Need of Compressed Air Quality

Compressed Air Quality is vital.

•••• Consequences if not

maintained

► Dramatically

increased maintenance costs

► Increased downtimes

PREMIER

ANSI/ISA-S7.0.01-1996The Instrument Society of America has published its Quality Standard

for Instrument Air (ANSI/ISA-S7.0.01-1996). The purpose of the

standard is to provide a definition for instrument-quality air.

The scope of the standard includes:

• Limits for moisture content

• Limits for entrained particle size and oil content

PREMIER

Summary of ANSI / ISA-S7.0.01• The pressure dewpoint measured at the dryer outlet should be maintained at least 10°C below the minimum temperature to which any part of the instrument air system is exposed.

• The pressure dew point should not exceed 4°C at line pressure.

• Maximum particle diameter of 40 micrometers is designated as generally acceptable. Pneumatic control devices that require instrument air with less than 40 micrometer particle sizes shall be equipped with additional filtration to meet the particle size limits for the device.

• Lubricant content in instrument-quality air should be as close to zero as possible, and under no circumstances exceed 1 part per million by weight or volume.

Dew point - Definition

It is the temperature at which the air

attains saturation (100% RH). In simple

words it is the temperature below which

condensation will occur, at the given pressure.

Compressed air drying, working on the principle of cooling and condensation, makes use of refrigeration systems. Pressure dew points of down to 3°C are achieved by these methods.

Compressed Air drying – By Cooling

PREMIER

Compressed air drying, achieved through a process called adsorption is called Desiccant Dryers. Adsorption

is a process of deposition of water vapour onto the internal

and external surface of the adsorption medium, without the

formation of a chemical compound. Pressure dew points of down to -70°C are achieved by these methods.
