Ensuring effective heat extraction, continuous air exchange, and proper air quality management is critical in modern industrial manufacturing. We are pleased to announce the successful production, testing, and dispatch of a new batch of high-efficiency industrial roof exhaust fans (roof ventilators) designed for heavy-duty factory applications, chemical plants, and warehouse facilities.
Engineered for mounting directly on building rooftops, these specialized roof ventilation units act as the primary exhaust mechanism for extracting high-temperature air, moisture, airborne dust, and corrosive fumes, maintaining a safe and regulated environment inside large-scale industrial bays.
Technical Highlights of Our Industrial Roof Exhaust Fans
Our roof-mounted ventilators are built to withstand severe weather conditions and hostile industrial atmospheres while maintaining optimal energy efficiency:
Corrosion-Resistant Casing: Available in heavy-gauge hot-dip galvanized steel, stainless steel (SUS304/316), or chemical-resistant Fiberglass Reinforced Plastic (FRP/PVDF) for harsh chemical or seaside environments.
High Aerodynamic Efficiency: Dynamically balanced axial and backward-curved centrifugal impellers provide maximum airflow rates with low power consumption and minimal vibration.
Weatherproof & Rain-Proof Design: Equipped with a heavy-duty weather hood and integrated automatic gravity backdraft dampers to prevent rain, dust, and insects from entering when idling.
Explosion-Proof & VFD Options: Custom-fitted with ATEX/IECEx certified explosion-proof motors (EX d IIB/IIC) and variable frequency drive (VFD) compatibility for hazardous gas or dust environments.
Low Noise Operation: Built-in acoustic insulation linings and rubber vibration dampening mounts ensure compliance with strict workplace noise regulations.
Quality Assurance & Pre-Shipment Testing
Prior to shipment, every roof fan unit undergoes rigorous quality control inspections at our testing facility to meet global standards:
Dynamic Balance Calibration: Impellers are dynamic-balance tested to ISO 1940 standards to guarantee smooth, vibration-free long-term operation.
Motor Performance Checks: Full-load voltage, current, insulation resistance, and temperature rise testing under continuous load.
Acoustic & Airflow Testing: Air volume (m³/h) and static pressure (Pa) validation against project design specifications.
The units are packed in reinforced, moisture-proof export wooden crates to ensure safe transportation via sea container or overland truck transport to our overseas project sites.
