AC 2500 cfm backward curved centrifugal fan for ventilaiton system

1. An Overview of Centrifugal Fan

(1)Description

Backward curved centrifugal fans are used primarily for intake suction and do not require a scroll housing. They have high hydraulic efficiency. They usually offer a quiet and compact air moving solution. The Permanent Split Capacitor motors provide reduced operating costs and longer service life. Ball bearing construction allows multiple mounting options. Backward centrifugal fans have low profiles that do not need scroll housing. Air is discharged 360° radially from the impeller wheel. These units operate very efficiently at high pressures.

(2)Product Features

1. Material: Impeller: sheet aluminum

Rotor: coated in black

2. Bearings: Maintenance-free Ball Bearings

3. Direction of rotation: Clockwise rotation viewing rotor

4. Approval: All models have reached UL approval, CE approval and CCC approval

5. Motor protection: All models are fitted with an internal Thermal Overload Protection Device.

(3)Typical applications

Exhausting industrial processes, roof and building ventilation, cleanroom and other sensitive HEPA filtering application, laboratory and research facility ventilation, air conditioner, heat exchangers, in-line duct blowers, range hood, fire place inserts, humidifiers, dehumidifiers, hand dryer.
