The SMC VBA40A-F04 is a high-performance booster regulator designed to increase factory air pressure locally. This unit can double the main airline pressure, providing a simple and energy-efficient solution for applications requiring higher force from actuators without the need for a separate high-pressure compressor. Operating solely on air, it requires no electrical wiring or power, making installation straightforward. The VBA40A series is known for its reliability and durability, making it an ideal choice for boosting pressure in clamping, braking, and other high-force pneumatic systems.
