Schenck Process offers a 3-A approved Hygienic Round Top Removal (HRT) Filter designed for sanitary applications where dust collection is required in low-capacity pneumatic conveying systems such as vacuum loading of extruders or refilling minor/micro hoppers. This circular bodied pulse jet filter features a top hinged dome.

Schenck Process offers HRT filter in two styles. Without the hopper (Style II) the filter is suited as a bin vent filter for storage tanks, work bins and surge hoppers. With a 60° hopper (Style III) the filter receives dust through the hopper inlet and discharges the collected dust through an airlock for dust disposal or recycling. When fitted with a pneumatic receiver, the Schenck Process HRT filter becomes a product receiver. Product enters the filter and is discharged from the bottom through an airlock. Centrifugal force separates the product from the airstream and gently discharges it.

Other features of the HRT 3-A Filter include:

• Interior and exterior finishes meet 3-A requirements
• Ferrules mounted for use with clean-in-place (CIP) skid and with clean-out-of-place (COP) filter media and purge pipes
• Diaphragm bodies are all stainless steel
• Bag cages: 304 stainless steel
• Bags: 16 oz. singed polyester, top removal (meets 3-A requirements)
• Spring assisted hinge for clean air plenum access
