The job of the filter purifier is to separate liquid and solid particles dispersed in the compressed air with a high degree of efficiency.
This separation is ochieved by means of a special filtering element called a 'coalescence cartridge'.
It is particularly indicated for eliminating traces of oil present in the compressed air. The air flow rate must remain below the maximum values to ochieve the desired degree of purification, beyond this value, there may be a dedine in the quality of air from the purifier.
On the front and back there is a port (1 /8* for size 1 and 1/4' for size 2) that can be used with pressure gauges, pressure switches or as an additional air intake. The air taken from here is not purified.
