Products Description

1.High-temperature axial flow fans are widely used in drying equipment for tobacco, wood, fruits and vegetables, and
medicinalmaterials.resistance to high temperature and high humidity, large air volume, high air pressure, low noise, high efficiency and energy
2.The fan features a novel structure, an attractive appearance, and superior performance. It boasts characteristics such as saving, and easy maintenance.
3.Due to factors such as different quantities (of fans), varying impeller diameters, adjustable blade installation angles, and different main shaft rotational speeds, the air volume, air pressure, and power consumption (of each fan) also differ.

The products in this series adopt a direct connection structure where the impeller is directly mounted on the motor shaft. Under allowable conditions, the circumferential speed of the impeller matches three rotational speeds: 2900 rpm (revolutions per minute), 1450 rpm, and 960 rpm.

This series of products is divided into 10 models based on impeller diameter, arranged in numerical order. The models correspond to impeller diameters of 10 units (specific unit to be confirmed, e.g., decimeters or inches) with required angles for sizes 3,3.5, 4, 5, 5.6, 6, 7, 8, 9, and 10.

Thickened stainless steel Frame

^{1、Thickened panels 304 stainless steel 2、structural robustness 3、corrosion resistance 4、without rust or deformation, delivering smoother power output 5、extending the fan's service life. 6、It represents a dual assurance of reliability and durability.}

High-power motor with pure copper windings

The fan is equipped with a high-power pure copper motor, which integrates high-purity copper windings and high-quality silicon steel sheets. This ensures efficient power conversion and robust power output, while also delivering low heat generation, stable operation, and a significantly extended lifespan.

Reinforced steel fan blades

Reinforced steel fan blades with high hardness that resist deformation and detachment. The impeller undergoes strict dynamic balancing calibration, offering excellent aerodynamics, high air volume, low noise, dust resistance, anti-rust and corrosion protection, ensuring smooth operation.
