Phresh Filter 315x500 mm

Phresh Filter 315 x 500 mm is a 12-inch activated-carbon canister for exhaust odour control in grow rooms and other ventilation setups. This variant matches 315 mm ducting and a 500 mm body length, with a rated maximum airflow of 1700 m³/h. The filter uses Phresh’s APEX triple-activated, virgin carbon and a 46 mm carbon bed with 51% open-area mesh to balance scrubbing efficiency and low pressure drop. A cone-shaped internal base helps distribute airflow evenly through the carbon bed. Aluminium top and base reduce weight, and D‑shackles make hanging easier. Thick fabric prefilters slide over the body, with spares supplied in the box. Pair with a compatible 12-inch extraction fan for effective odour and particulate removal.
