Ruck® Etamaster inline tube fan

The Ruck® ETAMASTER inline tube fan (EM M series) can be operated with an on/off switch or variable speed control, depending on the model. The Etamaster inline tube fan from Ruck® can be mounted directly on a tube, but we recommend the corresponding Ruck® fast clamp to reduce vibrations and noise through the duct.

The Etamaster has a built-in thermal switch to prevent burn out. In addition, the inline tube fan is equipped with a Mixed-Flow impeller with stator, as a result of which the fan will still produce a low sound level at a high flow rate. The EM M series is available with capacities ranging from 124 m3/h to a maximum of 3180 m3/h and with diameters ranging from 100 mm to a maximum of 315 mm respectively.

Ruck ventilatoren GmbH, is a leading German company with more than 25 years of experience. They are market leaders in the field of inline tube fans. With more than 300 enthusiastic employees, they work together on new developments and techniques on a daily basis. The company ensures quality assurance in order to deliver a great product with the latest ERP (Energy Related Product) requirements.

Tips to reduce your energy bills with good ventilation
Tips to reduce your energy bills with good ventilation
Energy prices are skyrocketing, and decesion have to be made between eating or heating. It is time to make our homes more sustainable and thus save energy. In summer, our homes use less energy than in winter. In summer you are outside more often and the heating does not have to be switched on. In winter, we often keep the windows closed to keep the heat in, but unfortunately that is when the problems arise. There is no fresh air coming into our well insulated houses. The lack of fresh air leads to high CO2 levels, which in turn leads to various health complaints.
