The wall conduct connects inside with outside, in other words: the extractor system with the outside air. In times of energy-optimised construction, it ideally closes the opening of the building envelope when the system is not in use. The Flow Star GTS is the perfect solution for securely sealing the building envelope according to the Energy Saving Ordinance, also in energy efficiency houses. Blower door tested, the elegant, shapely stainless steel cover lies flush on the outer wall when closed. An all-round seal prevents heat loss and thus saves heating energy.

The Flow Star GTS is opened by the air pressure of the extractor system. Robust, low-maintenance springs and joints ensure purely mechanical, reliable and quiet opening and closing. An electrical connection is not necessary. Even in strong wind, nothing rattles. Guide vanes allow the air to flow to the outside with little pressure loss, an additional backpressure shutter is not necessary. This reduces the power consumption of the extractor connected and lowers the noise level.

Our wall conducts with stainless steel blinds in connection with the THERMOBOX are also perfectly suited for energy efficient houses and energy-saving measures. The models are available with diameters of 125 and 150 millimetres and, of course, with connections for round and flat ducts. Naturally, at Naber you’ll also find supply air ducts and supply air/exhaust air wall conducts in the version to suit your requirements. Because exhaust air needs supply air!
