About us
Company Profile
After being involved in the filter industry from the mid 1970’s, specialising with filter presses and rubber carrier belt filters “Polyfilters” was formed by Martyn Walton in 1994. since which time the “Polyfilter” has been developed into the world’s leading solution for Horizontal Vacuum Belt Filters, giving ultra low capital, operation and maintenance costs, along with unrivalled reliability.
The POLYFILTER Horizontal Process Filter is probably the most versatile filter in the marketplace today. If your product, or effluent sludge, can be filtered in the laboratory on a Buchner filter, it can be filtered on the plant with the POLYFILTER Horizontal Process Filter.
The POLYFILTER has been developed and refined over the years and many of the filters are over 25 years old and still operating 24/7 with minimal maintenance. The only consumable on the filter is the actual filter cloth.
AJM Polyfilters Ltd are manufacturing the latest version of the POLYFILTER filter from modern Manufacturing premises in West Yorkshire, along with a fully developed laboratory housing our pilot filter which is available for trials at our premises. Alternatively, we can rent our Pilot filter for longer trials at our customers facilities.
AJM Polyfilters Ltd continues to develop the process, with the introduction of Siemens Control systems where requested. This can be integrated with most Siemens process controls. We also offer Allen Bradley and Mitsubishi controls.
Generally, the filter is operated by pneumatics and is suitable for ATEX and other safe zones.
