Description
High-performance liquid CO₂ regulator — 0–475 PSI, 45 CFM
A super-high-flow, dual-gauge CO₂ regulator built on the proven Series 3000 platform. Adjustable from 0 to 475 PSI and flowing up to 45 CFM, it delivers big volume from a liquid CO₂ tank — for airing up tires, on-board air and race cars, running air tools, industrial and inert gases, and HVAC/plumbing work, all 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.
Know exactly what it does
High volume, precise control
Super high flow
Up to 45 CFM — far beyond a typical portable compressor’s 4–5 CFM — so you air up big tires and run air tools fast.
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.
CGA320 brass connection
Standard CGA320 CO₂ tank connection in brass, with a soft seal washer included.
Built for high-pressure CO₂ jobs
Off-road, overlanding & race cars
Air up large truck, RV, and SUV tires and run air tools on the trail or at the track — no electricity required.
Air tools & purging
Drive impact tools, blow-off, and line purging from a CO₂ tank where a compressor isn’t practical.
Industrial & welding
High-flow delivery for industrial gas, plus MIG/TIG and inert-gas specialty tasks.
HVAC & plumbing
A dependable regulated source for HVAC condensate-line clearing and plumbing pipe purging.
Technical specs
Connect it & run it
Pair the regulator with the right tank connection and a properly-rated hose — and if you’re running compressed air instead of CO₂, there’s an air version too.
CGA320 nut, nipple & washer
The CGA320 regulator nut, 2″ nipple, and washer to connect the regulator to your CO₂ tank.
