Phresh Carbon Filter 100x300 mm

Phresh Carbon Filter 100x300mm is a compact exhaust canister for odour control and particulate scrubbing in small grow spaces. The 100 mm flange pairs with 4 inch ducting and extraction fans; the 300 mm body is filled with triple‑activated, virgin APEX carbon and a 46 mm bed depth to maximize contact time while minimizing pressure drop. The perforated shell uses a 51% open-area mesh and a conical internal base to promote even airflow through the carbon. Pre-filter sleeves are supplied, and D‑shackles on the top plate simplify hanging. This size is factory rated at 340 m³/h, making it a fit for typical 4 inch fans or modest negative‑pressure tents when matched appropriately.
