A diffuser suitable for aeration and agitation processes in treating the waste water of a plant, etc.
Leaf Spring Diffuser integrates a unique stainless steel leaf spring for highly efficient oxygen absorption, made possible by the air chopping effect.
Vibrations of the leaf spring generate micro-bubbles that make it possible to stably keep the oxygen absorption efficiency at 9% for a long period.
- * Type 1, Type 3, Type 6, etc. are available depending on the application and air level.
- Can be operated without maintenance for several years because no clogging occurs.
- Possible to reduce installation cost and initial investment because no blower air filter is required.
Line-up and installation example
Type 1 diffuser has a single leaf spring. The main unit is made of ABS resin with excellent shock resistance and heat resistance.
Aeration level is 110-340 L/min. It has connection ports of a female screw for a 3/4B pipe. Type 1 is normally used for a small-size aeration system or as a replacement for other diffuser types.
Type 3 is comprised of a stainless steel square pipe with sides of approx. 40 mm and three leaf springs. The aeration level is 170-1700 L/min.
Connection port has a 3/4B female screw or 1B male screw. This type is used for various kinds of aeration systems.
Type 6 is a stainless steel diffuser with six leaf springs. The aeration level is 340-3400 L/min.
Connection is conducted via a center flange by using four bolts. Type 6 forms a wideband diffusion pattern. This type is designed to be installed on an air header fitted on an aeration tank floor or on a drop pipe.
