CarboAir 50 315x1200mm is a granular-activated carbon exhaust filter for high-capacity odour and VOC control in grow rooms. With a 315 mm flange and 1200 mm body, it uses a 50 mm carbon bed and is rated up to 3850 m³/h when correctly matched to a suitable fan. The cylindrical metal mesh housing maximises airflow while maintaining contact time for effective adsorption. Each filter ships with a machine-washable pre-filter to trap dust and extend service life. CarboAir filters are laboratory tested with Systemair fans and are commonly paired with RVK models; install on the intake side of the extractor fan inside the room. This size suits demanding extraction setups that require low restriction and reliable, consistent performance over long cycles.
