Product Details
Product Overview:
Window‑style ventilation fan (square window exhaust fan), specially designed for installation in glass windows and square wall openings. It is an axial‑flow, direct‑exhaust ventilation device featuring an integrated ABS flame‑retardant plastic structure with a circular front air guide and a square outer frame. When powered on, the fan blades rotate to expel stale, polluted air. A built‑in spring‑loaded, self‑opening windproof louver ensures that the louvers automatically open for ventilation when the fan is running and close automatically when it stops, effectively preventing mosquitoes, rainwater, and drafts from entering. The unit is equipped with a fully enclosed, moisture‑proof motor, offering quiet operation, energy efficiency, and easy installation—simply fit it into a pre‑drilled hole in the window glass or a pre‑cut square opening in the wall. Ideal for kitchens, bathrooms, small apartments, and retail spaces where basic ventilation is needed, it quickly removes humidity, odors, cooking fumes, and stuffy air.
Core Advantages of the Products:
Dual-purpose window installation: Compatible with glass window openings and pre-embedded square holes in walls; no complex ductwork required, ensuring quick and easy installation.
Automatic windproof closure: The unit features a built-in louvered enclosed air outlet that provides protection against rain, dust, and insects, eliminating the need for an external rain cover.
Moisture-resistant and durable: The all-plastic body is waterproof and rust‑proof, making it resistant to aging even in the high‑humidity environments of bathrooms and kitchens.
Low-noise and energy-saving: Ball-bearing motor, low power consumption, smooth operation, and energy-efficient for everyday ventilation.

Stainless steel frame model (custom-made): Ideal for kitchens with heavy grease and油烟 and coastal environments with high salt spray, offering excellent rust resistance and corrosion protection.
Applicable use cases:
1. Home renovation residential setting
Dehumidify and eliminate odors in bathrooms and showers; provide simple fume extraction in small‑apartment kitchens; ventilate and prevent dampness in storage rooms and walk-in closets; and facilitate air exchange and heat dissipation through bay windows and balcony windows.
2. Commercial Storefront Scenarios
Window installations for convenience stores, nail salons, barbershops, and small bubble tea shops help vent indoor heat and unpleasant odors; they also assist small food‑service establishments in exhausting kitchen fumes.
3. Small Storage / Agricultural Shed
Install windows in rural utility rooms and small poultry houses to provide ventilation, reduce humidity, and dissipate ammonia odors; ensure moisture control and air exchange in small storage facilities.
4. Small-scale tooling scenarios
Ventilate windows in rental units, temporary construction-site dormitories, and makeshift offices; provide ventilation and dehumidification for small basement compartments.

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.
