Rotary Filter

Rotary Filter

The Sinclair Rotary is a non-pressurized gravity filter in which the liquid is distributed inside a slowly rotating drum.

Particles in the liquid are retained on the inside of the screen covering the drum and are carried upwards and over a trough within the drum where the particles are washed off by an external shower pipe into the reject trough.

The filtered water is collected in a vat beneath the drum and the collected particles are carried out from the drum by means of piping connected to the particle collection trough.
