Vomat systems for filtering oils and removing ultrafine particles that result from grinding, honing, lapping and eroding are available from oelheld U.S. Inc. The automatically controlled filter backwash process is activated only on demand and fully separates contaminated and clean oil.

Energy consumption is low with the combination of frequency-controlled filter pumps and on-demand filtration. High-performance precoat filters ensure that clean oil meets the purity class of NAS 7 (3µm to 5µm) for the grinding process for long periods of time.

The filtration systems are low-maintenance, compact and are available in several sizes, ranging from stand-alone units for single machines to plantwide central systems. Their modular concept, offering a plethora of cooling and disposal options, along with the ability to handle mixed use of carbide and HSS, allows for customized systems.
