We recommend the AeroFlex in situations where it is very important that the air is steered. The adjustable fins steer the air in the desired direction. This enables perfect steering of the air in broad animal houses, animal houses with obstacles, or in poultry houses with aviary or cage systems. The AeroFlex with a V-type slide valve guarantees the desired throw even at minimum ventilation levels. The air is then bundled to create a ‘jet stream’. To ensure a long service life, the AeroFlex is made entirely of plastic and stainless steel; it can also be custom-made to fit any opening. The AeroFlex valves are also available in transparent (daylight) and multiple designs. The AeroFlex is self-opening and is closed by a motor. The fins are installed in front of the slide; the fin position has little or no impact on the effective air intake.
