Diffuser PEARLCOMB

Disk type membrane

Superfine air bubble diffuserDisk type membrane

The high oxygen transfer efficiency is acquired by generating ultrafine bubble. Since the holes on the membrane close when operation is stopped, back flow of dirty water is prevented, and there is no clogging.

Characteristics of disk type membrane

High oxygen transfer efficiency, low pressure loss

High oxygen transfer efficiency, low pressure loss
Since ultrafine bubbles are supplied into the liquid from a lot of pores in the diffuser plate, high oxygen transfer efficiency is acquired. In addition, low pressure loss (air-flow resistance) is realized with the product by using flexible material.

Flexible layout is possible.

Flexible layout is possible.
It is possible to install flexibly according to the form of the place of installation.
