Instrument Air Packages

Instrument Air Packages

An Instrument Air Package consists of all the necessary equipment – air compressors, air receiver, air dryer and air filtration – to enable the supply of instrument quality air to a facility. Instrument quality air must be free of contaminants and water vapour, and should conform to the international ISO standard for compressed air quality.

A completely self-sufficient instrument air package can be packaged within an enclosure and shipped to the site for simplified installation and commissioning. Even the smallest of air compressor packages can be provided as a complete, pre-engineered and turn-key system.

Components of the Typical Package:

Air Compressors

Facilities are dependent upon instrument air to maintain their operation. Accordingly, most Instrument Air Packages include two compressors – one operating – the other a redundant standby.

Air Receiver

An Air Receiver stores compressed air to provide additional capacity when required.

Air Dryer

An Air Dryer removes water vapour from the compressed air to ensure that no water will condense from the air when used. The typical pressure dewpoint range is -40 to -100 degrees C.

Air Filtration

Filters are required to remove oil vapour and particulates from the air stream.

Heated Enclosure

The completed air compressor package is usually installed in a self-framed, heated enclosure

Northwest can fabricate instrument air packages from 2hp to 500hp. We can accommodate any area classification or specifications and build to your needs.Any custom configuration is available. Please contact for more information
