The SMC VBA20A-03GN Booster Regulator is a high-performance air-operated pressure amplifier designed to increase pneumatic line pressure in industrial automation systems. Part of SMC’s VBA series, the unit uses compressed air as its power source and can boost outlet pressure up to approximately twice the inlet pressure without requiring electricity. The booster regulator helps increase actuator force, improve cylinder performance, and optimize pneumatic systems where higher pressure is required only at selected points in the circuit. The VBA20A model features a 3/8 inch port size, integrated pressure gauges, and silencer accessories under the GN configuration. Designed for industrial automation, assembly machinery, clamping systems, presses, material handling equipment, and pneumatic motion systems, it provides reliable pressure amplification while reducing the need for upgrading the entire compressed air network.
