To adjust a pneumatic door, you'll primarily be modifying the tension of the door closer which regulates its closing speed. Here's a breakdown of the process:
Adjusting Pneumatic Door Tension
The primary method for adjusting a pneumatic door is by manipulating the tension on its closer mechanism. This involves a simple adjustment screw.
Step-by-step Guide:
- Locate the adjustment screw: The adjustment screw is typically found on the door-end of the closer barrel. This is the cylindrical component that controls the door's closing action.
- Prepare your tool: You'll need a flathead screwdriver.
- Tighten the screw to slow the door: To raise tension and slow down the door's closing speed, turn the adjustment screw clockwise.
- Loosen the screw to speed up the door: To lower tension and increase the door's closing speed, turn the adjustment screw counter-clockwise.
- Test the operation: After each adjustment, open and allow the door to close. Observe the speed and adjust again as needed to get your desired speed.
Tips and Considerations:
- Incremental Adjustments: Make small adjustments at a time. A slight turn of the screw can significantly affect the door's closing speed.
- Test Frequently: After each adjustment, fully open and close the door a couple of times. This helps you accurately assess the impact of your change.
- Safety First: If you're uncomfortable making these adjustments, consider contacting a professional door installer.
| Adjustment | Direction of Screw Turn | Effect on Door Closing |
|---|---|---|
| Increase Tension | Clockwise | Slows down |
| Decrease Tension | Counter-clockwise | Speeds up |
Example:
If the door is closing too quickly, turn the adjustment screw clockwise slightly. Then, open and close the door to check the speed. Repeat as needed until you achieve the desired closing speed.
By following these steps, you can effectively adjust a pneumatic door's closing speed. Remember to proceed cautiously and test the operation after each adjustment.
