This shoe looks very much like the shoe used in conjunction with floor springs. The energy used in opening the door is stored in a spring (compression, torsion, tension, volute or leaf), [25] and released to close the door. Spring tension is typically adjustable, altering both opening and closing force. Most door closers use oil-filled hydraulic dampers to limit closing speed, and allow for soft closing. Other types use a friction-based mechanical speed control mechanism. [26]

This type of door closer is referred to as a "tail" spring [32] and is one of the more simple mechanisms, having no damping control.Automatic Access are always able to find the perfect pneumatic door opener for the job in hand, and in particular find openers for more challenging environments and purposes.

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.
