RAM’s AirTECH 150/660 (6”) is a cylindrical activated-carbon exhaust filter designed for grow-room odour control and fan extraction systems. The model name denotes a 150 mm neck and 660 mm body length (≈6 in × 26 in). On the official size table it is paired with a maximum recommended fan flow of 1,150 m³/h. Construction features include machine-packed Australian carbon for consistent bed density, a washable pre-filter sleeve, and a rugged perforated Zintec steel shell; retailer technical listings state a 50 mm carbon bed. Part of the AirTECH range announced in June 2024, the 150/660 is commonly matched to 150 mm ducting and inline fans for small to mid-size tents.
