It features a two‑speed AC motor, high‑quality plastic housing, and a removable central body for easy cleaning and installation. On high speed the TT 150 is rated at 252 CFM free air (about 428 m³/h), with a built‑in high/low switch and included mounting plate and power cord. The fan is compatible with 120 V/60 Hz circuits, uses ball bearings for long service life, and carries IPX4 protection. Typical applications include utility rooms, grow tents, and general HVAC boosting where a compact 150 mm (6 in) fan is required.
