Window-Mountable FRP Exhaust Fan Greenhouse Airflow Management 800 Type (0.37kW)

Product Description

This wall-mounted belt-driven negative pressure fan is a corrosion-resistant industrial ventilation solution built with integral FRP (fiberglass reinforced plastic) casing, specially designed for factory workshops, shipyards, school buildings and public architectures. Adopting negative pressure suction ventilation principle, it generates strong and stable air extraction through aerodynamically optimized blades driven by a belt transmission system, rapidly exhausting indoor hot air, waste gas, dust, odor and moisture, and forcing fresh outdoor air to flow in for full air replacement.

The casing is integrally molded from high-quality SMC fiberglass, featuring excellent acid & alkali resistance, corrosion resistance, rust proof and anti-aging performance, perfectly adapting to harsh environments such as salt spray in shipyards, corrosive gases in chemical workshops and high humidity in breeding sites. Equipped with gravity self-closing louvers, it automatically seals the air opening when stopped to prevent backdraft, rainwater, dust and insects from entering. With standard wall-embedded installation size, it can be directly installed or replace old exhaust fans without major building modification. It is widely used for ventilation, cooling, dust extraction and dehumidification in industrial plants, shipbuilding yards, school buildings, warehouses and agricultural sites, providing a durable, efficient and energy-saving ventilation solution.

Applicable Locations

Industrial Manufacturing Workshops: Suitable for machinery processing, hardware manufacturing, electroplating, chemical and textile workshops. It quickly exhausts high-temperature waste gas, oil fume and corrosive dust, alleviates sultry working conditions and improves frontline staff comfort and production efficiency. Shipyards & Marine Engineering Sites: Ideal for shipbuilding workshops, hull operation areas and painting workshops. The FRP corrosion-resistant structure adapts to high humidity, salt spray and paint mist environments, effectively discharging welding fumes and organic exhaust gases. School Buildings & Public Venues: Perfect for classrooms, auditoriums, canteens and dormitories. It realizes overall air circulation and renewal in densely populated spaces, removes stuffy heat and peculiar smell, and maintains fresh and comfortable indoor air quality. Warehouses & Logistics Facilities: Suitable for storage warehouses, sorting centers and logistics yards. It expels excess moisture, musty odor and hot air to keep goods dry and prevent deterioration, while improving on-site working comfort. Agricultural Breeding & Greenhouses: Applicable to livestock and poultry houses and vegetable greenhouses. It discharges ammonia gas and humid air, improves breeding and growing environment, and reduces the incidence of animal and crop diseases. Construction & Decoration Sites: Suitable for temporary construction sites and decoration operation areas. It quickly discharges dust and paint fumes, improves the working environment and protects the health of on-site operators.

Fan Parameters

Feature

High Efficiency Negative Pressure Ventilation: Adopts aerodynamically optimized large-inclination blades matched with belt deceleration transmission system to generate strong and stable negative pressure suction. It quickly forms indoor negative pressure field 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. FRP Anti-corrosion Casing: The whole machine shell is integrally molded by SMC fiberglass with anti-corrosion and anti-UV formula, featuring acid & alkali resistance, salt spray resistance, rust proof and aging resistance. It adapts to harsh corrosive environments such as shipyards and chemical workshops, with service life 2–3 times that of ordinary metal fans. Belt Drive Stable Operation: High-quality V-belt transmission with adjustable tension design, running smoothly with low noise and small vibration. The belt transmission reduces motor rotating speed to match the optimal blade working condition, improving air volume efficiency and extending motor service life. Automatic Louver Protection: Equipped with gravity self-closing louver structure, which automatically opens with airflow when the fan starts and automatically closes when the fan stops. It effectively prevents rainwater, dust and insects from flowing back into the room, without additional electric control. Industrial-grade Durable Motor: Fully enclosed pure copper core motor with built-in thermal overload protection, dust-proof and moisture-proof. It maintains stable operation for a long time in harsh industrial environments, with low failure rate and long service life.

Advantages

Excellent Corrosion Resistance: Integral fiberglass casing is rust-free, acid and alkali resistant, and salt spray resistant. It is far more durable than traditional galvanized steel fans in corrosive environments such as shipyards, electroplating workshops and chemical plants, with a service life of more than 10 years. High Efficiency & Energy Saving: Belt drive matching optimized blade design delivers large air volume with low power consumption. Compared with traditional metal exhaust fans of the same specification, it saves more than 30% of electricity, with extremely low daily operating cost and short investment return period. Low Noise & Stable Operation: Belt deceleration transmission + dynamic balance calibrated blades greatly reduce operation vibration and noise. It runs stably with low noise, and will not interfere with normal work, teaching and office activities, suitable for installation in schools, office buildings and densely populated venues. Convenient Wall Installation: Standard square embedded wall-mounted design matches conventional wall opening sizes. It can be directly installed or replace old exhaust fans without complex building renovation, with simple and fast installation process and short on-site construction period. Low Maintenance Cost: Detachable protective grille and blades are easy to disassemble for daily dust cleaning. The belt tension adjustment structure is convenient for routine maintenance. The whole machine has stable structure with few wearing parts, no professional technicians are needed for daily maintenance, and the long-term operation and maintenance cost is extremely low. Wide Scenario Adaptability: Two standard models match different space sizes and ventilation demands. It is widely applicable to industrial workshops, shipyards, schools, warehouses, breeding and other scenarios, and can provide targeted configuration solutions according to environmental corrosion degree and ventilation requirements.
