Product Details
Product Overview:
The louver-type ventilation fan (wall-mounted louver exhaust fan) is a square, axial-flow ventilation device featuring an ABS flame-retardant plastic housing and an automatic opening‑and‑closing louver mechanism. When powered on, the louvers automatically open to exhaust air; when power is off, they close under their own weight, effectively preventing outdoor insects, rain, and cold drafts from entering. By rotating its axial‑flow impeller, the fan creates negative pressure, swiftly removing moisture, odors, cooking fumes, and stale air. It offers quiet operation, energy efficiency, dust and rain protection, easy installation, and automatic wind‑blocking functionality. Available in a 220V single-phase household version and a high‑power industrial model, it is widely used for ventilation in kitchens, bathrooms, small shops, warehouses, and other spaces.
Core Advantages of the Products:
Automatic louvered windscreen: When the shutter is closed, it blocks rain, insects, and the backflow of outdoor cold air, eliminating the need for an additional wind- and rain‑proof cover.
Low noise and energy-saving: Fully enclosed ball-bearing motor, with low power consumption, smooth operation, and minimal noise; energy-efficient and durable for long-term use.
Corrosion and moisture resistance: The entire unit features a plastic housing that is waterproof and moisture‑resistant, making it highly resistant to rust and degradation even in the humid environments of kitchens and bathrooms.
Easy installation: Wall‑mounted installation with wall‑mounted brackets; the square design fits standard pre‑drilled wall openings, and disassembly, installation, and maintenance are straightforward.

Material distinction
Standard model: ABS plastic body; a standard household kitchen and bathroom fixture, offering excellent value for money and superior water resistance and moisture durability.
Industrial anti-corrosion model: FRP/stainless steel body—suitable for chemical and humid workshops, resistant to acid and alkali corrosion.
Applicable use cases:
1. Residential Home Scenario
Ventilation in the bathroom and shower removes moisture and odors; the kitchen provides basic fume extraction; the balcony and storage room offer ventilation to reduce dampness; and the bedroom and walk-in closet ensure air exchange to eliminate stuffy smells.
2. Commercial Storefront Scenarios
Wall-mounted ventilation for convenience stores, bubble tea shops, hair salons, and small retail outlets, effectively removing indoor heat, cooking fumes, and unpleasant odors; also provides auxiliary exhaust ventilation in the kitchens of small food-service establishments.
3. Agricultural Product Warehousing Scenario
Moisture control and ventilation for small warehouses and utility rooms; ventilation, odor removal, and humidity reduction in rural poultry pens.
4. Special Scenarios in Factory Buildings
For small chemical laboratories, electroplating workstations, and basements, select a high‑power, corrosion‑resistant model to extract and exhaust small amounts of corrosive vapors and exhaust gases.

Cross-flow air curtain machine
The cross‑flow air curtain employs a large‑diameter, slender cross‑flow impeller—also known as a tangential fan—directly driven by a single‑phase motor to generate a wide, planar, high‑velocity airflow. It is installed above or on the side of doorways. The unit features a flat, rectangular profile with a much reduced depth compared to centrifugal models, allowing it to seamlessly integrate into various ceiling designs. It is particularly well suited for spaces with limited headroom and where aesthetics and quiet operation are paramount, such as shopping malls, supermarkets, restaurants, office buildings, banks, hospitals, and residential garages.
Our company’s surface-type coolers are among the core heat-exchange devices in air-conditioning and ventilation systems. They are primarily used to cool and dehumidify air, and can also be switched to hot-water or steam mode during winter to provide air heating. By utilizing a refrigerant (such as chilled water, refrigerant, or brine) or a heat-transfer medium (such as hot water or steam) flowing inside the tubes, these units facilitate forced‑convection heat exchange with the air flowing outside the tubes, thereby regulating air temperature and humidity. As the central heat-exchange components of chiller units, fresh-air handling units, fan coil units, and other equipment, they offer high heat-exchange efficiency, flexible installation, and broad compatibility.
The ceiling‑mounted fresh air ventilator (ceiling‑type air handling unit) is a central air‑conditioning terminal unit that integrates fresh air exchange, air temperature and humidity control, air filtration and purification, and energy recovery. The unit features a concealed ceiling‑mount installation, suspended within the building’s suspended ceiling. It utilizes chilled water or hot water piping to provide cooling and heating, while simultaneously exhausting indoor stale air and supplying filtered outdoor fresh air. This system not only enhances indoor air quality in enclosed spaces but also regulates air temperature through heat‑exchanger coils, offering both ventilation and central air‑conditioning functions. It delivers energy savings, minimizes floor space occupation, and is widely suited for integration into fresh air systems in commercial, industrial, and large public buildings.
Our company’s Q‑type air heater is an industrial‑grade, forced‑convection heating unit that uses water or steam as the heat transfer medium. It is specifically designed for large‑space applications such as factory and mine workshops, warehouses, large buildings, and drying rooms. The equipment consists of a fan, an electric motor, and a steel finned‑tube radiator integrated into a single unit. Performance tests have demonstrated its stable and reliable operation. By combining “steam heat exchange with forced air supply,” it rapidly heats the air, delivering highly efficient heating and making it one of the mainstream solutions for heating high‑ceiling spaces.
