Specialized Ventilation for High-Humidity Environments

The Dehumidifier Roof Fan is a purpose-built ventilation unit engineered to tackle the unique challenges of moisture-laden air. Its core mission is to efficiently remove water vapor from indoor spaces, preventing condensation, inhibiting mold growth, and protecting structural integrity from corrosion. This specialized dehumidifier roof fan is indispensable in environments with saturated air, such as paper mills, food processing plants, indoor swimming pools, and underground parking garages, where standard ventilation is insufficient.

Corrosion-Resistant Construction for Demanding Duty

Designed to comply with AMCA 260 standards, this products delivers an airflow range of 8,000 to 20,000 m³/h, capable of overcoming resistances from 50 to 200 Pa in short duct runs. It operates with a total efficiency of 50–60%, utilizing 2.2–7.5 kW of power. To withstand constant exposure to moisture, key components like the impeller and housing are constructed from stainless steel or all-fiberglass materials. It is driven by a fully enclosed, moisture-proof outdoor motor (3.0–11.0 kW, 380V/50Hz, IP55, F/H-class insulation, IE3). Operating at approximately 1450 r/min, it maintains a noise level below 70 dB(A) at 3 meters, with G6.3 balancing ensuring smooth operation and vibration under 2.8 mm/s.

Built to Endure Moisture and the Elements

The dehumidifier roof fan is fortified for both outdoor exposure and high-humidity duty. It features Grade 10 wind resistance and IPX4 rain protection. As a standard, it includes a corrosion-resistant gravity backdraft damper and is equipped with a specialized sealing and insulation structure designed to prevent both water ingress and surface condensation. For safety, it meets standard lightning protection requirements with integrated grounding terminals, and its corrosion-resistant design complies with seismic standards for 8-degree fortification intensity. This robust build guarantees long-term, reliable performance in the most demanding damp environments.
