PROPER USE AND TYPICAL FEATURES
The fans are only intended for the transfer of air or air-like mixtures. They cannot be used in hazardous areas for the transfer of gas, mix vapours or
mixtures. Also cannot be used for transfer of solid components in transfer medium.
R14 axial fans with integrated external rotor ELECTRONICALLY COMMUTATED motor are not ready-to-use products, but designed as components for
air-conditioning, air supply and air extraction. The fans may only be operated when they are installed as intended & instructed, and when safety is
ensured by safety equipment according to EN 13857 or by other protection measures.
Axial fan is intended to be mounted on an air-conditioning, heat pump or evaporator heat exchanger housing with four screws so that the housing of application prevents
access to rotating parts from the rotor side and the protection grill prevents access to rotating parts from the front side. The heat exchanger's housing prevents also
access of water to axial fan from the rotor side.
This appliance is not intended to be built as a partition fan (mounting in outside windows or walls) unless it is built into an end-application which is
designed for that purpose.
The fan is intended to be permanently connected to fixed wiring.
The fan is intended to be connected to electrical power supply system with earthed neutral e.g. of type TN, TT.
The fans are only to be operated within the ranges specified on the motor name-plate.
Cycling operating mode: only with cycling via control signal (OFF=0V / ON=10V).
The manufacturer of the end application is responsible for keeping to the Electromagnetic compatibility (EMC) guideline 2014/30/EC.
The fan is designed for operating in 'pollution degree III' environment - applications acc. to EN 61800-5-1:2008.
Typical features
Variable Speed - setting via linear voltage input (0-10V) or PWM signal or other common ways.
High efficiency throughout the entire speed range.
Low-noise operation across the entire speed range.
Integrated EMC filter.
Sensor power supply 10VDC, max. 10mA.
Maintenance free ball-bearings and dynamically balanced rotating parts.
Control circuit is SELV isolated from main power supply (including an external power supply for sensors).
