Compressed Air

Features

• Odourless, colourless and non-toxic
• Does not burn but supports combustion

Benefits

• When it is combined with a fuel gas, produces a flame with a lower temperature than an oxy-fuel flame
• The air-fuel flame is suitable for brazing and soldering applications with lower-temperature alloys
• Used in preference to oxygen because it gives a greater level of adjustment, allowing the thickness of the carbon coat to be varied

Applications and uses

• Brazing and hard soldering
• Can be used in alternative applications such as plasma-cutting
• Used in metallurgical processes such as die-casting and blast furnaces
• Compressed air cylinders are an alternative to a compressor
• Used to drive pneumatic drills
• Can be used in the carbon-coating processes. An air-acetylene flame is used to produce carbon which can be deposited onto the surface of a component to act as a release agent. Carbon-coating is used for aluminium extrusion and glass manufacture as a mould-release agent
