A less common type of dashpot is an eddy current damper, which uses a large magnet inside a tube constructed of a non-magnetic but conducting material (such as aluminium or copper). Like a common viscous damper, the eddy current damper produces a resistive force proportional to velocity. A common use of the eddy current damper is in balance scales.
Damper (flow) Opposed blade dampers in a mixing duct. 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. A damper may be used to cut off central air conditioning (heating or cooling) to an unused room, or to regulate it for room-by-room temperature ...
Inertia damper. An inertia damper is a device that counters vibration using the effects of inertia and other forces and motion. [1] The damper does not negate the forces but either absorbs or redirects them by other means. For example, a large and heavy suspended body may be used to absorb several short-duration large forces, and to reapply ...

There are two models of the common Banshees, the Banshee 110, and the Banshee 115. The Banshee 110 was originally only offered in 10/12. The 110 and 115 were later both available in a 9/12 port ratio, and 8 port for special orders only. After 1983, the Banshee 115 was made available in 8 port as standard. Both units could be fitted with coding ...
