G1A Series Single-Stage Single-Acting Air-Driven Gas Booster

CDI-G1A series are single-stage single-acting air-driven gas boosters powered by compressed air. Equipped with unbalanced air distribution valve for automatic reciprocating cycle. The pump body is constructed of aluminum alloy and stainless steel with 160mm drive piston and pump head exhaust cooling structure, fitted with imported high-performance seals. Recommended drive air pressure ≤8bar, max design drive pressure 10bar. Compatible with air, nitrogen, oxygen, CO₂, argon and other industrial gases. Used as inline booster unit for gas pressure boosting, constant pressure makeup and high-pressure leak test.

Core Advantage

Single-stage single-acting design with auto on/off function by built-in air control valve;
Robust aluminum & stainless steel construction with good corrosion resistance;
Imported sealing components for low leakage and long service life;
Full pneumatic design without electric motor, intrinsically safe for flammable gas working site;
Pump head exhaust cooling enables continuous long-hour operation;
Unified G1/2 drive port across full model range, easy for standalone or skid-mounted integration.

Application

Leakage & burst test for valves, pressure vessels, piping, heat exchangers and gas cylinders;
Constant pressure replenishment for gas storage tank & low-pressure air compressor upgrading;
High-pressure air supply for CNC clamping, pneumatic marking/inkjet equipment & CMM instruments;
Gas filling for autoclave, hydraulic accumulator, cable pressurization, safety valve calibration & new energy component pressure testing.
