To limit the speed at which the door closes, most door closers use hydraulic (oil-filled) dampers, although spring mechanisms may also be used for damping.

Door closers which provide this two or three-stage action and close doors at a determined rate are called 'controlled' door closers.

Both stairways had doors that have wire mesh windows and are operated by hydraulic door closers.

Although these door closers seldom break, they need regular lubrication to keep operating smoothly and occasional adjustment to compensate for internal wear.

Pneumatic door closers, which feature a long, horizontal tube and are usually found on storm and screen doors, are adjusted by rotating the tube.
