Hopper venting filter for efficient dust filtration
When storing materials in intermediate or weigh hoppers, preventing dust emissions is essential for maintaining air quality and safety standards. This is particularly true in industries dealing with potentially explosive materials where traditional venting systems may not suffice.

Ensures low emissions and efficient venting
The HOPPERJET from WAMGROUP is a compact, polygonally shaped venting filter designed for installation on hoppers. Utilizing advanced dust filtration technology, it features a POLYPLEAT or bag-type filter element that efficiently separates dust from the air stream. An integrated automatic reverse air jet cleaning system ensures that dust accumulated on the filter drops back into the hopper. HOPPERJET achieves high filtration efficiency with low emission values, making it suitable for industries ranging from food processing to heavy industries. Available in variants certified for use in potentially explosive atmospheres according to the ATEX directive, the HOPPERJET offers versatile applications with easy maintenance and retrofitting.
