Modular Mist Collector Uses Multi-Stage Filter

The Handte Oil Expert oil mist collector from Camfil Air Pollution Control is said to provide continuous operation, reduced maintenance and long service life using multi-stage filtration and a flexible, modular design. The collector is designed to meet challenging applications that use lubricant oils for machine cooling. Separation efficiency is as high as 99.97 percent on 0.3-micron and larger particles, with reliable handling of ultra-fine, hard-to-capture oil mist and fume particles.

A first-stage coarse mesh filter separates out large particles and chips, followed by two stages of the company’s CoaPack diffusion filters, consisting of a pre-filter and fine filter. Media separators in the CoaPacks allow optimum airflow through the filters while providing maximum usable media area. This design combines high-efficiency separation performance with self-cleaning capability via drainage of the separated lubricant. According to Camfil, benefits include reduced energy consumption, average filter life of 3 years and enhanced protection of the optional HEPA final filter, which may be used for removal of ultra-fine mists and/or clean air recirculation.

The compact, sturdy modular design is meant to optimize flexibility for installation. Four basic modules with different air flows may be combined in a large central system. Processes served include turning, drilling, milling, roughing, grinding, broaching, honing, rolling, deep-drawing and pressing. Units can be delivered ready for plug-and-play use without additional assembly required.

The operation of the Handte Oil Expert is practically maintenance-free, says the company. Filter changes require no tools. The closed filter cassettes eliminate worker exposure to the oil-soiled filter media and are lightweight compared to other, similar cartridges.
