Vertical pressure leaf filter VERSIS

Amafilter – LFC Lochem (Filtration Group Process Systems) VERSIS pressure leaf filter is a vertical pressure filter with a large specific filtration area due to the shape of the filter elements. We have been building these filters for more than 60 years.

The VERSIS range incorporates several product improvements making the design state of the art. More than 10000 vertical and horizontal pressure leaf filters have been sold worldwide for various applications so far.

The double sided filter leaves are made from stainless steel. The rigid filter leaves have five layers of stainless steel wire screen. The top layer of screen depends on the application. The filter leaves are individually mounted on the central manifold, which allows the removal of any or all of the filter leaves easily and quickly. The filter cake can be dried with compressed air, inert gas or steam. The cake is discharged by a pneumatic vibrator, through a large butterfly valve.

Pressure leaf system advantages

The Versis pressure leaf filter is an enclosed filtration system and can be fully automated. This filter produces a high filtrate clarity after the clarification run and is also suitable for all kinds of filter aids. The regeneration time between the filtration cycles is short. The vertical filters require only a small footprint and are standard equipped with a cover lift assembly. The design of the pressure leaf filter keeps maintenance to a minimum. These advantages result in an economical filtration solution.

LFC Lochem

In 1979, three employees of Machine Factory Arnhem in the Netherlands started their own company to manufacture pressure leaf filters and named the company “Liquid Filtration Consultants“ or “LFC Lochem®”. The company quickly gained an outstanding reputation as an innovative engineering and manufacturing company that specialized in liquid filtration technology. Over the years, LFC Lochem® developed and perfected many filtration products. This resulted in a high quality, comprehensive standard range for widely diverging industries.
