Your Trust Sit Stand Desk Partners

Mechanism Overview:
Pneumatic standing desks operate on the principle of gas-assisted springs, where compressed gas, typically nitrogen, flows through a sealed unit. This gas moves from one end of the piston to the other through valve openings, facilitating the extension and retraction of the desk.

Pressure Distribution:
The sealed unit ensures equal pressure on both sides of the piston. However, the pressure acts over a larger surface area behind the shaft compared to the front, as the center of the shaft occupies some surface area on the front side. Consequently, this design results in a greater force pushing the rod out during extensions.

Extension and Retraction:
Applying weight or force against the shaft causes it to move further inwards and retract. Compressed gas continues to flow through the valve openings, becoming increasingly compressed until the shaft fully retracts or the applied weight equals the force exerted by the gas-assisted spring. This compression occurs because the shaft occupies space previously filled by the gas.

Adjustability:
To accommodate changes in applied weight, users can manually adjust the tension settings of their pneumatic sit-stand desk using a wrench. This ensures optimal performance and responsiveness to varying workloads.

Gas-Assisted Springs:
The gas-assisted springs play a pivotal role in minimizing the manual effort required to adjust the desk’s height. These springs efficiently counterbalance the weight, making it easier for users to move the workstation to their desired height position.

Locking Mechanism:
Once users have selected their preferred height, pneumatic sit-stand desks typically feature a lever mechanism. This mechanism allows users to lock the gas-assisted springs into place, ensuring stability and security at the chosen height.
