The Elbaron electrostatic air cleaning equipment now available from M Buttkereit Ltd is a natural extension to their range of quality machine shop products.

Health and safety regulations covering air quality are becoming more rigorous, and the hazards of operating personnel ingesting airborne pollutants including oil mist and smoke particles in the 0.3-0.5 micron range have been well documented. The efficient at source elimination of industrial pollution, including oil, emulsions and smoke is the only answer, and the Elbaron range of air cleaning equipment provides the effective and economic solution.

With more than 30 models available, the equipment is designed to filter out particles greater than 0.01 micron in size, and is ideal for use on CNC lathes, machining centres, grinders, milling machines, drills and even quench/hardening systems.

A primary mechanical filter is used to separate out large droplets and particulate matter. The pre-filtered air then passes through an ionisation zone in high efficiency electrostatic filter cells. In this area, all particles either solid or liquid down to microscopic sizes, are electronically charged at high voltage. These particles are then deposited on collector plates which carry an opposite polarity charge. Separated liquid particles form a film on the collector plates which then flows back down into the host machine or collecting container. The air is then drawn through a final mechanical diffuser filter before discharge to the atmosphere.

The filters are selected to match the requirements of the installation including type of liquids, density of mist, air throughput volume and size of machine housing. For maximum efficiency, they can be fitted direct to a machine enclosure cabin above the machining area where direct air extraction can take place. If this is not practical, they can be mounted elsewhere on a machine or separate stand, with a hose connection for air and contamination removal. In a multiple machine installation, a single large filter can be employed as a group extraction point, with collection hoses fed to individual machines.
