High-Power Wall-Mounted Industrial Fan – High-Velocity Airflow For Factory Workshops

Product Description

This heavy-duty negative pressure wall-mounted industrial fan is a high-performance square-type ventilation equipment engineered for large-space air exchange, fume extraction, dust removal and cooling. Adopting aerodynamically optimized blades and 100% copper-core industrial motor, it generates strong suction with large airflow volume, rapidly extracting stale air, high-temperature fumes, dust and odors indoors to create a negative pressure environment, which naturally draws fresh outdoor air in for full-area air renewal. Equipped with gravity self-closing shutters, it automatically seals the opening when the fan stops to prevent backdraft, rainwater, dust and insects from entering. Constructed with thickened galvanized steel frame and reinforced protective grille, it is shock-resistant, corrosion-resistant and suitable for long-term continuous operation. Designed for wall opening installation without occupying floor space, it is widely applied in factory workshops, retail stores, school buildings, churches, warehouses and public architectures, delivering a cost-effective and reliable ventilation solution.

Applicable Locations

Factory & Production Workshops: Suitable for machinery processing, hardware manufacturing, textile printing and welding workshops, rapidly exhausting high-temperature waste gas, oil fume and dust, alleviating sultry working conditions and improving frontline staff comfort and production efficiency. Shops & Commercial Premises: Ideal for supermarkets, convenience stores, catering outlets and retail shops, removing indoor odors and stuffy air while introducing fresh air to maintain a comfortable shopping and dining environment. Schools & Public Buildings: Perfect for classrooms, dormitories, offices and public facilities, realizing whole-room air circulation and renewal, keeping indoor air fresh and reducing stuffiness in crowded enclosed spaces. Churches & Large Venues: Adapted to churches, auditoriums, assembly halls and other tall open spaces, large-range negative pressure extraction promotes overall air circulation and solves air turbidity problems in densely populated venues. Warehouses & Logistics Facilities: Suitable for storage warehouses, sorting centers and logistics parks, expelling excess moisture, musty odors and hot air to keep goods dry and prevent deterioration, while improving on-site working comfort. Kitchens & Processing Workshops: Applicable to commercial kitchens, food processing plants and baking workshops, quickly removing oil fumes, steam and peculiar smells to maintain a clean and hygienic working environment.

Fan Parameters

Feature

High Efficiency: Adopts aerodynamically optimized large-inclination blades and widened air duct structure, delivering strong negative pressure suction and large airflow volume. It quickly forms indoor negative pressure to realize rapid full-space air exchange, effectively exhausting high-temperature fumes, dust and odors with no dead corners, achieving excellent ventilation and cooling effect. Automatic Restart Function: Built-in power-off memory module automatically restores previous operation status once power supply is restored after an outage. No manual reset is required, perfectly adapting to unattended industrial workshops and public building scenarios. Electronic Control System: Equipped with industrial-grade fully enclosed copper motor with built-in thermal overload protection circuit, which automatically cuts off power in case of overheating to ensure safe long-term operation. Optional multi-speed control switch supports flexible adjustment of airflow intensity. Modular Design: Standardized overall dimensions match universal wall opening sizes, compatible with most existing exhaust fan openings for direct replacement. The detachable protective grille and blades are convenient for disassembly, cleaning and parts replacement, reducing daily maintenance difficulty. Advanced Airflow Technology: Adopts negative pressure ventilation principle with optimized blade angle and air duct curve, reducing airflow turbulence and noise while enhancing suction efficiency. The gravity self-closing louver structure realizes automatic opening and closing with fan operation, integrating efficient ventilation with rainproof, windproof and insect-proof functions.

Advantages

High Ventilation Efficiency: High negative pressure suction with large airflow achieves rapid overall air replacement in enclosed spaces, with ventilation efficiency over 60% higher than ordinary wall fans. It quickly eliminates indoor sultriness, odors and dust, delivering uniform dead-end-free ventilation effect across large areas. Energy Efficiency: High-efficiency pure copper motor matched with aerodynamically optimized blades delivers strong exhaust capacity with low power consumption. Compared with traditional ventilation equipment of the same effect, it reduces electricity consumption by more than 30%, with outstanding energy-saving effect and low daily operating cost. Durable Design: Thickened galvanized steel casing with anti-corrosion treatment, high-strength steel blades and fully enclosed dust-proof motor adapt to harsh industrial environments with high temperature, dust and humidity. Built-in motor overheat protection ensures stable performance, low failure rate and service life of more than 10 years. Rapid Installation: Standard embedded wall-mounted design fits standard wall opening sizes, can be directly installed or replace old exhaust fans without complex building renovation. The installation process is simple and fast, greatly shortening on-site construction and commissioning time. Low Maintenance Requirements: Detachable metal protective grille and blades are easy to disassemble for daily dust cleaning. The structure is stable and reliable with few wearing parts, no professional technicians are needed for daily maintenance, and the long-term operation and maintenance cost is extremely low. Versatile Compatibility: Multiple size and power models are available to adapt to spaces of different scales. It is widely applicable to factory workshops, retail stores, school buildings, churches, warehouses and other scenarios, meeting various demands of ventilation, cooling, dehumidification and dust extraction.
