Mobile deduster is a term for mobile suction units of lower construction size. Firmly installed extraction systems see filtre plant.
Mobile dedusters typically have the following features:
- flexible location, low overall size
- residual dust content < 0,1% mg/m³ (see TRGS 553)
- low costs because of short pipe systems
- 100% heat recovery by direct refeed of the air
- prior for carpenters and joiner's workshops or in addition of central, used to capacity stationary suctions or for isolated solutions
- checked dedusters have the GS mark and the residual dust content is visual so that they guarantee the compliance with TRGS 553
- A-rated emission sound pressure level (measured without chips and dust load) ≤75 dB (A)
- equipment features: mostly mobile, 1 to 3 filling units, partially even with briquette press
- * Volumetic flow rate max. 8000 m³/h
- Connection diameter 300 mm
- Fan, filter and collection bins form a unit
- Wood chips collection volume max. 500 l
- known manufacturers: Schuko, SPÄNEX, Höcker Polytechnik, AL-KO, NESTRO
Classification of dedusters
according to EN16770:2018
Deduster type A
- ≤0,8 m³ area of aerosol-generated air
- Pressure shock resistance of the body is not specified
- Ignition protection and fire suppression system is not required
Deduster type B
- >0,8 ≤1,2 m³ area of aerosol-generated air
- Pressure shock resistance of the body ≥200 mbar
- Ignition protection is not required
- automatic fire suppression system is required
Deduster type C1 (offline flitre cleaning)
- >1,2 ≤2,3 m³ area of aerosol-generated air
- Pressure shock resistance of the body ≥200 mbar
- Ignition protection and fire suppression system is not required
Deduster type D
- >2,3 ≤3,5 m³ area of aerosol-generated air
- Pressure shock resistance of the body ≥200 mbar
- Ignition protection and fire suppression system is not required
