The SnapCap™ coarse bubble diffuser is designed with a snap-on diaphragm cap, manufactured with an EPDM-based thermoplastic rubber that offers added life and enhanced performance.
It is comprised of two plain elements which is the versatile snap-on diaphragm cap and a support base.
The diaphragm extends from the base during aeration while enabling the air to pass through the diaphragm's orifices. The diaphragm is then quickly sealed against the base through the fluid's pressure head, limiting backflow and clogging during air stoppage.
