Vomat filtration systems, displayed and distributed by Oelheld, provide compact, energy-efficient solutions for the metal processing industry. The filtration systems are ideal for filtering oils and removing the ultra-fine particles that result from grinding, honing, lapping, eroding and other metalworking processes.

The automatically-controlled filter backwash process is activated on demand and separates contaminated oil from clean oil. Energy consumption is decreased through a combination of frequency-controlled filter pumps and on-demand filtration. High-performance, pre-coat filters ensure that clean oil meeting the purity class of NAS 7 (3-5 μm) is available for long periods of time. The filtration systems are low-maintenance, compact and range in available sizes from standalone units for single machines to plant-wide central systems. Their customizable modular concept has multiple cooling and disposal options and can handle mixed use of carbide and HSS.

Systems on display include the compact, standalone FA series, which ranges from 70 to 1,200 L/min flow rate, and the UBF vacuum belt filter. The belt filter has a filtration fineness ranging from 3 to 25 μm and is suited for filtering oils and emulsions contaminated with steel, HSS, binders and grinding wheel particles.
