【Material】The 4 inch backdraft damper is made out of a Galvanized steel, the flap leaves are made of aluminum, while the Axis and spring are made of stainless steel..
【Installation】The backdraft damper is installed by pushing it into the ventilation pipe as far as it will go. The position of the spring should be horizontal when the flap is installed horizontally so that it can be opened and closed optimally. This also applies to the vertical installation..
【Function】This airflow regulating backdraft shutter fits over the TD lip and is designed to improve ventilation by preventing air from re-circulating when the fans are not in use..
【Wide Application】 These backdraft dampers can be widely used in ACs, exhaust fans, extractors, range hoods, heating ducts, vents and other residential, commercial and industrial applications..
【Note】Back draught valves can be inserted into ventilation ducts which are flexible or non flexible. Cannot be used with plastic ducts as the sizes are different..

Temperature: Short Term 120℃/ Long Term 95℃.
Aluminum Foil General Purpose - Waterproof, Flame Retardant, Strong Self Adhesive, Directly stretched around the area to be protected, no adhesives needed..
The tape is in a black finish, Non-Reflective but absorbs light from ambient light sources. suit for blocking lighting, spills/leakages on heat-generating equipment (projectors, light cans, barn-doors, etc)..
This adhesive aluminum tape provides an excellent bond on metals, plastics, copper, ceramic, and concrete. Conformable and pressure-sensitive adhesive enables it to fit on corrugated joints and irregular corners..
designed to easily seal HVAC Air Ducts as well as other Hot or Cold Intakes..

...tate around the inner liner during a crash. It also eliminates contact with hard plastic or slip-planes against the skin..
PROGRESSIVE LAYERING — Giro helmets designed with Progressive Layering use dual-density EPS foam liners to address high- and low-speed impacts for more comprehensive energy management. 14 WIND TUNNEL VENTS — Giro helmets are engineered with our proprietary Wind Tunnel venting system. This elaborate design combines active vents in the helmet's shell with exhaust channels inside the helmet that thrust cool, fresh air over and around the rider's head while forcing heat and stale air out..
DEEP INTERNAL CHANNELING — The inner liner of the helmet is aggressively engineered to assist air flowing through the helmet, working in conjunction with our Wind Tunnel vents to provide an easy pathway for cool air to flow in and hot air to exhaust out. IONIC+ PADDING — Pure silver is the ingredient that gives IONIC+ padding the power to provider permanent, natural odor protection to keep your helmet feeling fresh..
