2 % 100 conventional bend flow 150 bend Deflector Horizontal bend Vertical bend Comparison of pressure loss with the same volume flow 150 round set to 100% as reference value Due to the integrated guide vane technology, the vapour flows in the duct are stabilised and routed outside with the lowest pressure loss. Depending on length and construction of the waste air duct, the pressure loss in COMPAIR flow 150 is reduced by up to 79% compared with150-gauge round tube. On the one hand, this leads to improved exhaust air performance, and on the other hand, to substantially reduced noise generation in the kitchen. The contemporary COMPAIR flow 150 rectangular profile enables freedom of design in kitchen planning. without guide vane high speed uneven flow flow speed (m/s) with guide vanes low speed even flow The impressive performance figures of COMPAIR flow are based on engineering research and development. In close cooperation with the University of Applied Sciences in Osnabrück, especially the effect of the guide vane technology was examined using elaborate measuring processes, and optimised for flow.

With up to 70% less pressure drop, the proven Naber COMPAIR guide vane technology maximises hood performance and, at the same time minimises the noise of the extractor hood. The 90 bend with integrated sleeves on both sides enables rapid system assembly, even with direct connection of the hood. The small inner radius of the bends allows installation close to a corner/cupboard. The round tube provides a smooth transition to the other COMPAIR flow exhaust systems.

They provide optimum smoothing of the vapour flow in the deflector, horizontal and vertical bends. substantially less turbulence and impact surfaces reduced pressure loss ensures optimum volume flow COMPAIR flow 125 already clearly surpasses the exhaust air performance of 150-gauge round tube COMPAIR flow round 150 assures full performance capacity for hoods of the highest performance class, especially over short distances audible reduction of the noise level clear strain relief for the hood motor less wear and lower power consumption due to relief for the hood motor ideal for hoods with DC motors

With system construction heights of only 77 or 89 mm (outside height), COMPAIR flow meets all planning requirements. The sleeves with guide chamfers integrated on both sides of all bends and deflectors enable secure and quick system assembly of all tubes and moulded parts. MF/F-EST End piece

The guide vane technology in the bends and the low profile of the system allow for inconspicuous system installation and, at the same time, optimum flow performance of the extractor hood used. Powerful and quiet Modern kitchens increasingly open onto the living room. A powerful, quiet and highly efficient exhaust solution in an open kitchen area is therefore particularly important. The operation of the extractor hood should not cause any audibly disturbing noise and, at the The COMPAIR flow Star wall conduct systems meet the requirements for an air-tight building envelope in accordance with the energy conservation regulation EnEV09. When used in buildings with controlled domestic ventilation, the direct extraction of exhaust air (outgoing air) in the kitchen is recommended because, when using a recirculating hood, the replacement of kitchen vapours using the controlled ventilation system takes longer and the moist air condenses inside the building (mould stains and mildew). Ask your ventilation system manufacturer for more details.

The aim of flow bionics is metrologically optimised product design, for example, to minimise flow losses in air duct bend elements with rectangular crosssections (pressure losses through the formation of dead space, secondary flow and friction on the bend walls) by changing the curve geometry. Natural examples are provided by the ideal flow generated in the meander systems within the course of a river. flow separation no flow separation Flow speed and pressure loss in system comparison. With a great deal of innovation, using the latest simulation and measurement technology, the Naber development team consistently applied the idea all the way through to the series production of the COMPAIR bion deflectors. The focus was on the energy-efficient use of system components with extremely powerful hoods. high pressure loss low pressure loss All COMPAIR bion deflectors were optimised subject to the requirement of interchangeability, so that, taking the duct geometry into account, they can also be subsequently integrated into existing systems.

10 Quality of design The Naber range of conventional stainless steel wall conduct technology is in great demand, not only thanks its weather-resistant properties. The blinds and hoods, which are warp resistant and therefore have a long service life, are suitable for air duct installations of COMPAIR flow and round duct systems up to Ø 200 mm. An integrated backpressure shutter prevents ingress of wind and rain into the duct. Naber s customer service consultants will inform you about all system details.
