Valmet selected PFMG-10 filter from ITK Envifront for lathe dust extraction

To handle lathe dust extraction, Valmet selected ITK Envifront as filter supplier. Valmet has purchased a PFMG-10 cassette filter, providing very high performance and low pressure drop. The intelligent CPFE control system and a cyclone were delivered in combination with the PFMG-10 filter. With CPFE, Valmet has full control over filter status using patented algorithms saving compressed air, reducing wear on filter media, and providing better emission values.

The ITK Envifront cassette filter PFMG-10 is capable of handling very low emission requirements while providing high availability. The filter design prevents wear and clogging of the filter cloth, resulting in low energy consumption and long maintenance intervals.

CPFE uses true filtration resistance control. With the help of patented algorithms and embedded sensors, CPFE can calculate the actual filter resistance and control the compressed air purge based on the actual filter condition instead of time interval or simple differential pressure. This leads to fewer cleaning cycles and a better filter functionality, savings in compressed air consumption, less wear of filter media and lower emissions. CPFE also provides remote support capabilities and improved process understanding for each unique filter installation.
