ISTA Vertical Pressure Reduced Regulator (Face – UP) Green

This ISTA CO2 Regulator assembles without tools and uses an air-tight design for accurate, reliable CO2 output.

CHARACTERISTICS

Easy assembling, no tool required in fastening to CO2 cylinder.
With air tighten design, provides accurate and reliable CO2 output.

The ISTA Vertical Pressure Reduced Regulator (Face - UP) Green sets and holds CO2 output pressure from the cylinder to your diffuser — pair it with a bubble counter to fine-tune the injection rate; see our guide to CO2 & Bubble Count.

Specifications

Type: vertical pressure-reduced CO₂ regulator, face-up mounting

Needle valve: precision type, for accurate bubble rate

Finish: anodised, with laser-engraved logo

Fitting: hand air-tighten, no tool required

Compatibility

Fits face-up CO₂ cylinders — the valve on the top face — including the ISTA Aluminium CO₂ Cylinder (Face-Up). It sits vertically above the cylinder, so allow headroom in the cabinet.

Air-tighten design: it fastens to the cylinder by hand and needs no tool.

Safety & Precautions

Never fit or remove a regulator while the cylinder valve is open. Close the valve, bleed the remaining gas through the regulator until the gauge reads zero, and only then unscrew it.

Keep the cylinder upright and secured so it cannot be knocked over, out of direct sun, and below 50 °C. Hand-tighten only — never put a spanner on an ISTA controller.

Always run a check valve between the regulator and the tank. Without one, tank water can siphon back into the regulator when the gas shuts off.
