The SMC VBA20A-03N Booster Regulator is a high‑performance pneumatic booster valve engineered to efficiently increase compressed air output pressure up to 2× the input pressure — all using only the system’s existing compressed air supply. Perfect for industrial automation, pneumatic tooling, pressurization systems, and energy‑saving applications where stable boosted pressure is required without additional power sources.
The specialty regulator series VBA is a booster regulator that saves money and energy by increasing the main line pressure up to two times. The booster regulator, when connected to air supply line, increases pressure up to two times and the main air supply pressure may be set low. Desired pressure increase can be easily adjusted.

Features
· Floating piston structure.
· Metal noise reduced by the implementation of a damper on the impact part of the switching valve.
· The high noise-reduction silencer reduces exhaust noise.
· Features a built-in mesh filter at the IN port, preventing operation failure due to contamination by foreign matter.
· The air-feeding tube is integrated with the main tube, mitigating condensation caused by cooling during exhaust expansion.
· Standard fittings can be used, enabling remote pressure monitoring, etc.
