Guillotine dampers are a type of single-bladed obstruction that can completely cut off the flow of a piping or venting system, allowing operators to safely inspect or maintain them as needed. a damper is a valve or plate that stops or regulates the flow of air inside a duct, chimney, vav box, air handler, or other air-handling equipment. Low leakage slide gate isolation dampers are primarily used for isolation purposes where low levels of leakage and pressure drop are required. low leakage slide gate isolation dampers are available with chain drive and electric motor actuators. Self cleaning stainless steel blade seals are incorporated around the full inside perimeter of the damper frame. the atmospheric blade seal is furnished along the face and edges of the damper blade to minimize leakage into or from the atmosphere.
