Air quality standard exceeded

Coalescing filters are generally considered to be one of the most important items of purification equipment in a compressed air system, as they remove aerosols of water and oil, while eradicating solid particulates and micro-organisms.

This arguably makes selecting effective products particularly key and to back up its products, Parker has exceeded ISO8573-1:2010 air quality standards.

The company says: "The latest generation of OIL-X EVOLUTION compressed air filters from Parker domnick hunter offer unprecedented performance, which not only meets but exceeds ISO8573-1:2010 air quality standards, and has been validated independently by Lloyd's Register, the leading international approval authority."

The products use aerospace technology to optimise air flow paths and improve efficiency, enabling significantly reduced system operating costs to be achieved.

Coalescing filters are normally installed in pairs, in series, with one acting as a general purpose filter and the other as a high efficiency filter, to ensure a continuous supply of high quality compressed air with low operational costs and minimal maintenance.

The company continues: "It is important to remember, however, that filters do not remove all contaminants and that water vapour in particular must be removed using an appropriately specified compressed air dryer."

The Parker domnick hunter PNEUDRI MX heatless dryers are electronically controlled and compact systems, capable of providing 100% standby drying capacity at a fraction of the cost of larger, conventional systems, says the firm.

Most critically, these dryers deliver pressure dewpoints in accordance with ISO 8573-1:2010 class 1, 2 or 3 for water vapour and, when combined with the latest range of compressed air filters, can achieve Air Quality Classes 1.2.1 and 1.1.1.
