Door closers are widely used in both residential and non-residential settings. At home, they are most commonly found on screen and storm doors. They are also used in numerous applications in commercial, industrial, institutional, and public facilities from libraries and schools to museums and airports. Pneumatic door openers convert energy (typically air) into mechanical motion and are used in a similar way to automatic door actuators. They combine at least one door operator with a control unit and an air compressor.

When installing a fire door closer , it is important to follow the correct steps and refer to the manufacturer’s instructions. If you need advice on which fire-rated door closer is right for you or any fire door closers product, please do get in touch. Vallancey, Charles (1812). Account of the Ancient Stone Amphitheatre Lately Discovered in the County of Kerry: With Fragments of Irish History Relating Thereto. Graisberry and Campbell. p.33. What sets pneumatic door openers apart from other automatic door openers is that they use air pressure instead of electronics to produce the energy to move a door. This has a number of highly useful applications which means that Automatic Access can provide solutions for pretty much any context where an automatic door is required. When door closers are mounted in the header they are known as transom closers. [33] These can be HO (hold open) or NHO (none hold open).

Q&A

Pneumatic openers are extremely versatile and can be used for both interior and exterior automatic doors. They are ideal for multi-door applications because the cost per door leaf decreases significantly as the number of door leaves increase. A single control box may power up to two pairs of doors simultaneously and this flexibility results in significant savings in material and installation costs. Michael Panish.

Spring hinge uses a spring mounted in a hinge and is integral to its design. The spring can be either visible or hidden within a tube and can be found more commonly on interior doors. When used on doors that open both ways they are known as double action spring hinges. In buildings that require noise control (Studios) door closers play an important part in the suppression of unwanted noise both in and out rooms and the buildings themselves. A self-closing hinge combines door closers and spring hinges with an optional hold open feature into one component. These closer hinges eliminate the visual and physical clutter of using additional devices, as well as reduce maintenance problems associated with overhead and in-floor door closers. They are especially useful where other types of closers are difficult to use. The most durable self-closing hinge can handle doors up to 440 lb.This article needs additional citations for verification. Please help improve this article by adding citations to reliable sources.

Firstly, they can be used in buildings where the need for a low energy design is important. This is because with pneumatic doors openers, safety sensors are not always required. Since the pneumatic automatic operators are powered by pressurized air, they are quiet, efficient, and very reliable. Finally, because pneumatic openers use air instead of electronics, they can be employed in hazardous situations. Unlike electrical actuators there is no high-voltage wiring at the door frame, and the control box, which contains the electrical timing circuits, can be remotely located outside the hazardous area.

Some of the key features of fire door closers include adjustable latching and closing speed . This gives you the ability to adjust the door closer to specific fire code requirements, ensuring that the door closes at the correct rate to provide maximum protection.Lloyd, G. E. R. (1973). Greek science after Aristotle. New York: Norton. ISBN 0393043711. OCLC 514642. https://www.britishnewspaperarchive.co.uk/viewer/bl/0002135/19741126/039/0003– via British Newspaper Archive. {{ cite news}}: Missing or empty |title= ( help) Controlled closers” use adjustable hydraulic valves to variously regulate the door’s opening and closing speed, latch speed, and delayed action return. These allow setting of the “sweep speed” (the rate which the door travels along the majority of its closure, the sole closing setting on basic closers); the “latch speed” (the rate in the last 10 to 15 degrees of closing arc, allowing it to be set faster than the "sweep" to ensure proper latch closure); “delayed action” (which slows sweep speed dramatically for roughly the first half of its range, allowing more time for passage), [27] and opening speed (preventing a door from being opened too fast, a useful feature in crowded environments, and those where the young, old, or infirm may be present). It is also particularly well-suited to exterior doors where there is a danger of wind catching and blowing them open, potentially harming the door, nearby objects, people, or pets.
