The EBM Papst W4S250-CI02-01 model is an axial fan with a round wall plate, equipped with a voltage-controlled asynchronous external rotor motor. With a power of 69W, this fan can generate an air flow of up to 1100 m3/h, at a maximum back pressure of 80 Pa. It is designed to operate efficiently within a wide temperature range, from -25 to +50 °C. In addition, it is equipped with a built-in thermal contact motor protection to ensure a long service life. Thanks to its low noise level of only 54. 0 dB(A) and flexible mounting options, it is ideal for use in ventilation systems and heat recovery.
