SF Series Axial Flow Fans feature a smooth streamlined surface, offering advantages such as stable operation, high efficiency, low noise, and low energy consumption. The SF series fans are classified into three types by usage requirements: duct type, fixed type, and post type, and divided into 12 models by impeller diameter.
The HFJZ-A craftsman kitchen fan is a square-housed ultra-quiet multi-blade centrifugal fan specially designed for kitchen exhaust. It was engineered to meet the demand for low-noise kitchen fans in modern kitchens and the exhaust requirements of communal ductwork. Compared to conventional multi-blade fans, it offers advantages such as higher pressure and lower noise levels. Moreover, it features a high static pressure design to tackle long ductwork and high resistance typical of modern kitchen setups.
The T40 axial flow fan is suitable for ventilation and heat dissipation in general factories, warehouses, offices, and residences. Removing the casing allows it to be used as a free-standing fan, or it can be installed in spaced series along long exhaust ducts to increase air pressure in the pipeline. According to user needs, this series can adopt an external motor (mounted on the casing) with belt drive in its structure, designated as model KT40. It shares the same performance parameters as the T40 fan, with the primary function of exhausting high-temperature or moisture-resistant gases.
The HFJZ-B craftsman kitchen fan is a square-housed ultra-quiet multi-blade centrifugal fan specially designed for kitchen exhaust. It was engineered to meet the demand for low-noise kitchen fans in modern kitchens and the exhaust requirements of communal ductwork. Compared to conventional multi-blade fans, it offers advantages such as higher pressure and lower noise levels. Moreover, it features a high static pressure design to tackle long ductwork and high resistance typical of modern kitchen setups.
The DPT Ultra-Quiet Ventilator is a product developed by our company after introducing advanced technologies and manufacturing methods both at home and abroad.Suitable for ventilation in quiet places such as offices, hotels, villas, guesthouses, etc.
The FA series exhaust fan has the characteristics of sturdy structure, beautiful appearance, low noise, and low energy consumption, and is suitable for ventilation, air exchange, and cooling in general environments such as factories, warehouses, offices, canteens, and kitchens.
The CF4-82 series products all adopt Type A drive. This fan is equipped with a B35 motor, which is directly mounted on the side panel of the casing, eliminating the need for additional supports. Equipped with a 16-blade impeller for superior pressure performance, its compact housing is reinforced with angle iron on both sides. This design facilitates stable installation, presents a neat and aesthetic appearance, and allows flexible adjustment of the outlet orientation.

The air inlet and outlet can be connected to circular pipes of the same diameter, making installation simple and greatly saving pipeline design and installation costs. It has the advantages of large air volume, high pressure, low noise, low vibration, low power consumption, long service life, small size, light weight, and stable operation. This fan compensates for the insufficient static pressure of axial flow fans. It can effectively regulate air, removing moisture, dust, odors, and purifying the air to keep the indoor environment fresh.
The CBF Explosion-Proof Axial Fan is specialized ventilation equipment for hazardous environments. The fan is composed of an explosion-proof motor, blades, casing, etc. To prevent sparks from friction, the blades are made of cast aluminum alloy.The fan features low noise, low energy consumption, and superior performance. In addition to ventilation and exhaust, it can be installed in spaced series along long exhaust ducts to increase duct pressure. Unlike general fans in structure and material, its applications are similar.
The GDT high-pressure low-noise cabinet-type smoke exhaust fan is a high-pressure cabinet-type smoke exhaust fan specially developed and designed by the company for kitchen smoke exhaust in recent years, based on the multi-blade low-noise air cabinet and the rear-inclined high-pressure air cabinet, in response to market demands. It combines the pressure of high-pressure fans with the low noise of multi-blade fans.
The YWF Series External Rotor Fan is a new product developed by our company through repeated research and trial production. Compared with conventional axial flow fans, this fan features higher efficiency, lower noise, minimal vibration, compact structure, and aesthetically pleasing appearance. The impeller is directly mounted on the outer circumference of the external rotor, resulting in shorter axial dimensions. Its successful development represents a major breakthrough in the field of axial flow fans. This series has obtained multiple national patents.
The 4-72 Model Centrifugal Fan conveys air and other non-flammable, non-toxic gases that do not corrode steel. No viscous substances are permitted within the system. The dust and hard particulate content must not exceed 150 mg/m³, and the gas temperature must not exceed 80°C. This fan employs backward-curved blades with superior aerodynamic properties, delivering smooth operation, high airflow, minimal vibration, high efficiency, and extended service life. It is widely used for ventilation in industrial and mining enterprises, large-scale buildings, hotels, and restaurants.
The 9-26 Type High-pressure Centrifugal Ventilator can be widely used for conveying materials, air, and gases that are non-corrosive, non-self-igniting, and free of viscous substances. The temperature of the conveyed medium generally does not exceed 80°C, and the dust and hard particles content does not exceed 150mg/m³. It is suitable for high-pressure ventilation in general forging and smelting, glass, ceramics, radio, electroplating, storage battery industries, as well as material conveying in processing industries such as grain, feed, mineral powder, and plastics.
The FA series exhaust fan has the characteristics of sturdy structure, beautiful appearance, low noise, and low energy consumption, and is suitable for ventilation, air exchange, and cooling in general environments such as factories, warehouses, offices, canteens, and kitchens.
