The Labmart GHA304 Hydrogen Air Generator is a 2-in-1 laboratory gas generator designed to provide both high-purity hydrogen and dry, oil-free compressed air from a single system. It delivers up to 300 mL/min hydrogen and 2000 mL/min air, with specified hydrogen purity of 99.999%.

The GHA304 features LED display, automatic operation, over-pressure protection, two-stage over-voltage protection and voltage stabilization, drainage switching and dust filtration for multi-stage purification. It provides 0.3 MPa hydrogen pressure and 0.4 MPa air pressure. GHA304

3. Detailed Product Description

Product Overview

The GHA304 Hydrogen Air Generator combines hydrogen generation and air generation in a single laboratory instrument. The catalogue identifies it specifically as a Hydrogen Air Generator (2 in 1) and describes it as a multi-purpose instrument. GHA304

The system provides two separate gas outputs:

• Hydrogen: maximum flow of 300 mL/min, with specified purity of 99.999% and output pressure of 0.3 MPa.
• Air: maximum flow of 2000 mL/min, with dry, oil-free air quality and output pressure of 0.4 MPa. GHA304

The GHA304 is designed for automated operation, with gas production initiated by switching on the unit. The catalogue also highlights low vibration, low noise and stable output pressure and flow rate. GHA304
