Rectangular Square Cabinet Centrifugal Duct Exhaust Fan
Ventilation and smoke exhaust equipment at the end of air-conditioning， Centrifugal duct fan with large air volume Square duct fan
- The impeller of the EHD centrifugal duct fan is a forward-inclined multi-blade centrifugal impeller with single-sided suction. The fan is designed to enter and exit horizontally.The square air inlet and outlet can be directly connected with the air duct. The fan motor is a special motor for air conditioners. The whole machine has low noise, stable operation and long service life.Long life and other characteristics.
- Fans are divided into 16 specifications according to the diameter of 140~500mm.The series air volume is 130~5500m3/h, the total pressure is 45~470Pa,
- In order to meet the requirements of noise in different places, it is divided into:Ordinary type: all of its materials are galvanized steel sheets formed by biting; Muffler type: The fan part is made of galvanized steel sheet formed by snapping,The box board is a color-coated board with noise-absorbing material inside, and the frameIt is made of aluminum alloy profile, and the air inlet and outlet are equipped with filters.
Fans can be widely used in air-conditioning projects such as office buildings,
hotels, museums, gymnasiums, culture, education and health.
Working temperature: -20~+40℃ (Can be continuous operation)
Humidity: less than 90%
Medium conditions: air (dust content does not exceed 100mg/m3)
Power supply: three-phase, 380V/50Hz
Single-phase 220V/50Hz (some models)
- The fan impeller and casing are all high-quality galvanized steel plates, and all molds are produced and formed by biting. The impeller undergoes static and dynamic balance correction,The balance accuracy is not greater than G5.6.
- The silencing type air box panel is folded and formed by a CNC bending machine, and is formed by connecting self-tapping bolts and aluminum alloy profiles.
