the world leading supplier of air duct cleaning equipment

Danduct Clean supplies strong ventilators that can easily be moved from room to room - even stairs are no obstacle. Ventilator suction with build in HEPA filter



  • 2 models with airflow 4500 m3/h
  • Easy to clean and transport

With the new Danduct Clean VT4000 ventilator unit you have the perfect all-in-one solution to extract and filNegative air machinetrate all dust and debris from the heating, ventilation and air-conditioning systems.

The mobile unit is equipped with a standard 16-mІ Hepafilter, which allows you to use it even in strict surroundings like a hospital.
For easy cleaning and to minimise downtime the filter unit is equipped with a rotorclean system, which will also extend the lifetime of the filter significantly.
For extra filtration a Hepa filter cassette can be installed.

For easy transport it can easily be taken apart and put in the back of a truck. The VT4000 is a very powerful ventilator with airflow of 4.500 mі/h. For easy operation it has a control panel with vacuum meter, am meter and on/off switches.

VT4001 vacuum and filterunit with a build-in and replaceable EU6 filter and a Hepa filter cassette. Modular build-up and low weight

VT1500, VT3000 and VT10000

  • 3 models with airflow varying from 2000-10000 m3/h
  • 2 ventilators can be combined resulting in an airflow of up to 20000 m3/h
  • Easy to move
  • Can be connectet to a 16 m2 HEPA filter

Choosing the right size of ventilator is a paramount issue in creating a sufficient negative airflow in the ducts. Test have been showing that 10 meter pr. second / 33 feet pr. second will transport the dust and most other particles to the filter.

The range of ventilators provides airflow from 2.000 - 10.000 m3/h and by connecting two ventilators together they can move as much as 20.000 m3/h.

The ventilators can be connected to a filter unit with 16 m2 HEPA filter. The HEPA filter is classified between H13 and H14 with a filtration of 99,97% of all particles down to 0,3 micron. The HEPA filter is mostly used in hospitals or other sensitive areas.
