THREADS: 1-1/4″ NPSM

Compressor –  most important part of  a blast cleaning system.

An important thing to remember is that your compressor needs to supply air with constant high volume and constant high pressure. There is no point having high pressure and low volume or high volume and low pressure! Your system will not work efficiently and watch out for any pressure drop between compressor and your (new) blast cleaning nozzle. There are several areas in blast system that contribute to pressure drop:  (1) length and I.D. of air hose,  Air lines running from compressor to moisture separator. (2) Moisture separator and (3) Length and I.D. of blast hose.

Air supply valve on compressor will point to minimum I.D. of air hose you should use i.e. do not use ¾ or 1” ID air hose on a 1-1/2” compressor air control valve. This could cause a pressure drop between 5 and 20 PSI. Air hose should have a smooth inner wall. Coarse textured inner wall on air hose will also contribute towards a pressure drop.

Air pressure at nozzle can n be checked using a needle gauge. The compressor air control valve can then be adjusted (and if possible locked) to maintain pressure at nozzle of approx. 100 psi. Never subject any blast cleaning equipment to a pressure over 125 psi or manufacturer’s pressure rating for your system.

Another important contributor to a system wide pressure drop is a worn blast cleaning nozzle!  When bore has worn by approximately 1/16″ over its  original  bore size nozzle should be changed or CFM has to be increased to maintain nozzle pressure.
