What is pneumatic outswing door system?
Let me introduce our Pneumatic outswing door system.
Our product is widely used on coaches, tour buses, and intercity buses. It has a lift lock function that can lock the door automatically. We always customize the dimension for free to match different vehicles.
Safety is a top priority. Our system has functions like open and close anti-pinch, 5km/h power off, and inside and outside emergency release.
Our factory holds ISO9001 and TS16949 certificates and strictly controls the quality.
Here are some technical specifications. The control voltage is DC12V(24V). The rising height is 20mm. The pneumatic pressure is 0.4 - 0.8Mpa. The loading capacity is ≤2000N. The swing direction can be LH/RH. The ambient temperature range is -40℃—+60℃. And the max. swing angle is 140°.
The main components include door panels and door assembly parts like swing-arm, cylinder, and valve.
The operating principle is as follows. For auto operation, when the “open” or “close” switch is pushed, the solenoid valve actuates, driving the linear pneumatic cylinder to move up and down. Through the splined shaft, the linear motion transfers to rotation, causing the door to open or close. In case of emergency, rotating the emergency valve 90 degrees releases the air pressure for manual opening. And if a passenger or item is clamped during closing, the door will open automatically.
