> Application > The Filtration Mechanism

 

 


While air cleaners are most commonly associated with the removal of tobacco smoke in pubs and restaurants, the added ability of the Aircare 2000 Series to remove odours & eradicate bacteria has meant that they are suitable for a range of other environments.

GP Surgeries & Waiting Rooms
The ability to eradicate airborne bacteria is proving increasingly important in environments where the risk of the spread of infection is particularly high. GP surgeries & waiting rooms are prime examples where the use of air cleaners incorporating anti-microbial filters can help reduce the spread of infection.

Veterinary Practices
The incorporation of carbon filters provides the ability to minimise animal odours, while the pre- and secondary filters work to remove pet dander (small dust particulates arising from animals) & create a more pleasant environment - at least for the humans.

Dental Practices
The fine particulates that can arise during the course of dentistry have made the Aircare 2000 series a valuable means of preventing the concentration of these substances & potential dangers should they become embedded in the lung.

Ozone Control
Ozone may be necessary to protect us from global warming, but when at ground level it can cause respiratory problems. The flexibility of the Aircare 2000 Series means that different filters can be used to control specific & known contaminants, such as the ozone generated by photo-copiers.

Odour Control
The flexibility in the filter system means that a range of odour problems can be addressed, particularly when they arise in confined spaces or a localised area within a large space. To this end, Aircare 2000 Series units have been deployed to assist staff involved in handling certain types of foodstuffs whose odours are particularly strong.

The filtration system in the Aircare 2000 Series has the ability to deal with all of these because it is based on a multi-stage filtration process. The overall design of the units provides the necessary flexibility to incorporate different types of filters to deal with specific problems and high levels of other contaminants.

STAGE 1 Bactiguard Pre-Filter:
This is designed to capture the larger particles and thereby extend the life and effectiveness of the secondary filter. A G2–G4 Bactiguard Air Filter, treated to eradicate on contact a wide range of bacteria, moulds, algae and yeasts, is always provided.


STAGE 2 Secondary Filter:
Its purpose is to remove smaller particles, and continue the removal of smaller micro -organisms. Grades from F7-H14 are available, with F8 being supplied in standard models. If the prime contaminant is odorous or gaseous, an Activated Carbon filter designed to enhance this aspect of the unit can be installed.


STAGE 3 Carbon Filter:
Filters of this type are the most effective means of removing odours and gaseous contaminants from the air and form the final stage of filtration.
