4-73

4-73 columns of centrifugal fans

Purpose: Suitable for indoor ventilation and air exchange in factories and large buildings.

Direct impeller: 280-2000mm

Airflow range: 1000~220000m3/h

Pressure range: up to 3000Pa

Working temperature: -20 ℃~80 ℃

Drive mode: A, B, C, D

Key Features:

The fan adopts a single suction type with a backward centrifugal impeller, which has the characteristics of high efficiency and low noise.

Adopting an efficient streamlined snail shell design, it is more in line with aerodynamic principles.

The inlet of the casing is equipped with an efficient converging streamlined air inlet, allowing air to be evenly distributed within the width range of the flow channel.

※ Fans No. 2.8 to No. 6 adopt A-type transmission; Fans No. 8-12 are driven by C and D transmission, while fans No. 14-20 are driven by B, C, and D.

The transmission system consists of a main shaft, bearing housing, rolling bearings, pulleys, or couplings.

※ Fans can be equipped with corresponding accessories, such as import and export soft connections, damping spring composite shock absorbers, etc.

The fan can provide optional accessories such as air inlet adjustment damper, bearing temperature and vibration sensor, impeller cleaning nozzle, etc. for selection.

The explosion-proof fan is equipped with an explosion-proof motor and uses an explosion-proof impeller made of aluminum alloy material.
