P3300 series double-sided special gas control panel
P3300 series double-sided special gas control panel
Product details

Applied to the depressurization and gas supply of bilateral high-pressure gas cylinders, continuous gas supply can be achieved through manual switching on both sides, with blowing function.
The maximum input pressure can reach20.7 MPa (3000 psi)Corrosion resistance, clean room assembly testing, suitable for high-purity gas use in laboratories, gas analysis, etc.
