DE Parts, Felt Collars - 30" x 36", 38" x 48", 30" x 60"

Felt collars for commercial vacuum DE filter leaves (covering frame sizes 30" × 36", 38" × 48", and 30" × 60") are high-density, chemical-resistant synthetic or wool-blend compression gaskets engineered to provide a tight seal between the leaf outlet stems and the vacuum collection manifold. By compressing firmly into the header sockets under negative suction pressure, they prevent raw diatomaceous earth powder and debris from bypassing the filter grid and returning to the pool. Because these components are lightweight, fabric-based sleeves, individual collars typically weigh under 0.25 to 0.5 lbs each. When packaged for commercial distribution or full-grid replacement, standard multi-pack sets (typically 10 to 24 collars per box) have a total shipping weight of approximately 2 to 5 lbs (0.9 to 2.3 kg) in a compact corrugated carton.

When replacing these collars alongside whole leaf grids, shipping weights scale according to the frame assembly: a boxed 30" × 36" replacement leaf typically ships at 14 to 18 lbs (6.4 to 8.2 kg), a 38" × 48" leaf ships at 22 to 28 lbs (10.0 to 12.7 kg), and an extended 30" × 60" leaf ships at 24 to 30 lbs (10.9 to 13.6 kg). Proper installation requires pressing each collar squarely against the stem shoulder and verifying that no cloud of DE enters the pump strainer pot or return line during the initial pre-coat cycle.
