The HTFC series multi wing low-noise cabinet centrifugal fan is a newly designed and developed product by our company to meet the needs of the increasingly developing commercial kitchen oil fume exhaust, industrial purification, and fresh air conditioning industries. Based on the digestion and absorption of advanced technologies at home and abroad, the principle of combining aerodynamics and aeroacoustics is applied. It has the characteristics of large air volume, high static pressure, low noise, and small vibration.
The box is made of high-quality steel plates bent into shape, with a beautiful appearance and distinct colors. It can be disassembled, transported and installed as a whole, making it easy to handle in some high-rise buildings.
The transmission wheel side bearing is installed on the outside of the box, which is easy to maintain, reduces the load on the main shaft, and extends the life of the main shaft and bearing.
Drive Options:
Type A: External motor for exhaust and general ventilation
Type B: Internal motor for fresh-air supply and general ventilation

Explanations:
1.The data of M1, M2, and M3 (with Type A motor placed at the bottom) in the table are for motors with maximum power. The dimensions of the universal models from 9# to 22# are as per the above table. For 25# to 30#, other motors with different powers are used, and the values may be adjusted accordingly.
2.The overall dimensions and inlet/outlet flanges shown in the table are conventional configurations. Data for other non-standard air outlet directions need to be provided separately.
3.The installation dimensions are for reference only and cannot be used for precise positioning.
The impeller of the transparent medium pressure fan is covered with a mechanical shell, and the center of the impeller is the air inlet. It has the advantages of light weight, beauty, high wind pressure, large air volume, and stable wind pressure. Widely used for ventilation or blowing on woodworking machinery, glass machinery, blown film machines, packaging machinery, plastic product machinery, and other industry equipment.
The XCF is a new type developed from the CF-11 series. Engineered to incorporate the needs of modern urban kitchens, this comprehensive fan balances features like high resistance, high static pressure, ultra-low noise, and safety in its design.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.Featuring a redesigned impeller with an optimized aerodynamic blade structure. This delivers key advantages: low noise, minimal vibration, and extended service life.
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 YE3 Series Three-Phase Induction Motor is a fully enclosed self fan squirrel cage three-phase induction motor, which adopts the national unified design standard. It has the characteristics of high efficiency and energy saving, high starting torque, low noise, small vibration, high reliability, power level and installation size in accordance with the IEC standards, and easy use and maintenance. This series of motors is widely used in general places and precision instruments without special requirements, especially suitable for industries such as reducers, air compressors, water pumps, oil pumps, assembly lines, packaging, food machinery, etc.
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 blades of the medium pressure fan are designed to have the advantages of large air volume, high pressure, low vibration and low noise.
The vortex air pump features a compact structure, small size, light weight, low noise, and both blowing and suction functions. The aluminum-alloy housing optimizes heat dissipation; the motor uses pure copper windings. Widely used in equipment support, water treatment aeration, aquaculture, gas conveyance, dust removal, bottle drying, material feeding, collection, etc.

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.
This silencer is compatible with both HFJZ-A and HFJZ-B models, further reducing operational noise on top of the low noise features of artisan fans. Ideal for high-end commercial kitchens requiring superior acoustic performance, including institutional cafeterias, hotels, and restaurants.
The medium pressure fan adopts stamped and aluminum alloy die-casting shell and fan blades, which are lightweight, novel in style, beautiful in appearance, and easy to install.The blades of the fan are designed to have the advantages of large air volume, high pressure, low vibration and low noise.
