Bipolar Ionisation

The Airius PureAir Pearl Series is an air and surface purification and airflow circulation fan system, designed to deliver the highest level of pathogen, particle and odour elimination in any type of indoor commercial or community environment.

Featuring the latest in Needlepoint BiPolar Ionisation technology from one of the world’s leading manufacturers of indoor air quality systems – Plasma Air, the PureAir Pearl Series uses the power of ions to provide continuous round-the-clock sterilisation, neutralising up to 99.9% of all known pathogens, VOCs and odours, in both the air and on surfaces.

The PureAir Pearl also provides all the features and benefits of the world’s most popular destratification and airflow circulation fan, balancing temperatures, improving comfort, reducing heating and cooling costs and cutting carbon emissions.

Cleans The Air & Surfaces

Similar to the PureAir PHI, the PureAir Pearl Series provides both surface and airborne protection.

As natural cleaning ions are circulated into spaces by the PureAir Pearl, their charge draws them to contaminants such as viruses, germs, VOCs or odours, whether these be in the air or on surfaces.When the ions bond they react, neutralising the contaminant rendering it inert, safe and odour free.This combination of industry leading BiPolar Ionisation technology, paired with Airius’ patented columnar laminar airflow circulation, enables the PureAir Pearl Series to circulate its natural cleaning ions throughout spaces more effectively than any competing purification fan manufacturer.

Ion Plasma Field

Manufactured into each PureAir Pearl fan unit is the latest in BiPolar Ionisation technology. By using the power of ions, the PureAir Pearl Series is able to clean spaces in the same way the Mother Nature cleans our outside air.

The integrated BiPolar Ionisation system features two separate emitter points comprising of hundreds of tiny, needlepoint carbon strands, similar to a brush head.During operation an electronic charge is passed through the strands.This creates a plasma field through which each point emits a high concentration of ions, negative from one emitter and positive from the other.These are then circulated into the air via the fan, where they can protect against pathogens, particles, VOCs and odours.

No Ozone

Ozone can be found all around us at both work and home, produced by a wide variety of equipment and substances such as printers, lights, televisions, dishwashers and cleaning chemicals, to name a few.But as with all things, extremely high levels can be harmful.

Airius product ranges are tested to meet and exceed all safety and quality standards, including Ozone. But due to its unique design, the integrated BiPolar Ionisation system within the PureAir Pearl also meets the new UL 2998 product standard, one of the highest Ozone standards possible. This classifies the PureAir Pearl Series as an ‘Ozone Free’ product.

HVAC Savings

Not only does the PureAir Pearl Series provide all the benefits of safe, clean, germ and odour free air, but customers also benefit from the wide range of advantages provided by the world’s most popular destratification fan.

Improved comfort and environment control, reduced energy costs for heating and cooling, a reduction in Carbon Footprints and CO2, are just some of the many benefits from installing an Airius Destratification Fan system. See here for full benefits of Airius Destratification Fans.

Testing carried out by the Spanish Ministry of Defence using MS2 Bacteriophage, an industry standard surrogate for SARS-CoV-2 (COVID-19). Tests conducted in simulated ICU hospital rooms, located within aMadrid hotel converted into a residence and confinement centre for medical staff during the pandemic.

A reduction of approximately 2 log units of the bacteriophage was obtained in the air that was ionized by the Plasma Air system. This corresponds to a 99% reduction after exposure to ionisation.

It is important to note that no medical claims are made.

24/7 Protection

Using the same natural method Mother Natures uses to clean our air, the PureAir Pearl Series circulates positive and negative ions throughout spaces via the fan to provide pathogen neutralisation, particle reduction and odour elimination in any type of indoor environment.

The polarity of the ions attracts them to all particles within the space, causing the particles to cluster together and make them filterable. They also bond with and neutralise pathogens, VOCs and odours by removing them of a hydrogen atom, breaking them down into their basic, harmless and odourless compounds, such as O2, CO2, N2 and H2O.

As these ions are being continuously circulated into the space, The PureAir Pearl Series is providing round-the-clock 24/7 protection, helping to maintain a clean, safe and fresh environment within your building.

Mould, Odours, VOCs

Unpleasant odours can have a significant impact on spaces, whilst mould and VOCs can have serious visual and health implications.In commercial spaces this can have a detrimental effect on your bottom line.

The PureAir Pearl Series with its integrated BiPolar purification system emits charged ions into the air.These ions bond with odour, mould and VOC particles, breaking them down into their basic, harmless compounds such as O2, CO2, N2 and H2O.This reduces or eliminates VOCs, gases, vapours, mould and mould spores, whilst leaving environments smelling fresh and odour free.

Low Maintenance

The PureAir Pearl Series is an extremely low maintenance air and surface purification system, making managing buildings as simple and cost effective as possible.The only maintenance required is to periodically dust the ion emitter brush heads every 3 – 12 months, depending upon the activity within the environment.The fan motor and bearings are all sealed within the unit housing.

All Airius units also come with a market leading 5 year Warranty and 120 Day Money Back Guarantee, providing the confidence you need when making an investment in purification systems.

Outside Air Requirement

Managing air quality within buildings can have a significant impact on comfort, productivity and health. To maintain optimum air quality requires regular circulation of fresh, outside air being brought into the building to dilute, disperse and replace stale, used, dirty air.This cycling of the HVAC system uses energy, which of course costs money and the more frequent the cycling, the more expensive costs.

By installing an Airius PureAir Pearl Series system in your building to clean your indoor air, you can reduce the requirement for outdoor air intake by up to 75%, totalling a saving of approximately 30% on your energy costs.It also helps maintain your HVAC system by keeping coils clean without an expensive UV system, reducing pressure loss.

For Ceilings up to 5.5m

PureAir Pearl Series stand alone fans are ideal for any space with a ceiling up to 5.5m high, where there is a need to clean air, sterilise surfaces and eliminate odours. This makes them suited for a wide range of environments, including Classrooms, Doctors & Dentist Surgeries, Retail Outlets, Offices, Care Homes and many more.

For spaces with higher ceilings the PureAir+ NPBI Series is applicable for ceilings up to 10m. Alternatively, the PureAir Pearl can be used in conjunction with the Airius range of airflow circulation and destratification fans to increase coverage and further circulate its charged ion cleaning agents throughout larger spaces.

Airius engineers can help you select the correct quantity of PureAir Pearl Series fans to service your facility with clean odour free air, as well as balance temperatures and humidity to improve comfort and reduce energy costs.
