Magnum Membrane Tube Air Diffusers

OTT MAGNUM® Diffusers – Patented Technology for Rapid Installation

Membrane type:
FLEXSIL^®
FLEXNORM^®

Clamps

Crimped Stainless Steel clamps at both ends of the membrane to ensure leak-proof operation.
Membrane

FLEXNORM^® and FLEXSIL^® membranes are optimally tailored to domestic and industrial wastewater (STP and ETP) applications.
Their consistently high performance and reliability are ensured by highest quality standards and stringent QC checks. Each diffuser carries a printed lot number for QA traceability.
Fold-free Membrane

OTT diffuser support tubes come with a patented ridge / geometric shape on the top which prevents folding / wrinkling of the membrane when air supply stops leading to an improved life of the membrane. This unique detail is the basis for a high degree of mechanical safety and durability of membranes.
Perforation

Precisely engineered perforation delivers uniform air release and excellent bubble pattern. This clearly sets us apart from competitors – as demonstrated by numerous trials conducted by independent institutions across the world.
PP Support Tube

Single piece injection moulded support tube made of eco-friendly, fully recyclable polypropylene (PP). It’s uniquely designed shape and construction provide a sturdy support to the membranes and other unique benefits.
CLIP IN^® Connection

The unique diffuser connection using CLIP IN^® locking bolt assembly facilitates quick installation of the diffusers. One person can install 6 diffusers per minute! Makes the MAGNUM^® the easiest to install tube diffuser on the market.
Dedicated Air Channel

The unique singe piece injection moulded structure of the support tube of the MAGNUM^® makes it possible to provide an air channel at the bottom of the tube which ensures a uniform distribution of air along the length of the diffuser.
This helps achieve a consistent bubble pattern along the length of the diffuser even with low quantities of air, giving a clear edge over competitor products.
Flooded chamber

The support tube of the MAGNUM^® diffuser is open at the ends and at the centre leading to minimum buoyancy of the diffuser.

Air diffuser for wastewater treatment plant

Aeration tank with Magnum^® 2000 Membrane tube air diffusers with FLEXSIL^® membranes

OTT MAGNUM^® tube air diffusers consist of single piece injection moulded polypropylene support tubes surrounded by membrane sleeves which are kept in position by stainless steel clamps.

The design of the membrane sleeve prohibits clogging of the pores which are self closing when air flow stops.

The air distribution channel extending over the effective length guarantees an even distribution of air.

OTT MAGNUM^® tube air diffusers are available in standard effective lengths of 1000 mm, 1500 mm and 2000mm with EPDM (FLEXNORM^®) or Silicone based rubber (FLEXSIL^®) membranes.

MAGNUM^® diffusers can be installed on 80NB/90OD pipes with 38(+0.5/-0.0)mm diameter holes. Their CLIPIN® connectors facilitate quick installation.

OTT MAGNUM® diffusers are available with a wide range of perforations:

OTT MAGNUM® HE (High Efficiency) diffusers [High Efficiency Systems]

come with 0.6mm perforations with a special perforation pattern and with an air throughput range from 1 – 6 Sm3/hr/mtr(diffuser length) are used for application in Aeration tanks which require very high energy efficiency. Due to the need of higher life these are available only in Silicone based rubber (FLEXSIL®) membranes.

OTT MAGNUM® Fine Bubble diffusers

come with 1mm perforations with an air throughput range from 2 – 12 Sm3/hr/mtr(diffuser length) are primarily used in Aeration tanks.

OTT MAGNUM® Coarse Bubble diffusers

come with 2mm perforations with an air throughput range from 4 – 24 Sm3/hr/mtr(diffuser length) are used in Equalization tanks for mixing and stripping.
