Description
Some grease trap manufacturers recommend installing a vessel vent to be vented to the atmosphere. Installers often skip this vent for ease of installation, allowing odors to escape the grease trap and invade the kitchen. The Big Dipper Carbon Vent Filter is the only filter of its kind in the industry, trapping odors while letting fresh air out of these vents.
Big Dipper Carbon Vent Filters fit snugly into any 2-in. no-hub coupling or adapter. Each filter contains 9 oz. of activated carbon pellets, the same material proven in other odor-prevention applications, including filtering residential HVAC systems.
Carbon is “activated” by injecting it with hot air or steam, creating pores that trap odor molecules. Activated carbon has more surface area to trap odor molecules than regular carbon. Big Dipper Carbon Vent Filter containers are durable and reusable, and the carbon pellets are biodegradable. Each filter comes with one 9-oz. packet of replacement pellets.
Additional Carbon Vent Pellets are currently sold in packs of 4.
