Filter Units BT / BTC

Final filtration units for low dust emissions

Depending on the dust particle size distribution, emissions can be limited to 0,1mg/m3. Bag filters or cartridges are installed in chambers with modular configuration. Optimal selection of different filter material for each type of dust in collaboration with European filter manufacturers.

Automatic cleaning system with compressed air jet pulses. Certified compressed air tanks and blow tubes with jet nozzles mounted above the filter hoses, easily installed and removed with bulkhead connectors.

Electronic Controllers that feature constant monitoring and adjustment of the differential pressure with many regulating options. Reliable, economic and simple handling.

The dust is collected in hoppers and removed by rotary airlocks, screws, big bags or metal bins.

Measuring Components that Quarantee Air Quality & Filter Condition

  • Air pressure and air flow in the ductwork
  • ΔP inside the filter unit: constant measurement on the LCD screen
  • Air Quality: dust probe for real-time monitoring dust concentration on filter outlet (mg/m3)

Stationary Dedusting Units BΤΝ / BΤΡ

For the filtration & collection of particles extracted during industrial processes.

Designed according to each application’s specifications: type and quantity of dust, ductwork pressure drop and dust disposal system.
They contain: fan, filtering components, dust collection & disposal system.


Filtering Components: tubular filters, cartridge filters.
Operation: negative pressure.
Cleaning: with pressurized air, during operation.
Collection, disposal: bins, big bags, screw-conveyor / air-locker systems.


Filtering Components: tubular filters.
Operation: positive / negative pressure.
Cleaning: with mechanical vibration or low pressure reverse air, while the unit is “off”.
Collection, disposal: bins, big bags, screw-conveyor / air-locker systems.

Mobile Dedusting Units BS / BVS

They are a simple and economic solution for the retention and collection of various kinds of dry dust, for industries & workshops.

The high efficiency fan is connected via air-ducts to the machinery dust sources. Dust is retained and gathered in easily removable filtration & collection bags.

Filter type selections in conformity with dust type.


BS type, up to 6000 m3/h, an economic solution for direct air-intaking from machinery outlets, and efficient cleaning
of production surfaces.

BVS type, up to 7500 m3/h, possibility of closed galvanized
construction, mechanical vibration cleaning system,
and operation as a centralized dedusting unit with multiple intakes.


  • Small – medium quantities of dry dust.
  • Intake from 1 or more processing machines.
  • Wood and furniture factories, construction materials.
  • Plastics and resins production and processing.
  • Aluminum and paper processing.


  • Portable, possibility of wheeled mobile construction on request, and electrically connectable via CEE plug.
  • 100% re-circulation of air, zero heating energy losses.
  • Filter-bags can be cleaned many times before replaced.
