TerraBloom’s MFIF-6 is a 6-inch inline duct fan designed for exhaust or intake in grow tents, attics and basements. The AC motor draws 70 W and delivers up to 395 CFM, controlled by a built‑in variable speed controller that can reduce output to about 50% for quieter operation. The ABS housing keeps weight to 5.5 lb, and an included mounting bracket indicates airflow direction for correct installation. Dimensions are 11.5 x 8 x 8 inches, with 6-inch duct connections. The unit is ETL certified and rated around 2400 RPM at full speed. TerraBloom recommends pulling through carbon filters up to 6 x 20 inches and minimizing elbows to preserve airflow. Equivalent airflow is approximately 671 m³/h.
