Cyclones

Cyclones HE (single) and HE2 (twin) operate as pre separators of the final filtration system

Their geometry is optimized for high separation rates with great stability, for dust particles of diameter >10μm. The final filters will collect only the fine dust (diam. <10μm)

Cyclones are an effective solution:

  • When heavy loads and difficult types of dust have to be filtered
  • When the collected dust has to be separated according to particle size

Protecting the filters from coarse, moist, fibrous particles and highly concentrated dust.
Significantly reducing dust load and improving final filtration.
Resulting in an economical and more efficient solution.

Rotary airlocks

Rotary airlocks provide non-stop material discharge from dedusting & material transport systems. They are applicable to many industries, types of dust & granulate.

Operation:

  • They seal air leakage during material discharge ensuring high efficiency separation and continuous operation of cyclones and filtration systems.
  • They regulate and stabilize the material transport in pneumatic conveyance systems.

Construction:

  • Welded, St37 (optionally stainless steel)
  • Rotor seal & blades seal exchangeable (PU rubber/ for low wear)
Cyclones are centrifugal particle separators

The working principle is based on the apparent forces that draw the existing, inside the rotating air-stream, particles away from the center, onto the cyclone walls and finally into the collection cone.

Ideal for applications with large quantities of any type of dust and large diameter particles.

Mostly used as pre-filter units for the separation of thick, corrosive, moist dust, and the main filter-unit’s relief.
High efficiency cyclones HE can function as final separators, achieving collection ratios >90% for particles with diameters ≥ 10μm.
High efficiency ratios for thin dust can be achieved by
multi-cyclone units, an array of ≥ 2 smaller cyclones
in parallel configuration.
