General Aspects - HEYLO HL 400 Bedienungsanleitung

1. General aspects

ATTENTION: Always read before commissioning!
Please carefully follow the instructions in the operating manual. Non-observance will invalidate the
warranty. The manufacturer accepts no liability for any damage or consequential damage arising from
this.
The HL 400 is a mobile air filtration unit. The air is drawn in from the environment and passed through
a multi-stage filtration system. The filter stages consist of a pre-filter, two 2in1 combi-filters for gases
and particles as well as a plasma generator and a UV lamp.
The individual stages have the following functions:
Stage 1
Pre-filter
An aluminium filter is used as a pre-filter. The pre-filter filters coarse dust particles of more than 5
micrometres, such as house dust, dandruff, pollen. The filter can be washed out with water and can
therefore be used several times. HEYLO recommends replacing the pre-filter annually
2nd + 3rd stage
Charcoal filter:
The formaldehyde filter with activated carbon cleans the air of unwanted odours, gases and
substances. It also cleans the air of harmful formaldehyde. The substances are absorbed by the
activated carbon.
Variant 1: H14 filter according to EN1822
HEPA filters of class H14 are used, among other things, in medical areas such as intensive
care units and laboratories, in clean rooms and in other hygienic areas. The respective application is
decisive for the selection of the filter class.
The filters are EN-compliant and certified. H14 filters catch 99.995 % of all suspended particles from
a size of 0.1 µm, so that virus filtering is possible and e.g. coronaviruses are rendered harmless.
Variant 2: E11 filter according to EN1822
EPA filters of class E11 are used in living and working areas, among others. The respective
application is decisive for the selection of the filter class.
The filters are EN-compliant and certified. E11 filters capture 99.5 % of all suspended particles from a
size of 0.1 µm, thus enabling dust, bacteria and pollen filtration.
4th stage
Sterilising UVA light
UV sterilisation with 365 nanometre UV wavelength light can kill a variety of airborne bacteria. The
UV disinfection lamp is usually used for air, surface and water disinfection. It can purify the air,
eliminate musty odours as well as produce a limited amount of anions. This makes the air fresh and
avoids the spread of viruses in the air or on surfaces viruses. According to the World Health
Organization, the corona virus, bird flu virus, influenza virus and legionella bacteria are all larger than
20 nanometers.
5th stage
Ionisation
By applying strong electric fields, ionisers can electrically charge individual air particles and thus
increase the ion concentration in the room air. The charged particles are more reactive and can thus
destroy odour molecules and other pollutants. At the same time, differently charged particles attract
each other and form larger clumps that sink to the ground faster and are easier to filter out of the air.
