External Central Suction System for Oil Mist

(PresseBox) (Nordrach, ) An LTA customer manufactures sawing blades for various applications which are ground using oil. The oil mist produced during the process is sucked off and fed to an air cleaning system through pipes. As the previous air cleaning was insufficient a new system was purchased. The customer decided for a product by Messrs. LTA who delivered the perfectly adapted filter AC 20001 from the modular largemodule series introduced in 2008.

The AC 20001 is an electrostatic filter which is particularly well suited for this field of application. On the one hand, the electrostatic precipitation principle - which is unmatched also for filtering oil - helps to reliably keep within the required limit values.

On the other hand, the low pressure loss of the filter grants an energysaving operation.The oil precipitated in the filter is pumped back in the oil treatment system via a recirculating pump and retrieved.

A corresponding filter with energysaving EFF1 blower was externally installed to the pipe system adapted by a partner firm. The blower is controlled by a frequency converter as needed. In excess of this, operation over the weekend - when circulation and suction are clearly reduced - becomes possible by means of various switchpoints. This is another strong point of this energyoptimized system.

The scope of delivery of LTA for this project comprised the cleanable large AC 20001 type filter (effective suction output approx. 25,000m³) including attachment accessory and external operating panel, one delivery pump for evacuating the precipitated medium and the setting and commissioning of the complete system in January 2010.

The advantage of this system is the high separation degree of the electrostatic filter as well as the use of regenerative filter elements. Thanks to the use of regenerative filter elements, the filters may be cleaned as often as required which eliminates the high disposal and purchase costs for replacement filters.

LTA Lufttechnik is a renowned partner for complete solutions in air technology. The company projects, builds and delivers air filter and fire protection systems for trade and industry. For over 30 years, LTA has been researching, developing and manufacturing aerosol separation products. The electrostatic separation method is ecofriendly and has continuously been further developed and improved.
