Product Description

3.3" EC Motor,Sensorless constant airflow 20VAC 230VAC

 

Constant air volume is a type of heating, ventilating, and air-conditioning system. In a simple CAV system, the supply air flow rate is constant, but the supply air temperature is varied to meet the thermal loads of a space. Most CAV systems are small, and serve a single thermal zone.

 

Specifications:

Voltage 115VAC/60Hz
Shaft material 45#
Shaft runout ≤0.5mm
Performance QCF80-ES
Insulation resistance > DC 500V/1MΩ
Hi-pot AC1500V,50Hz,

 

Features:
Perfect drop-in replacement of 3.3” PSC motors
Controller embedded connecting to power source 120VAC/230VAC directly.
Built by UL standards and now under UL certification procedures.
Power range 20W~Max. 200W.
Efficiency over 80%, MORE energy saving.

 

Applications:
Central ventilation system/bathroom vent fans/air coolers/standing fans/wall bracket fans/air purifiers/humidifiers/industrial ventilation fans/air conditioners/automobile cooling fans
