Discfuser® Coarse Bubble Diffuser

Discfuser® diffusers are recommended for applications where you have or expect high solids concentration in the aerated liquor.

The Discfuser® diffuser consists of three components:

an ABS housing
a stainless steel retaining ring
a PVC movable disc.

The movable disc is inserted between the diffuser housing and the stainless steel retaining ring, and is free to rise and fall within the space provided between the housing and the retaining ring. As air is discharged through the diffuser, the disc rises and air is permitted to pass around the entire periphery of the diffuser into the liquid.

Features and Benefits

If the air supply is interrupted, the hydrostatic pressure of the liquid above the diffuser will force the disc against the diffuser housing preventing the passage of liquor into the air supply piping.
Available with control orifices in five diameters. Proper selection ensures uniform air distribution throughout the tank contents, while optimizing the head loss through the system.
