Description
High-performance air regulator — 0–475 PSI from a 3000 PSI tank
A super-high-flow, dual-gauge regulator built on the proven Series 3000 platform. It drops high-pressure air (up to 3000 PSI) down to an adjustable 0–475 PSI and flows up to 45 CFM — enough to air up tires and run air tools off-grid from a scuba/SCUBA-style air cylinder, with no electricity required.
⚠ Working-pressure warning. Although the regulator adjusts from 0–475 PSI, every accessory connected to the outlet must be rated for your working pressure — up to 475 PSI maximum. Using components not designed for the pressure can cause failure and personal injury. Remember that gas expands as temperature rises. Confirm the ratings of all downstream hoses, fittings, and tools before use.
Running CO₂ instead of air? This is the high-pressure air version, with a Scuba (& Yoke) tank connection. For a liquid CO₂ tank (CGA320), see the liquid CO₂ regulator (242-1011).
Know exactly what it does
High volume, precise control
Super high flow
Up to 45 CFM — many times the 4–5 CFM of a typical portable compressor — so it airs up big tires and runs air tools fast, with no electricity needed.
Wide adjustment
Dial in anywhere from 0 to 475 PSI to match your tool, tank, and downstream setup.
Dual chrome gauges
Monitor tank and outlet pressure at a glance with chrome-cased dual gauges.
Non-freezing & self-venting
Designed to run without freezing under normal conditions, with self-venting for safer operation.
Light aluminum body
A lightweight aluminum body with a durable black anodized finish — easy to carry and mount.
Scuba/SCBA connection
A 3000 PSI Scuba & Yoke tank connection fits common 3000 PSI Scuba high-pressure air cylinders.
Portable high-pressure air, anywhere
Off-road & overlanding
Air up large truck, RV, and SUV tires and run air tools on the trail — no compressor, no power.
Air tools & purging
Drive impact tools, blow-off, and line purging from a high-pressure air cylinder.
Race cars & pit
Fast, compact, high-flow air for the track where a shop compressor isn't available.
Industrial & HVAC/plumbing
High-flow regulated air for industrial gas, HVAC, and plumbing tasks.
Build your portable air source
Pair the regulator with a high-pressure air cylinder and mounting gear for a complete on-board or portable air system.
