ECMF-315-S

TerraBloom’s ECMF-315-S is a silenced 12-inch EC inline duct fan built for high airflow with reduced noise. The insulated steel housing uses a 2-inch acoustic foam liner and internal suspension springs to cut sound output by roughly 10–15 dBA compared with the regular ECMF body. A brushless EC motor and dual jet-type impellers deliver up to 1,662 CFM (≈2,824 m³/h) at 268 W. The fan ships with a 0–100% digital speed controller and also accepts PWM and 0–10 V control via a 3.5 mm port. The unit carries IP64 ingress protection, is ETL listed, and its performance is independently tested with HVI certification. Four pre-installed hooks simplify hanging in grow rooms or HVAC runs. Duct connection outer diameter is 12.3 in (313 mm).
