ECMF-150-S

TerraBloom’s ECMF-150-S is a 6-inch (150 mm) silenced EC inline duct fan built for installations where reduced noise is critical. A 2-inch acoustic foam layer inside a coated steel housing and a spring-suspended motor cut sound output by 10–15 dBA compared with the brand’s regular ECMF fans. The brushless EC motor delivers up to 288 CFM (about 489 m³/h) while drawing just 36 W at full speed. The package includes two wired controllers (analog dial and 8-speed digital), and the fan also accepts PWM and 0–10 V control via a 3.5 mm port. Rated IP64, HVI certified, and listed as ENERGY STAR Most Efficient (2021). Key dimensions: 21.5 × 9.6 in, with 6-inch duct connections; typical noise 31–50 dBA and static pressure 396 Pa.
