Ruwac DAV deduster for plastic trimmings from high speed IWK tube filling machine IWK (Thailand) Ltd, Thailand 2017

Customer Name: IWK (Thailand) Limited

Customer Source: General Market Research

Customers Issue:

  • Plastic trimming pieces are evacuated much too slow from the collection chamber resulting in trimmings building lumps and clogging up the hose. This would stop the tube filler machine frequently for manual cleaning up of hose and collection chamber. Up to 10 % production time could be lost due the vacuum.
  • Before the Ruwac solution, another de-dusting solution was implemented in which the performance & connection diameters were not carefully calculated resulting in clogged tube trimmings within the hose connections. (low mbar of under 30 mbar which is EXTRACTION specification and NOT suitable for DEDUSTING)

Solution Offer:

  • The RUWAC DAV was tested and customized for this application. The RUWAC systems 280 mbar of vacuum and airspeed of over 40 m/sec gives no chance of clogging the hose anymore.
