Ruck Etamaster inline tube fan with EC motor

The Ruck ETAMASTER inline tube fan (EM EC series) has an energy-efficient EC motor, this EC motor can be operated with a three-step control. 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 EC series is available with capacities ranging from 410 m3/h to a maximum of 5700 m3/h and with diameters ranging from 100 mm to a maximum of 400 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 energy-efficient Etamaster inline tube fans with an EC motor. 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.

Installation & maintenance How do you install an inline tube fan?

A musty bathroom, a kitchen full of cooking fumes or a room where the air just doesn’t seem to circulate properly: these are all situations where you long for fresh air. An inline tube fan is often the ideal solution, especially when air needs to travel over a longer distance or overcome greater resistance in the ventilation system. But how do you install, mount and connect an inline tube fan correctly? In this blog, we explain exactly what you need to know: from choosing the right position in the duct to ensuring a safe and future-proof connection.

Saving energy 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.
