2.2. Functionality of the system

The filter unit serves to suck off and filter polluted air (according to the intended use). First of all, the

coarse particles are separated at the prefilter mat in the filter section of the unit. The subsequent particle

filter cleans even fine smokes and dusts. The activated carbon filter absorbs gases and unpleasant

odours. An automatic filter monitoring indicates when a cleaning or a replacement of the filters is

necessary. The purified air is led back into the working room.

2.3. Intended use

The device is intended for commercial use. If the device is made publicly accessible, it must never be

operated unsupervised by authorized personnel, authorized by the operator.

The filter unit is intended for extraction and filtration of fumes that result from lasers or soldering jobs.

WARNING

Improper use can damage parts and be a danger to life and limb!

The device must not be used for the extraction of oil-laden welding fume, explosive dust

and gases, hybrid mixtures, glowing or burning substances, gases, water, etc. The

device must not be operated in explosive zones.

Dangers arising from fire.

If the sucked medium is combustible fume or dust, the operator must determine

beforehand which fire protection measures are to be taken.

2.4. Residual risk

CAUTION

Danger due to possible hazardous materials in the exhaust air flow.

Because the unit does not monitor the quality of the air in the exhaust air flow, we

recommend that you always guide the exhaust air flow exiting our unit to areas (e.g. to the

outside into the open air) in which there is no danger to any living being. To do this, it is

necessary to fit a suitable exhaust air line at the filter unit.

7. Maintenance

In accordance with national regulations, the operator is obliged to carry out repeat and functional tests.

Unless otherwise specified by national regulations, we recommend regular visual inspections and

functional tests of the device as described in the chapter “Maintenance intervals”.

You find the chapter “Maintenance intervals” at the end of the document. The general

maintenance (visual inspection, etc.) is also explained there.

In the chapter “Maintenance intervals” there is information on the maintenance intervals of the filter

elements. But these are only recommendations. Depending on the application (multi-shift operation,

dust generation, ...) it may be necessary for the operator to change the maintenance intervals.

In this chapter the maintenance work which is caused by wear caused during operation is described.

WARNING

Work on the open system entails the risk of electrical shock or accidental restart the

system. Both pose a danger to life and limb.

When cleaning and servicing equipment during the replacement of parts or when changing

to another function, set the device to maintenance condition first (see chapter “Reset to

maintenance state”).

A recommissioning of the device must only occur if it is ensured that the device is

functionally equivalent to the original state.

CAUTION

Hazards to the respiratory tracts are possible due to contact with contaminated filter

elements.

All maintenance work must only be carried out in well-ventilated rooms and while wearing an

appropriate respiratory mask! We recommend: respiratory protection half mask DIN EN

141/143 protection level P3. For all maintenance work ensure a cautious handling of filter

elements and components in order to avoid whirling up dust.

The operator is obliged to store and dispose of the collected dust in accordance with national or

regional regulations. For all maintenance or cleaning work please refer to the applying

environmental regulations. Pollutants and filter elements must be disposed of or stored according

to the regulations as well. If you have any doubts, we recommend contacting a disposal

contractor in your area.

7.2. Replacing the prefilter mat

The prefilter mat is installed upstream to the particle filter and separates the coarse particles. This

extends the service life of the particle filter.

The prefilter mat must be changed after a certain number of operating hours. The time depends on the

amount of accumulated dust, and therefore cannot be determined beforehand. At the latest, the prefilter

mat must be changed when changing the particle filter.

CAUTION

Whirling up dust is possible.

The prefilter mat is a disposable filter element. Do not try to clean the filter element.

● Open the service door of the particle filter housing (see chapter 2.1).

● Lower the lifting device (A) by turning the clamping screw (B). Therefore, use the hexagon key

that is located on the right of the clamping screw.

● Carefully pull the particle filter (see chapter 2.1) out of the housing.
