The Ventmatic Series Rotary Valve Venting Filter Range is a compact carbon steel painted, twin cartridge reverse jet cleaning venting filter with optional integral fan. It is designed primarily for rotary valve venting applications, but is also equally well suited for other low duty venting applications.

Its two valve cleaning system ensures 50% ‘free’ vent area during cleaning and can therefore be used in applications where ‘on- line’ cleaning (cleaning during operation) is required, or where pressurisation of the filter chamber and associated discharge equipment could cause other process problems.

The optional fan gives ‘forced aspiration’ to the unit to negate positive pressure in the filter chamber.
