This is a mobile or fixed position deduster with particular high performance for extracting from one or several dust sources. Fitted with a vibration cleaning system for the filter elements for low filter resistance. It offers a high degree of operational safety and optimum comfort. It has been tested by the German Wood Trade Association and certified.

We would like to give additional relevant information to current European and German regulations focusing on the following points:

  1. The European relevant regulation covering all centralised dust extraction systems is prEN 12779, which will become effective this year (pr = proposal)
    This regulation refers to extraction plants above air flow of 6000 m³/h and will cover all new plants
    Exceptions are going to be made for mobile dedusters with air flows below 6000 m³/h, that have to meet special requirements if installed indoor and mainly focus on explosion and fire prevention measures.
  2. The existing occupational exposure limit should not exceed – according to regulations – 2 mg/m³ using standard machinery. Exceptions are being made for certain special machines.
  3. Regarding sanders, there is no recommendation for separate extraction as sophisticated extraction plants are equipped with certain safety devices to cover additional risks.
  4. According to regulations, minimum air velocity at outlets is 20m/s, which does not cover higher requirements of machine manufacturers that should be met in any case and means for average calculation reasons basically higher air velocities.
  5. Sophisticated extraction plants respectively mobile dedusters are required to meet residual dust content in the outlet air of 0.1-0.2 mg/m³, which allows operation of such systems – especially mobile dedusters – with 100% return air all the time.

 

Taking all requirements into account we recommend the installation of mobile dedusters of certain sizes providing the following main advantages:

  • In line with European and German regulation requirements (all certifications available)
  • Indoor installation allowed providing 100% return air with residual dust content in outlet air max. 0.2 mg/m³, in case of outdoor installation return air can be provided by ducting equipped with – if required – fire gates
  • Mobile dedusters type EA250/300 equipped with additional required safety devices (possible also for EA200 if requested)
  • Automatic fire extinguishing system
  • Certain explosion tested equipment
  • Operational noise level without additional silencer equipment 75 respectively 80dB(A), with silencer equipment 67 respectively 71dB(A)
  • Discharge to be effected by filling tanks, rotary valve or briquette press (additional accessories)
  • Dedusting can be effected by compressed air jet-dedusting system instead of vibration system to cover increased requirements (additional accessories)
  • Fully automatic operation of the extraction system that can be equipped with automatic slide valves.
