Hygienic Round Top Removal (HRT) Filter
Industrial pulse jet dust collector for food processing

Pulse jet dust collector HRT filter
for low-capacity pneumatic conveying systems
HRT filters are industrial pulse jet dust collectors for low-capacity pneumatic conveying systems, such as vacuum loading extruders, refilling minor or micro hoppers, and bin venting. Additionally, because they are designed for low air volumes, the HRT can handle higher pressures than square or rectangular units.
The circular-bodied filter features a top-hinged dome for easy access. Top-removal snap band filter bags require no tools and can be quickly changed, simplifying maintenance while maintaining hygienic stainless steel construction.
Coperion offers the HRT filter in two styles:
- Style II (without hopper): Ideal as a bin vent filter for storage tanks, work bins, and surge hoppers.
- Style III (60° hopper): Receives dust through the hopper inlet and discharges collected dust through an airlock for disposal or recycling.
When fitted with a pneumatic receiver, the HRT filter becomes an efficient product receiver. Centrifugal force separates the product from the airstream, gently discharging it through the bottom airlock.
