WestAir Gas Regulators Model 2123351-73-500

Manufacturer: WestAir Gases & Equipment
Model: 2123351-73-500
Type: Industrial gas cylinder pressure regulator
Function: Reduces high cylinder pressure to controlled, usable outlet pressure for industrial or laboratory applications.

WestAir regulators are designed to provide precise pressure control of compressed gases from cylinders, ensuring safe and consistent delivery to downstream equipment. 

Typical technical characteristics (212-series configuration)

While exact specs depend on gas type and CGA fitting, this model typically has the following features:

Mechanical design

• Single-stage pressure regulator

• Heavy-duty brass body construction

• Diaphragm-controlled pressure reduction

• Cylinder-mounted regulator configuration

• Manual pressure adjustment knob

Single-stage regulators reduce cylinder pressure to outlet pressure in one step and are commonly used for industrial applications and testing. 

Pressure ranges (typical configuration)

Based on model suffix “-500” and WestAir naming conventions:

• Maximum inlet pressure: up to ~3,000 PSIG (standard compressed gas cylinder pressure)

• Maximum outlet pressure: up to 500 PSIG (very high-pressure outlet version)

• Pressure regulation accuracy: approx. ±0.05 PSIG per 100 PSIG change (typical WestAir regulator spec)
