Mechanical accessories Accessories to optimally satisfy all building requirements. SHUTTERS. GRILLES. WALL AND ROOF DUCTS. FIRE SAFETY SYSTEMS AND SHUTTER ELEMENTS. Helios backdraught shutters, weather protection and ventilation grilles and roof and wall ducts are popular due to their pleasant shapes, practical handling and robustness. The current ventilation valves with their awardwinning design, innovative exhaust air elements for demand-based functionality, preliminary filter elements, poppet valves for supply and exhaust air operation and incoming air elements for the controlled supply of outdoor air. The Helios range has ideal solutions for any type of room and use. In order to prevent the spread of fire to adjacent floors and rooms in multistorey buildings, openings for ventilation ducts that cross fire sections are to be equipped with shut-off elements. Helios offers these for a wide range of installations and all required classifications. Noise-damping volume elements and volumetric flow stabilisers are simply pushed into the duct and are efficient solutions for reducing the sound level and to adjust or stabilise the air flow volume. The development of accessories optimally tailored to the corresponding fan ranges is part of Helios' corporate philosophy. EXHAUST, SUPPLY AND OUTDOOR AIR ELEMENTS. VALVES.
