Not enough cylinder thrust affecting your production efficiency? Inconsistent force from stamping equipment leading to higher defect rates?
These are typical issues caused by insufficient local air pressure.
No need to replace the air compressor—simply install a pneumatic booster regulator at the point where higher pressure is required, and the problem is solved.
Pneumatic Booster System
1. What is a compressed air booster?
The VBA pneumatic booster is a highly efficient booster device that can double or quadruple the compressed air pressure without the need for an external power source.
Working Principle: The VBA boost valve utilizes a dual-piston structure and aerodynamic principles to achieve boosting. It divides the input gas source into two paths and enters the cylinder, pushing the piston and compressing the gas to form a high-pressure output.

Boosting principle of quadruple boosting type
2. VBA Series Pneumatic Booster Comparison
| Series | Port size | Pressure increase ratio | Max. flow rate (L/min（ANR）) | Set pressure （MPa） | Pressure adjustment mechanism | Installation |
| VBA10A | 1/4 | 2 times | 230 | 0.2-2.0 | Knob-operated with relief mechanism | Horizontal |
| VBA20A | 3/8 | 1000 | 0.2-1.0 | |||
| VBA40A | 1/2 | 1900 | 0.2-1.0 | |||
| VBA11A(VBA-X3239) | 1/4 | 4 times (Fixed) | 90 | 0.8-2.0 | Fixed type | Horizontal/Vertical |
3. VBA11A pneumatic booster regulator
VBA-X3239 model boosts air pressure up to 4 times.
Long service life: 50 million cycles or more.
Built-in silencer.
Magnetic reed switch can be mounted on top to count the number of actuations.
Fixed boost ratio eliminates regulator knob.
Mounting interchangeability with existing products (VBA series pneumatic booster).
Horizontal and vertical mounting available.
4. How to adjust the pneumatic booster?
| Models | Pressure adjustment method | Operating Instructions | Application Features | |
| Manual type | Knob-operated | 1. Manually rotate the regulating knob to set the pressure. 2. Turn the knob clockwise → Increase the output pressure. 3. Turn the knob counterclockwise → decrease the output pressure. 4. Tighten the lock nut after adjusting to the target pressure. | 1. Suitable for manual control by on-site personnel. 2. Intuitive operation, ideal for initial equipment installation or frequent on-site adjustments. | |
| Air-controlled type | Pilot air control | 1. An external pilot air pressure signal (pilot air) is input to the control port. 2. The pneumatic booster valve uses this pressure signal to adjust the output pressure. 3. The higher the pilot air pressure, the higher the output pressure (usually in a linear or proportional relationship). | 1. Suitable for remote or automatic control systems. 2. Often used with ITV electro-pneumatic regulator or solenoid valves to achieve remote pressure setting. 3. Improves system automation. | |
| Fixed type | Fixed multiplication ratio | 1. Factory-set multiplication ratio (e.g., 2x or 4x). 2. Dependent on input pressure, no adjustment mechanism. 3. If a different output pressure is required, the corresponding fixed model must be replaced. | 1. Suitable for applications where pressure settings are fixed and frequent adjustments are not required. 2. Prevents misoperation and improves system stability. | |
5. Notes on using VBA pneumatic booster
① If the pneumatic booster valve outlet pressure exceeds 1.0 MPa, confirm the pressure specifications of the connectors, air pipes, and air valves.
② A 2- to 4-fold boost pressure can be achieved; pay attention to the handle adjustment.
③ When installing a lubricator, it must be installed on the outlet side, and a filter device is also required on the outlet side.
④ The exhaust pipe must be routed separately to prevent back pressure.
⑤ When transporting, hold the unit by both ends; never by the center handle.
FAQ
1. How do I determine the required boost ratio?
This requires calculation based on the system's input pressure and the desired output pressure. VPC can provide professional technicians to perform accurate calculations.
2. What media can the VBA booster handle?
It can handle a variety of media, including air, nitrogen, hydraulic oil, and water. Specific compatibility should be confirmed based on the product specifications.
3. How to install air booster with tank?
For detailed installation instructions for the VBA pneumatic booster valve and VBAT air tank, please refer to this article: How to install booster regulator?
4. What is the difference between manual and air-operated models?
Manual models can only be set on-site, while air-operated models can be remotely operated using a separate pilot pressure reducing valve.
