Duct leakage test in the US. A duct leakage tester is a diagnostic tool designed to measure the airtightness of forced air heating, ventilating and air-conditioning (HVAC) ductwork. A duct leakage tester consists of a calibrated fan for measuring an air flow rate and a pressure sensing device to measure the pressure created by the fan flow.
Pressure forces on a submerged body act perpendicular to the body's surface. The design of the Tainter gate results in every pressure force acting through the centre of the imaginary circle of which the gate is a section, so that all resulting pressure force acts through the pivot point of the gate, making construction and design easier.
A rambler gate in Gloucestershire. A rambler gate is a self-closing footpath barrier that is in common use in some parts of Britain. It is designed to allow pedestrians to pass but to provide an effective barrier to livestock. It resembles a squeeze stile but the gap can be expanded by pushing a pair of pivot posts apart. The pivot posts will ...

A blast gate is a gate valve used to focus a dust collection system's vacuum pressure for maximum dust (or other material) extraction at the desired location. Blast gates are positioned near individual pieces of machinery and operate by being closed by default, blocking air flow.
Interior of German mechanical fire damper inside of a galvanised steel duct. Fire dampers (or fire shutters) are passive fire protection products used in heating, ventilation, and air conditioning (HVAC) ducts to prevent and isolate the spread of fire inside the ductwork through fire-resistance rated walls and floors.

Manual gates are sometimes hung in the manner of a normal gate (i.e. hinged horizontally). In some places, bar gates are installed across suburban streets as a traffic calming measure, preventing through traffic, while allowing authorised vehicles such as emergency services and buses to take advantage of the shorter and more direct route.
