Weighted EPDM Matala diffuser

Microperforated EPDM membrane diffuser which is already weighted: it is ready to operate.

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

As the pores open under the impulses of the pump, the bacterial biofilm cannot easily be deposited, which prevents the usual clogging of ordinary diffusers.

The convection movement created by this aerator is excellent for oxygenating the pool. The lower water layers are thus raised at the surface by a convection effect, and are enriched in oxygen by the air / water interface.

The goal is therefore not to oxygenate the pool mainly thanks to the air bubbles emitted by this diffuser (the bubbles which rise do not have time to release a lot of oxygen anyway!) But to oxygenate the pool by convection effect.

The minimum recommended flow rate is 20 l / min per meter of pool depth: in summer, the flow rate must obviously be adapted.

Choice of two sizes: 130 or 180 mm.
