Our History
AJM Polyfilters Ltd was founded in 1974 by Martyn Walton, originally trading as AJM Filtration..
The business has steadily grown throughout the years and has been able to withstand recession where others have disappeared or merged in larger industrial conglomerates.
Since being involved in the Filtration Industry from the mid 1970’s, initially specialising with Filter Presses and rubber carrier belt type Horizonal Vacuum 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 it ultra low capital, operation and maintenance costs, along with unrivalled reliability.
Since its inception in 1994, which was based on an earlier expired Patent, the “POLYFILTER” vacuum belt filter has been developed and refined over the years and many of the early filters, now well over 25 years old, are still successfully operating 24 hours per day, 7 days per week with minimal operator involvement and maintenance. The only consumable item on the filter is the actual filter cloth.
Most companies operating the POLYFILTER Horizontal Vacuum Belt Filters spend more each year sevicing the Managing Directors car than they do on filter spares!
AJM Polyfilters Ltd are manufacturing the latest version of the POLYFILTER filter from modern manufacturing premises in West Yorkshire, England. Here we can carry out laboratory testing of your product. If, and when necessary, our Pilot Filter can be hired for longer trials at a clients own premises.
Historically and generally, the filter is operated completely by pneumatics making it ideally suited for ATEX Hazardous environments.
AJM Polyfilters continues to develop the filter and now with the introduction of alternative PLC control systems it can be integrated into most Siemens, Allen Bradley and Mitsubishi process controls.
