1. Introductory Remarks The purpose of the present User’s Manual is to supply the Purchaser and the future User with directions within the range of application, installation, start-up and the operational use of the WPA-P-N portable radial fans. Therefore, installing, start up and operational use are exclusively admissible after getting acquainted with the contents of the User’s Manual.
2. Application WPA-P-N portable radial fans have been designed for air-supply ventilation or extraction ventilation of rooms and workplaces. They can be applied for general ventilation and for local exhausts. Additionally, WPA-P-N fans can be used or drying the humid rooms by forcing the multiple air exchanges.
