PN-AD Duct air purifier is suitable for use inside the branch air duct of centralized air conditioning system. It caters to the needs of relatively large space, such as banquet halls, hospital corridors, centralized offices, and airport terminals. Installed inside air conditioning air duct, the product’s high sterilizing capability can ensure the cleanness of the air duct system, and thoroughly purifies air being delivered indoor through the air duct.

Featuring manual and automatic operating models, PN-AD can operate simultaneously with speed-adjustable fan system if optional automatic control sensor device is selected. Separated from air conditioning equipment power supply, PN-AD completely eliminated the compatibility problem with air conditioning control system. By combining multiple modules, the product is perfectly suitable for air duct with high wind speed . If air duct wind volume ≥6000m3/h, and wind speed ≥7m/s, PN-AD-I/10 model air purifier is recommended.
