Description

Dormont WD-20-A Semi-Automatic Draw-Off Grease Interceptor

20 GPM flow rate • 40 lb grease capacity • 3" threaded inlet & outlet

Keep plumbing lines clean while reducing pump-out costs. The WD-20-A combines Dormont’s proven baffle design with a convenient semi-automatic draw-off system, letting you remove liquefied grease through a hose and shut-off valve—no heavy lids, no messy buckets, and far less downtime for your staff.

Key features & benefits

  • 20 gallon-per-minute flow rating handles small to mid-size pot, pan, scullery and prep sinks.
  • 40 lb grease storage capacity meets or exceeds most local code requirements for fixtures of similar flow.
  • Semi-automatic draw-off system:
    • Internal stainless steel flow-control fitting slows incoming waste for optimal separation.
    • Flexible draw-off hose with line shut-off valve lets staff evacuate floating grease directly to a container.
  • Rugged 11-ga cold-rolled steel body with oven-cured, acid-resistant epoxy coating—inside and out—for long service life.
  • Gasketed checker-plate steel cover secured by hex-head perimeter bolts for a positive, non-slip seal.
  • Removable grease-accumulating cover & baffle assembly simplifies full clean-outs.
  • Deep-seal trap with clean-out plug prevents sewer gas carry-over.
  • 3" FNPT threaded inlet and outlet for fast, leak-free pipe connections.
  • Installs on the floor or recessed in slab; no external flow restrictor required.
