Product Overview

The Heavy-Duty Steel Housing Inline Duct Fan is engineered to deliver reliable air movement, heat extraction, and odor management under high static pressure resistance. Built with a ceramic-coated steel casing and powered by a thermally protected AC motor, this inline blower is designed to operate against resistance from carbon filters, long ducting runs, and air distribution tees. Each unit comes with a tailored leather sound-dampening jacket to suppress casing vibrations and airflow noise, making it suitable for commercial grow facilities, hydroponic grow tents, building ventilation, and HVAC exhaust applications.

Key Performance Characteristics

  • Dual-Layer Noise Reduction: The external heavy-duty leather jacket wraps securely around the steel scroll body, attenuating high-frequency motor hum and structural resonance.
  • Corrosion-Proof Ceramic Coating: Tough ceramic powder coat seals the steel casing against high humidity, chemical sprays, and acidic indoor farming atmospheres.
  • Integrated Variable Speed Control: Inline step-less rotary controller provides continuous adjustment of fan speed, airflow rate, and noise output.
  • Stable Thermal Protection: Built-in automatic thermal cut-off resets safely if duct temperatures or electrical currents exceed critical thresholds.
  • Multi-Position Mounting: Included base mounting brackets and hardware support ceiling suspension, wall fixing, or horizontal floor mounting.
