Stable performance to suit all requirements

Stove jacket cooling, storage heaters, wood-burning stoves, underfloor convectors, tanning beds, air conditioners and heaters – common to all these applications is the need for a ventilation system of shallow design with high air flow rates. The ideal solution: Tangential blowers from ebm-papst.

The generally small impeller diameter (30 to 65 mm) to impeller length (up to 2×300 mm) ratio permits an extremely shallow, flat design. The large intake and outlet cross-section makes it possible to achieve a high air throughput rate with low flow velocities. Further characteristic features of tangential blowers are a long air throw and extremely low running noise.

Tangential blower

Crossflow blowers are available with an asymmetrical shaded-pole motor, a capacitor motor or a GreenTech EC motor with integrated commutation electronics (incl. tach output and PWM or analog input) to suit the application concerned. With the GreenTech EC motors it is possible to select a higher speed than for shaded-pole and capacitor motors, to overcome higher back pressures for example.
