1.4.1. Mobile Re-cleanable Filter Systems RHF hightec

Re-cleanable HEPA filter systems will be used for demanding requirements on the filter separation performance (HEPA), high particle concentrations and abrasive dusts.

Data

Dimensions 1 600 x 1 900 x 790 mm
Air flow 420 l/s [1 500 m3/h]
Admissible Operation pressure ± 6 000 Pa
Admissible design temperature 90°C
Compressed air cosumption per recleaning approx. 0.4 Nm3/filter element
Recleaning time per filter element approx. 6 s
Tightness of filter housing acc. to DIN 24 496 Lekage rate < 3 · 10-5 of nominal air flow at Δp = 2 000 Pa
Tightness of filter seat acc. to DIN 24 496 Lekage rate < 3 · 10-5 of nominal air flow at Δp = 2 000 Pa

Your benefits:

  • Optional possibility of recycling the purified dusts
  • Low disposal costs
  • No filter element exchange necessary

Examples of industrial uses:

  • Teardown of nuclear systems
  • Pharmaceutical production processes
  • Battery manufacture

More features:

  • Top-down principle
  • Lower depths of filter elements for critical dust
  • Very high cleaning pressure (up to 4 bar overpressure in nozzle bar)
  • Patented, reinforced RHF ? standard size elements
  • Pressure loss reduction through cleaning process, i. e.
    • Lower and more constant initial pressure drop after cleaning
    • Higher working pressure drop in filter possible
    • Formation of a filter “cake” on the surface of the filter medium
    • Good separation of agglomerated dust in the hopper
    • Suitable for different kinds of dust, especially for critical particles (rough, sticky, etc.)
