Components
1

DIFFUSER BODY
The manufacture of this component in Glass Reinforced Polypropylene gives it excellent resistance to abrasion, most chemicals with significant mechanical strength.

2

EPDM MEMBRANE
The EPDM Membrane prevents the penetration of water into the distribution pipework when the air is stopped.

3

CLAMPING TYPE
AQUADISC® 250-305: Clamps are manufactured in stainless steel or polypropylene and secures the membrane to the diuser body;

AQUADISC® 320: Clamp made of glass fibre reinforced polypropylene.

4

THREAD 3/4’’ CONICAL GAS TYPE FITTING
Allows Aquadisc® difusers are mounted by simple turning clockwise
