They combine at least one door operator with a control unit and an air compressor. Essentially, pneumatic door openers utilize the power of air under pressure to automatically open a door. The pneumatic system is built around a standard closer so the door will operate manually at all times, opening automatically on activation of a switch, access control system, etc. 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.
The systems are easy to operate and can be installed in libraries, laboratories, and churches. They are also used in areas where hazardous materials are being handled. These doors are intrinsically safe. The compressed air system does not need high voltage or hydraulic fluid to operate and the control panel for the doors can be located up to feet away, which means fewer chances of being exposed to materials that may be hazardous.
