Product Overview: Self-Contained Air Suspension for Vehicles Without Onboard Air Supply
The YSR914-99 is a specialized air suspension seat engineered for drivers who want the superior comfort of air suspension but whose vehicles lack an onboard air source. This Manual Truck Air Seat offers greater elasticity and stability than mechanical suspension seats, making it a popular choice among drivers seeking enhanced ride quality. Featuring a built‑in 12V or 24V electric air compressor, it converts electrical power into pneumatic energy, eliminating the dependency on vehicle air systems. The two‑point or three‑point seat belt configuration ensures safety while adhering to ergonomic principles, with a working air pressure range of 0.8–1.2 MPa-solving the problem of insufficient or absent onboard air supply. For trucks, buses, marine vessels, and construction vehicles without an air source, this seat is the ideal solution for upgrading to air suspension comfort.

Technical Deep Dive: How the Electric Pump Air Suspension Works
The air suspension damping seat inflates the airbag through the intake pipe using onboard power (air source pressure typically 0.7–0.9 MPa). When inflated, the airbag supports the seat's own weight plus an operator mass of 40–130 kg, along with the additional forces generated by vehicle vibration during travel. The seat base's exhaust induction switch (fan switch) senses body weight and interacts with the airbag control valve to regulate air pressure (intake and exhaust). Working air pressure typically ranges from 0.3–0.7 MPa. The driver can fine‑tune the seat to the most comfortable air pressure position-the damping balance point-achieving excellent smoothness. Suspension travel remains between 10–70 mm, and the hydraulic damping cylinder works in concert with the suspension to deliver effective shock absorption, vibration isolation, and anti‑seismic characteristics.
While air suspension seats offer superior comfort and better shock absorption on rough roads compared to mechanical suspension seats, they traditionally require an onboard air source. This has limited their use in trucks, trains, mining vehicles, yachts, and other equipment lacking air systems, or where the air supply is insufficient during operation.
The YSR914-99 Solves This Limitation: By integrating a 24V power supply and electric pump, this seat can function on any vehicle with electrical power-regardless of whether an air source is present. This innovation has made it one of the most popular choices for air suspension upgrades across diverse vehicle categories.
