5 Technical description
5.1 Intended use
Negative pressure unit with integrated 3 stage filtration unit to filtrate asbestos
contaminated room air.
The unit specially designed for the use in the contaminated area.
Over-pressure technology prevents the intrusion of contaminated ambient air into the
housing.
The negative pressure unit Compact 5.500 in ex-protection design may be utilized in
areas endangered by gas explosion Zone 2 according to EN 60079-10, whereas
additional national regulations have to be observed.
During asbestos sanitation works within closed rooms, you must avoid that asbestos fibres
leave the sanitation area and endanger human health and the environment. For these
reasons, the sanitation area (also called dirty area) has to be separated from the clean area
with the help of a negative pressure unit and kept under dynamic negative pressure.
An integrated filtering system establishes the conditions that the asbestos concentration in
the exhaust air does not exceed max. 1000F/m³. The exhaust air is blown into the open.
The segments used comply with the following standards:
•Motor Ignition protection type increased safety „e“ according to EN 60079-7
Asset group IIB
Temperature class T5
•Motor protection Ignition protection type flameproof enclosure „d“ according to EN 60079-1
device Asset group IIC
Temperature class T6
•CEE- Ignition protection type flameproof enclosure „d“ according to EN 60079-1
Connector Asset group IIC
Temperature class T6

5.4 Filter change
The frequency of the change of filter depends on the degree of pollution of the filter. If the
sealing up of the filter increases (contamination of the filter), the air capacity decreases.
For the control of the filter during the operation, the device is equipped with a manometer
(see image).
Important: Use only approved, faultless filter!
•In a new condition of the filter the manometer reads approx. 650 Pascal. (Analysed at
100 % capacity)
•We recommend a change of filter at approx. 1000 Pascal.
Optionally, the device can be equipped with an acoustic signal (horn), which indicated the
clogging of the filter.
