Fine bubble air disc diffusers Diffusers designed for aeration of activated sludge basins and tanks in Municipal and Industrial wastewater treatment plants. Quick and easy to assemble by Rotating Diffusers clockwise into Screwed connection. Designed to give optimum performance. DIFFUSER BODY The manufacture of this component in Glass Reinforced Polypropylene gives it excellent resistance to abrasion, most chemicals with significant mechanical strength. EPDM MEMBRANE The EPDM Membrane prevents the penetration of water into the distribution pipework when the air is stopped. 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. THREAD 3/4’’ CONICAL GAS TYPE FITTING Allows Aquadisc® difusers are mounted by simple turning clockwise

Prevent operating room infections by absorbing infectious fumes POREX ® porous fume absorbers are used for the convenient and efficient eradication of noxious fumes generated in the cement-bone mixing process during surgical procedures in hospital operating rooms. Designed with porous plastic disks that surround activated carbon material, POREX porous fume absorbers create a porous fume filter that supports balanced air flow rates, optimal back flow pressure, and out-gas residence times. Accommodating device fit requirements with its specified part geometry, our porous fume absorbers: Prevent toxic fume and gas escape in operating rooms–Effectively absorbs fumes and gases, preventing exposure in operating rooms. Balance airflow with residence time for optimal absorption within a specific device geometry. Easy press-fit assembly–Complex layered component is designed for a simple press-fit assembly into the mixing device.
