EPDM cylindrical diffuser 60 cm

EPDM membrane diffuser microperforated cylindrical type: very used for the aeration of filters.

This membrane causes a column of fine bubbles: when the air pump is stopped, the pores of the membranes close, preventing the intrusion of pollutants.

Since the opening of the pores takes place under the impulses of the pump, the bacterial biofilm can not easily be deposited, which avoids the usual clogging of ordinary diffusers
