Fans, dust extractors, blowers and side channel blowers

These products ensure dust-free surfaces, cool, warm or particle-free air, and can create vacuums or convey light bulk materials. Lenze frequency inverters provide the answer to the constantly increasing demand for process performance, modularization, system intelligence and energy efficiency.

Picking the right inverter depends on your operating conditions and customer preferences. Important influencing factors include the installation site (in the control cabinet or field mounted), the type of desired control and theenvironment, since commercial and industrial settings require different electromagnetic compatibility and leakage current requirements.

Typical applications

Material processing
Food technology
Plastics technology

Compact and robust

The fan is controlled e.g. with an i550 protec with an optional extension box with service/disconnect switch in IP54/66/NEMA 4X. Thanks to the switch, the fan can be cleaned and serviced easily and safely.
