A gas spring, also known as a gas strut or gas lift, is a type of mechanical spring that uses compressed gas, typically nitrogen, to provide a force and support in various applications. It consists of a cylinder filled with compressed gas and a piston rod that extends and retracts within the cylinder.

The basic operation of a gas spring involves the movement of the piston rod against the force of the compressed gas. When the gas is compressed, it exerts pressure on the piston, creating a force that opposes the movement of the rod. This force can be used to support or counterbalance loads in different applications.

Gas springs are commonly used in a variety of industries and products. Some common examples include:

1. Automotive Applications: Gas springs are used in vehicles to support the weight of the hood, trunk, or tailgate, making it easier for users to open and close these components.

2. Furniture: Gas springs are often employed in office chairs, cabinets, and other furniture to provide adjustable height or controlled movement.

3. Aerospace: Gas springs can be found in aircraft seating, cargo doors, and other applications where controlled movement or force is required.

4. Medical Equipment: Gas springs are used in medical chairs, hospital beds, and other equipment to provide adjustable positions and support.

5. Industrial Machinery: Gas springs find applications in various industrial machines where controlled movement or force assistance is needed.

Gas springs offer advantages such as smooth and controlled motion, adjustable force, and reliability. They are chosen for applications where a constant force or controlled movement is required, and where mechanical springs may not be as suitable

The installation of a gas spring can vary depending on the specific application and the type of gas spring being used. Here is a general guide that can be adapted to different scenarios, but keep in mind that it's essential to follow the manufacturer's instructions for the specific gas spring you are installing. Also, be sure to take necessary safety precautions.

The pressure of a gas spring can range from five pounds to several hundred pounds. While most people can compress a lower pound pressure spring by hand. You  should never try to compress a gas spring to install it

NO.It is impossible to open the gas spring to replace the individual components without destroying it.

A gas spring can usually be operated around 50,000 times. That means the lifespan  depends on how many times it is opened and closed. A gas spring for a kitchen cupboard will usually remain functional for around 6 years .

Since refill gas springs require special equipment and training, we advise you not to try and recharge the gas spring.

A gas spring, also known as a gas strut or gas lift, is a mechanical device that uses compressed nitrogen to provide a controlled force for lifting, lowering, or counterbalancing a load. Here's a basic overview of how a gas spring works : Basic Components: 

● Cylinder: The main body of the gas spring, usually a cylindrical tube, contains the compressed nitrogen. 

● Piston: Inside the cylinder, there is a piston that separates the gas from the oil (if used). The piston is connected to a rod. 

● Rod: The rod extends from the piston and is attached to the load or object being moved.

Only nitrogen is used as the pressure medium inSWAN gas springs. About 75% of the air we breathe consists of this gas. Nitrogen is absolutely safe and harmless tohealth. In addition, nitrogen does not burn. On the contrary, nitrogen is used in the chemical industry to prevent and extinguish fires. In addition, every SWAN gas springs contains flame-retardant oil to lubricate the seals and to achieve certain functions, such as damping or rigid locking.
