SPÄNEX to launch innovations at LIGNA.IN

Published on :Monday, September 6, 2021

Dust extraction and filter plants manufacturer for wood processing industry, SPÄNEX will launch a new innovation for the industry at the upcoming LIGNA.Innovation Network (LIGNA.IN) that is scheduled between September 27 and 29.

The background to this new development are customer requirements where, due to local conditions, the filter systems cannot be installed outside the building as required by the European standard DIN EN 12779. The tried-and-tested alternative solution of arranging the filter system indoors and equipping it with flameless pressure relief devices is often impracticable for structural reasons, so a new solution concept was developed.

The special feature of this system concept are the compact dust extractors, which are installed as a battery. They are complete separation stations with extraction fans on the clean air side, which achieve particularly high efficiencies. Energy saving motors of efficiency class IE 3 (optionally IE 4) are used as standard, their speed is controlled via frequency converters to adapt the extraction capacity to the respective demand, so that highly efficient systems are created.

The individual dust extractors are disposed of via mechanical or pneumatic conveyors and the separated chips and dust are either conveyed into containers or silos. The intelligent control technology ensures regulated and safe operation of the extraction systems. Optionally, the control system can also be equipped with a remote maintenance module so that the functionality of the systems can be checked by the SPÄNEX service department at the customer’s request.

Up to now several plants with maximum extraction volume flows between 10,000 and 40,000 m³/h have been put into practice on the basis of this new plant engineering concept.

The special adaptability of the units has shown that this concept represents the optimum technical solution for many applications and ideally complements the extensive product range of SPÄNEX for the implementation of individual extraction units tailored to the needs of the customer.

For the LIGNA trade fair, it was planned to set up and operate two extraction centres on the stand, each with two dust extractors, whereby each dust extractor would have provided a maximum air volume of 10,000 m³/h. This means that the total dusty air suction capacity for both stations would have been a maximum of 40,000 m³/h. This would have extracted the woodworking machines exhibited and demonstrated by the Weinig Group.
