Product details

Overview & performance

Micro-pore disc aerators use an EPDM or silicone membrane pierced with fine micro-pores. Air is distributed through the membrane to produce fine, uniform bubbles that rise through the mixed liquor, giving efficient oxygen transfer with lower energy use than coarse-bubble aerators.

Key features:

Fine, uniform micro-pore bubbles for high oxygen transfer efficiency.
EPDM or silicone membrane to match service conditions — EPDM for general service, silicone for higher temperature or specific chemical conditions.
Good backflow prevention and low resistance, with a strong, durable body.
Easy installation on aeration pipework; several diameters to suit different tanks.

Specification: diameter 215 / 260 / 300 mm, EPDM or silicone membrane. Uses: aerobic tanks, aerated biofilters, activated sludge and aquaculture systems.
