Compressed Air
Ordinary compressed air filters have always consumed too much energy, as
they are by design, a restriction to air flow. During their working
life, this restriction increases dramatically, and typically over one
year, can consume more energy than they are worth. Technically, service
life is dependent upon differential pressure. Most manufacturers
recommend a replacement filter element at between 500 mbar (7 psi) and
700 mbar (10 psi) differential. This will cost you a massive 5% extra
in compressor energy. In fact you are driving your compressor with the
brakes on!
