RAM AirTECH HEAVY Filter 250/1000 (10") is a cylindrical carbon exhaust filter for grow-room odour control. With a 250 mm (10 inch) flange and 1000 mm body, it integrates into 250 mm ducting and is sized for high-capacity systems. The filter uses machine-packed Australian activated carbon inside rugged Zintec perforated mesh, with an Acoustafoam compaction ring and a washable pre-filter sleeve. RAM rates this 250/1000 model for a maximum recommended fan flow of 3100 m³/h. It is intended to sit on the extraction side of the ventilation circuit, scrubbing air before discharge. Pair with appropriately matched 250 mm inline fans and maintain the pre-filter to preserve airflow and service life.
