady, then the compressor and piping are adequate.
To maintain adequate pressure to the Aero 40FP:
• For distances less than 100 ft (30 m) between the air compressor and the Aero 40FP, Cold Jet recommends
• For distances greater than 100 ft (30 m) between the air compressor and the Aero 40FP, Cold Jet
recommends a larger hose/pipe to maintain adequate blast pressure.
rust may have collected in the line. Before connecting to the air supply, purge the line to
prevent contamination of the Aero 40FP.
