Delivering vacuum filtration to the highest levels of performance since 1869. 

Established in 1869 near Lyon in France, FILTRES VERNAY product range symbolises the success of an industrial adventure, the author of major innovations like VERNAY rotary drum filter. 

It takes pride in providing a range of filtration solutions that have occasionally contributed to significant inventions like the vacuum drum filter in 1910.  

VERNAY rotary drum vacuum filter has been developed for continuous industrial processes with liquid/solid separation. 

The rotary drum filter is a reliable and versatile filter that is widely used in the food and chemical process industries. It consists of a rotating drum that is immersed in a trough filled with slurry. When differential pressure is applied, the slurry is drawn through the filter cloth on the drum, leaving behind a cake of solids. The cake is then removed from the drum and the process is repeated.

This drum is divided into 2 independent sectors, sealed from each other and covered with a filter cloth. Each sector is connected by piping to the vacuum “distributor” head. During rotation, the solid-liquid separation takes place in the submerged part, and the solid is washed and dewatered before being discharged.
