Air, Instrument Grade
Compressed air with low moisture and hydrocarbon levels
N2 / O2
Instrument Air is used as a clean source of oxygen for oxidation processes
Uses
- Source of oxygen for oxidation processes
- Oxidiser for flame ionisation detectors
- Combined with instrument acetylene in atomic absorption flame spectrometry
- Balance gas in calibration gas mixtures
Air, Instrument Grade — Stable Compressed Air for Measurement & Control
Coregas Air, Instrument Grade is supplied as compressed air in cylinders for plant instrumentation, control systems and analytical support. Specified for reliability in industrial environments, it’s delivered as a non-flammable gas under pressure and packaged for safe storage, handling and transport on NZ sites.
Typical Uses
Plant instrumentation & control: valve actuation, panel air, purge/blanket of enclosures per site SOPs.
Laboratory/industrial support: utility air adjacent to analytical equipment where a non-flammable compressed gas is required.
General industrial applications requiring clean, dry compressed air in packaged cylinders.
For applications with tight purity/moisture/hydrocarbon limits (e.g., specific detectors or calibration duties), consider Coregas specialty gas grades.
Why Choose Coregas for Instrument-Grade Air
NZ supply & support with local account management and rapid delivery.
Cylinder stewardship—return cylinders to Coregas for refilling or end-of-life processing.
Clear safety guidance for storage, handling and transport aligned to NZ requirements.
Safety & Handling Essentials (Summary)
Classification: Gas under pressure — Compressed gas; non-flammable.
General hazards: Cylinders may rupture/explode if heated; cool from a protected location in a fire.
Storage: Keep cylinders upright and restrained, out of direct sun, below 65 °C, dry and well-ventilated, away from traffic/exits.
Handling: Do not drag/drop/roll; use a suitable cylinder trolley. Prevent uncontrolled release.
PPE / Engineering: For normal handling, wear safety glasses, leather gloves, safety boots; ensure adequate ventilation.
Spills/leaks: Evacuate area, move leaking cylinder (if safe) to a well-ventilated remote area and allow to discharge; do not repair valves/safety devices; keep gas out of pits/basements.
First aid: Treat exposure to high concentrations as potential asphyxia; seek medical attention.
Transport & Classification (NZ / International)
UN 1002 – AIR, COMPRESSED
Class 2.2 — Non-flammable, non-toxic gas
Typical controls: secure cylinders during transport; keep valves closed and capped; ensure vehicle ventilation; driver informed of hazards and emergency actions.
FAQs — Air, Instrument Grade
-
Is instrument-grade air flammable?
No. It’s a non-flammable compressed gas, but cylinders are under pressure—protect from heat and physical damage.
-
What are the key storage rules on site?
Store upright, restrained, in a dry, ventilated area, out of sun/heat, away from traffic and building exits.
-
Any special PPE or ventilation needed?
For normal handling: safety glasses, leather gloves, safety boots and adequate ventilation.
-
How do we move cylinders?
Use a rated cylinder trolley. Don’t drag or roll; keep valve protection in place.
-
What do we do with empties or out-of-date cylinders?
Return cylinders to Coregas for refilling or end-of-life processing.
