OTT MAGNUM® Diffusers – Patented Technology for Rapid Installation
Stainless-steel clamp bands. Located at both ends of membrane, i.e. beneath each inverted membrane end.
FLEXSIL® or FLEXNORM® tubular membranes are ideally suited for a wide range of wastewaters and applications. Their consistently high performance and reliability are ensured by highest quality standards and stringent quality assurance. Each diffuser carries a printed lot number for QA traceability.
OTT diffuser bodies are designed with a patented geometric shape which ensures a wrinkle-free membrane even when air infeed is discontinued, e.g. in intermittent operation. This unique feature is essential for maximum integrity and service life of the membranes.
MAGNUM® diffusers incorporate precisely engineered perforation which provides outstanding bubble distribution and uniform air release. This clearly sets us apart from competitors – as demonstrated by numerous trials conducted by independent test institutions. Custom perforation can be provided in accordance with your specific requirements. For more information – contact us!
PP Diffuser Body
The body of the MAGNUM® diffuser is a monolithically injection-moulded tube made from eco-friendly, recyclable polypropylene (PP). Its expertly engineered shape and construction provide users big benefits.
Mounting of MAGNUM diffusers is quick and easy due to the CLIPIN® locking latch which makes MAGNUM the installation-friendliest diffuser on the market.
MAGNUM® diffusers are available in a wide variety of dimensions. They can be installed on rectangular laterals or on round laterals.
Continuous Air Channel
MAGNUM® diffusers incorporate an end-to-end air channel at the bottom of the body which ensures uniform air distribution along the diffuser’s length.
MAGNUM® diffusers are open at the body‘s outer end, permitting partial flooding and therefore reducing buoyancy.
MAGNUM® diffusers are available in effective lengths of 1000, 1500 and 2000 mm. The overall diffuser length of each version is 200 mm longer.
Connection to AirRex® header system.
1″ Female Thread
For direct connection to dedicated downpipe. Ideal for grit collectors and similar applications.
OTT MAGNUM® diffusers are installed on laterals as integrated twin-diffuser units. Their CLIPIN® connectors permit rapid installation on stainless steel and plastic laterals of all types.
The monolithic PP diffuser body provides reliable service at operating temperatures up to 120°C (248°F) and is fully resistant to formic acid.
MAGNUM® can be installed on laterals with 30 or 38 mm diameter (1.18" or 1.49") outlet openings located at the 12 o’clock position (i.e. facing straight up).
MAGNUM® tube diffusers are available with EPDM (FLEXNORM®) or silicone (FLEXSIL®) membranes. We offer a wide range of perforation patterns which can be selected in accordance with specific application requirements.
MAGNUM® tube diffusers are available in the standard effective lengths 1000 mm, 1500 mm and 2000mm (47,2", 66,9", 86,6").
Custom lengths and diffusers shortened on one side are available on request.
