In most cases, pneumatic doors are standard equipment on buses and rental cars.

Pneumatic clutch
The pneumatic clutch uses a small amount of air to accelerate the engagement and disengagement of the clutch disc, combining all the significant features of a disc clutch with all the advantages of direct air engagement. This type of clutch is used in the mechanical industry where the load driven by an electric motor needs to stop quickly and no longer slip.
Pneumatic door
In most cases, pneumatic doors are standard equipment on buses and rental cars. Pneumatic doors provide convenience for operators to open the large doors of such vehicles.
Pneumatic horn
Pneumatic horns come in various shapes and sizes and are used in industries such as ships, semi trailers, firefighting equipment, buses, and emergency vehicles.
Inflatable seats
Inflatable seats are made comfortable through a set of built-in airbag systems. The system includes an air pump, control electronics, pneumatic valve, and switch panel. The air pump inflates or deflates according to the user's needs. Air can be squeezed out by a person's weight to achieve passive deflation, or it can be actively deflated by the vacuum generated by a pump. Can be incorporated into the massage process.
Air suspension
Air suspension is now used in cars and SUVs (sport utility vehicles). Some high-end luxury cars and trucks come standard with air suspension systems. A compressor supplies air to the buffer device or rubber airbag located under the shaft or each wheel.
Brake assist device
The brake assist device helps reduce braking distance and enhance protection in emergency situations. The electronic control system monitors the brake speed, identifies "emergency stop", and initiates full braking within seconds, reducing the braking distance of the car by up to 20%. Nowadays, various vehicles are adopting this technology, including SUVs, trucks, and private cars.
fuel cell
A fuel cell is a device that converts chemical energy into electrical energy. Its principle is that hydrogen reacts with oxygen to produce water, which generates electricity and heat during the reaction process. Fuel cells provide DC (direct current) voltage and can be applied to electric motors, lamps, or various electrical equipment. There are multiple types of fuel cells, each using a different chemical composition.
Tire inflation
Tire inflation technology (central tire inflation) can be quickly adjusted according to changing conditions. Due to the central tire inflation improving traction, it can be used on poor quality transportation roads and steep slopes. It can reduce tire wear. Vehicles equipped with central tire inflation systems are less affected by wetland and road environments (such as potholes).
