Contra-Shear® Inclined Rotary Screen

The Contra-Shear inclined rotary screen (IRS) is installed at an angle of 35 degrees and is used for fine screening of sewage and industrial effluent where screening and solid extraction ability is desired within a single unit. The screen drum is constructed out of Vee-Wire^®; however, perforated plate and mesh designs are also offered. The IRS can be installed either directly in the channel or in a separate tank.

An automatic spray system comprising of two pipes with nozzles operates when the screen drum rotates and keeps the drum clean.

The IRS is capable of handling flow rates from 1,188 gpm / 270 m³/hr to 20,253 gpm / 4,600 m³/hr through a single unit. Slot sizes range from 0.02 in. / 0.5 mm to 0.24 in. / 6 mm on the Vee-Wire models and 0.08 in. / 2 mm upwards on the perforated plate and mesh models.
