Zero Air

We are a prominent manufacturer, trader and exporter of Zero Air in India with more than 30 years of experience in this field. Zero Gas is extensively demanded in petrochemical, automobile and chemical industries. We provide Zero gas free from hydrocarbons to assure its safe functioning.

Zero Gas is a tasteless, odorless and non flammable gas. But it can help in burning process due to contents of oxygen available in high amount. Zero Air contains a lesser amount of hydrocarbons and vapor than atmospheric air.


Generally Zero Gas is produced by the mixing of pure Nitrogen and pure Oxygen under controlled atmosphere and composition. We at Hema gases supply continuous and high amount of zero air for some applications through cylinder Quad, where a number of cylinders are interconnected through a common outlet meeting the requirements of clients.

Sometimes Zero air is also referred as Dry Air or Synthetic Air because it’s man-made. Zero air is used in various electronic instruments such as Gas Chromatograph used in several laboratories and research centers. We provide good quality Zero air with negligible amount of impurities and we have in house laboratory equipments to check the impurities and purity levels of any gas.
