Product Details
Product Overview:
Our company manufactures fume purifiers—devices that use mechanical means to filter harmful gases and particulate matter from indoor air before discharging it outdoors, thereby meeting environmental standards. These purifiers are primarily used in hotels, restaurants, eateries, food-processing facilities, and urban environmental protection initiatives, helping to reduce pollutant emissions, improve air quality, and mitigate noise pollution.
Main pollutant components of cooking fumes:
Depending on the type, flue gas primarily contains aldehydes, hydrocarbons, nitrogen oxides, alcohols, and other hydrocarbon compounds.
Emission standards:
Oil-fume pollutants include organic exhaust gases such as benzene compounds, ethyl acetate, and total non-methane hydrocarbons. Emissions of organic exhaust gases shall comply with:
1. Class II Standard of GB 16279-1996 “Integrated Emission Standard for Air Pollutants”
2. GB 18483-2001 “Emission Standard for Cooking Fume in the Catering Industry”

Process Flow and Description of the Fume Treatment System:
Based on the site conditions and in compliance with energy-saving, low-consumption, and environmental protection requirements, and taking into account construction complexity and cost control, our company will integrate its existing exhaust ductwork with our oil-fume treatment system for processing. The treated exhaust gases will then be discharged through the ductwork.

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.
