Heavy-Duty Steel Construction: Rugged steel housing protected by a durable, corrosion-resistant ceramic-coated finish for industrial and indoor cultivation environments.
Acoustic Noise & Vibration Dampening: Includes a custom-fitted external leather acoustic jacket to minimize motor resonance, housing vibration, and operating decibels.
High Static Pressure Airflow: Powerful backward-curved centrifugal impeller delivering 171 CFM to 1,060 CFM (290 to 1,800 CMH) across 4-inch to 12-inch duct diameters.
Thermally Protected AC Motor: High-efficiency motor equipped with internal thermal overload protection for safe, non-stop 24/7 continuous duty.
Dual Voltage Configurations: Available in both 120V / 60Hz (North America) and 230V / 50Hz (Europe / UK / Australia / Global) electrical standards.
Plug & Play Installation: Comes standard with a 180 cm (6 ft) pre-wired power cord, variable speed dial controller, and heavy-duty steel mounting brackets.
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.
