Negative Pressure Unit D-range
4.1 Use according to appropriateness
The negative pressure unit of the D-Series serves for the filtration of asbestos
contaminated air, in temperature rage up +45 °C, with external exhaust for the air. During
asbestos sanitation works within closed rooms, you must avoid that asbestos fibres leave
the sanitation area and in this way endanger humans and the environment. For this
reasons, the sanitation areas (also called dirty area) have to be separated from the clean
area with the help of a negative pressure unit and kept in dynamic negative pressure.
An integrated filtering system establishes the conditions that the asbestos concentration
in the exhausted air does not exceed max. 1000F/m³. The exhausted air is blown in the
open air.
The device is not appropriate for the filtration of flammable gas or dust.
4.2 Description of the device
The negative pressure unit serves for the filtration of asbestos contaminated air via a 3-
steps filter unit. (D 60 and D 60 E only 2-steps). The inserted Hepa filter complies with
the requirements according to EN 1822 classification H13.
By stacking of several devices, minor floor space is needed.
 Smooth and easy-to-decontaminate housing
 Stable and light housing
 3-fold sealed hepa filter
 Hepa filter according to EN 1822 classification H13
 Very low emission during the change of the filter. Filter change in 3 minutes
 The filter change is indicated visually via a pressure gauge (for the D 60 E via a
signal lighting)
 Rustproof and powder coated housing
 continuously variable control 0 - 100% (SE and SRE)
 automatic soft starting, also after a power failure
 all operation and function elements are shock-protected
 stackable housing, ergo minor floor space
 Power optimised fan with high capacity
Options:
 Attachment housing for the second hepa filter (Double filtration)
 Attachment housing for pocket filter
 Acoustical indication for the filter change
 Suction adapter
