Suction belt filter HSF CON

Suction belt filter HSF CON

HOFFMANN Suction Belt Filters HSF CON are used for filtering CL during high precision surface grinding. The high filtration grade renders HOFFMANN Suction Belt Filters ideal, among others, for grinding of gears e.g. in the automotive, wind energy, mining and shipbuilding sectors. Optionally, the HSF CON can also be designed for operation with filter fleece(HSF CON-V). The HSF CON is particularly suitable if you want to process different materials that require a change between filter fleece and plastic endless belt.
