Zero Air

Coregas zero air is compressed air packaged in cylinders for analytical instruments, laboratories and industrial applications where a clean, non-flammable air source with minimal hydrocarbons is required. It’s supplied as a gas under pressure with clear guidance for New Zealand storage, handling and transport. (See Safety & Transport below.)

Typical Uses

• Instrument air for analysis & monitoring: feed air for detectors, dilution/purge streams and zeroing sequences where hydrocarbons must be minimised.
  

• Laboratory & industrial utilities: clean, dry air adjacent to analytical equipment and process control.
  

• General industrial applications requiring non-flammable compressed air in a cylinder package.
  
  

If your method demands specified moisture or THC limits (ppmv/ppb), confirm the required grade at ordering.

Why Choose Coregas NZ

• Local NZ supply & support with fast delivery and technical guidance.
  

• Cylinder stewardship—return cylinders for refilling or end-of-life processing.
  

• Clear NZ transport guidance (UN, Hazchem, class) for site SOPs and contractor inductions.
  
  

Safety & Handling Essentials

• Classification (GHS): Gas under pressure — Compressed gas; Signal word: WARNING; H280: Contains gas under pressure; may explode if heated. Non-flammable.
  

• General hazards: cylinders can rupture/explode in fire; cool from a protected location.
  

• Storage (P410 + P403): Protect from sunlight. Store in a well-ventilated place. Keep cylinders upright, restrained, below 65 °C, dry, and away from traffic/exits in a non-combustible area.
  

• Handling: do not drag/drop/roll; use a proper cylinder trolley. Avoid uncontrolled releases; ensure adequate ventilation.
  

• PPE (normal handling): safety glasses, leather gloves, safety boots; respiratory protection not required in normal use.
  

• Spills/leaks: evacuate, move (if safe) to a ventilated remote area and allow to discharge; do not repair valves/safety devices; keep gas out of pits/basements.
  

• First aid: adverse effects not expected in normal use; treat high-concentration exposure as potential asphyxia risk.
