Kootenay Green Line 2500 for Large Grow Rooms
This filter scrubs odor, VOCs and other gaseous contaminants from the air in a large room or a 10-inch exhaust line. The canister measures 13.8 in across and 39.4 in long. Inside is a 2 in bed of screened, granular virgin activated carbon made from renewable resources. The carbon is machine packed, which keeps the bed even and the filter light for its size. The production process keeps carbon dust to a minimum. The filter is rated at a contact time of 0.05 seconds, the time air spends inside the carbon bed. Its maximum rating is 1471 CFM, or 2500 cubic meters per hour, in recirculating use. Run inline as an exhaust filter, the rating is 735 CFM. A 10 in flange comes fitted, so it connects directly to 10-inch ducting or a fan collar. A prefilter is installed at the factory to catch dust before it reaches the carbon. The filter tolerates operating temperatures up to 176°F. The whole unit weighs about 50.7 lb. The data sheet and brochure are attached.
Running a 10 Inch Carbon Filter as Exhaust or Scrubber
Decide first whether the filter will exhaust air out of the room or scrub and return it. For exhaust, size the inline fan to the lower inline rating once duct length and bends are counted. A 10-inch fan pulling air through the canister and out of the building is the common layout. For a scrubber, set the filter on the floor and mount a fan on top to pull room air through and blow it back in. Scrubbers handle odor between exhaust cycles and in sealed rooms with no outside venting. A canister this heavy needs ratchet hangers or a floor stand rather than tent poles. Seal the flange joint with a clamp and aluminum tape so all air passes through the carbon. Keep room humidity in check, because water vapor takes up space in the carbon that odor would otherwise use. Vacuum or replace the prefilter whenever it greys over with dust. That simple step protects the carbon bed and keeps airflow steady. Replace the filter once odor begins to pass through at the outlet. Check the hangers and duct joints at every changeover.
