WAM Hopper Jet Venting Filters

HOPPERJET is a compact venting filter for mechanically filled hoppers.
Dust is separated from the air flow by a single POLYPLEAT or bag-type filter element and drops back into the hopper after an integrated automatic reverse air jet cleaning system inside the weather protection cover has removed the dust particles from the filter elements.
