Product Details
Product Overview:
The company’s duct‑type micro‑electrostatic purifier (also known as a duct‑mounted electronic air purifier) is a modular air‑cleaning device specifically designed for central air‑conditioning and fresh‑air systems. It uses a high‑voltage electrostatic field to ionize and capture particulate matter in the airflow, effectively removing PM2.5, dust, pollen, bacteria, and other pollutants. Additionally, it can be equipped with photocatalytic or UV modules to provide odor elimination and disinfection functions.
The device features a low‑drag design, requires no consumable replacements (the dust‑collection module is washable and reusable), and is easy to install without taking up additional space. It is widely used in ventilation systems across commercial, public, and industrial settings, effectively improving indoor air quality and extending the maintenance intervals of HVAC equipment.

Classification description of Product installation types:
Return-air vent installation: Installed in the return air grilles of fan coil units, air handling units, and ductwork of packaged air conditioners, with a thickness of only 6.8 cm, it requires no additional floor space for installation.
Duct-type installation: Installed in the supply or return air ducts of air-conditioning or fresh-air systems, it is suitable for systems with large airflow rates.
Air-conditioning unit-type installation: Installed within the casing of an air-handling unit (AHU) or a packaged air handling unit (PAU), it can be assembled in a modular fashion.
Independent ducted/mobile: Suitable for purification retrofitting of standalone ductwork or for independent spaces without central air conditioning. It should be noted that micro‑electrostatic purifiers are primarily designed for use with fan coil units (FCUs), air handling units (AHUs), and similar systems; they are not self‑contained, fan‑equipped purification devices. Therefore, if a central air‑conditioning system is unavailable, one should opt for a mobile or wall‑mounted air disinfection unit that includes its own built‑in fan.
Key points for Product selection recommendations:
Clearly define the application scenario: It must be determined whether the micro‑electrostatic purifier is installed at the return air grille of a fan coil unit, in an air duct, within the housing of an air‑handling unit, or used as a mobile device; equipment configured in different installation modes exhibits significant variations in external dimensions, airflow rate, and connection interfaces.
Determine the purified air volume (ventilation rate): Select based on the total supply airflow of the fan coil units or air handling units, typically following a 1:1 matching ratio—meaning the purification equipment’s airflow capacity should be equal to or greater than the air conditioning system’s actual supply airflow. For return-air‑type systems, it is recommended to provide a dedicated unit for each fan coil; for ducted systems, calculate the total airflow of the main ductwork and allow for a 10%–15% margin.
Assessment requirements for purification efficiency: Medical facilities, laboratories, and other settings have stringent microbial disinfection requirements and should use Products with a sterilization rate of ≥99.9%; for ordinary commercial buildings, a PM2.5 purification efficiency of ≥90% is sufficient to meet the needs.
Consider the equipment installation space: Micro-electrostatic purifiers typically range in thickness from 7 to 61 cm. The return-air grille–type Products feature an extremely compact design (with a thickness of only 6.8 cm), leaving very limited space at the front of the fan coil unit; while duct-type and unit-type Models require预留 installation sections based on their external dimensions.
Cleaning Cycle and Maintenance Costs: Unlike conventional HEPA filters, the micro‑electrostatic core boasts the advantages of being consumable‑free and washable. In mildly polluted environments, it only needs to be cleaned every 6 to 12 months; in moderately polluted settings, cleaning is required every 3 to 6 months. However, please note that the honeycomb microporous structure may develop a water film during washing, resulting in a longer drying time (2 to 4 hours of air‑drying). Users should plan maintenance intervals accordingly.
Security Configuration: Prioritize models equipped with safety interlock switches and fan‑on‑demand functionality to ensure seamless integration with the air-conditioning system, automatic power shutdown upon door opening, and enhanced safety for maintenance personnel.
Custom Feature Extension: If the space has specific requirements—such as high formaldehyde concentrations, severe TVOC levels, or the need for intensive deodorization—we recommend adding optional modules, including an activated carbon filter, a HEPA filter, or a UV sterilization lamp.

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.
