Feature：

● Automatic switching between cylinders

● Preset output pressure

● Suitable for high purity gases: surface finish ≤ 20Ra(0.5μm)
● High quality valves with threaded fittings

● Buit-in 10 micron filter

● Each panel is pressurized with inert gas and tested for leaks with a helium leak detector

● High-pressure isolation valves provide secure and precise gas flow control for demanding applications.

● High-pressure purge facility enables efficient purging of high-pressure lines to prevent contamination.

● Process line isolation valve enables hassle-free maintenance or repairs without interrupting the entire system.

Purpose

Gas panel HPA1 Series is designed for delivery of non-corrosive non-toxic 
gases and gas mixtures of purity class up to 6.0 (99,9999%) in gas distribution 
systems with two gas cylinders,where slight pressure variation is acceptable.
The panel provides automatic switching between cylinders when one of them 
is becoming empty.

 General Information

Gas panel HPA1 Series contains two single-stage diaphragm pressure 
regulators and five diaphragm isolation valves mounted on a stainless steel base 
and connected by threaded 1/4” fittings*.
Applications:
• Chemical industry
• Microelectronics
