The decentralised ventilation unit is quick and easy to install, so the day-to-day use of a room does not need to be interrupted or disturbed for long. After just a few hours’ access to the room, the unit is installed and ready for operation.
The start-up of the ventilation system is a task which Airmaster is happy to help with. Start-up can be with or without functional performance testing.
Changing the filters on Airmaster ventilation units is necessary to maintain the units in the best possible condition. Very dirty filters will result in pressure loss, forcing the unit to work harder to provide the desired airflow – this is not energy efficient. Failure to maintain the filters may also affect the quality of the indoor climate.
This depends on multiple factors. For several years, Airmaster has been systematically collecting filters from many different types of units, room types and locations to learn more about this. Based on our findings, we recommend the average filter change intervals below.
The intervals may vary if the unit is installed in particularly polluted areas, such as construction sites or in rooms with a lot of dust.
This means that units installed in typical offices, classrooms and institutions should have their filter changed at least every 14 months.
Airmasters guidelines regarding service interval should be considered as a supplement to any national requirements.
To ensure low operating and servicing costs on an Airmaster ventilation unit, Airmaster uses, as standard, filters with an exceptionally large surface area in relation to the airflow for which the units are designed.
Compared with recognised brands of central ventilation systems, the filter surface in relation to the airflow in the filter of an Airmaster ventilation unit is roughly 2.5 times larger.
Not only does the filter have a long service life, but its large filter area results in lower energy consumption as the energy needed to draw air through the filter decreases the less resistance there is in the filter.
A lower final pressure also contributes to lower energy consumption throughout the life of the filter.
Airmaster supplies particulate filters which comply with the new filter standard, EN ISO 16890. The new EN ISO 16890 test method takes into account the filter’s ability to remove a range of particle sizes, which the previous standard (DS / EN 779: 2012) did not.
The ISO 16890 classifications mentioned are the filter classes we use most. Other filter classes can be supplied on request.
Airmaster also supplies a wide range of filters for earlier models of Airmaster units, allowing us to continue to change filters regardless of the age and model of the unit.
Filters in Airmaster ventilation units are placed in a frame which forms a tight seal between the two. Unfortunately, we often find that when unoriginal filters are used, they do not fit tightly in the filter frames and thus do not comply with EN 1886:2007. The use of unoriginal filters can therefore cause excessive leakage, resulting in more soiled components, higher energy consumption and poorer air quality.
Airmaster therefore always recommends the use of original Airmaster filters.
