Many industrial processes create odours, material recycling facilities, RDF plants, waste to energy, abattoirs, pet food manufacturers and food recycling are all common problem industries.

Odours are quickly created by bacteria and volatile organic compounds generated from decomposing matter. Fogging, misting or scrubbing systems do not clear odours and masking fragrances can smell worse than the odours they are meant to cover. Furthermore, these systems are expensive to maintain and have punitive ongoing chemical and water costs.

Using Fortress Air’s AIRsteril advanced UV technology the Mega Thermal units offer a scientifically proven solution for around-the-clock control of odours. In addition to eliminating odour problems, the AIRsteril technology constantly reduces pathogens in the air and on surfaces providing a healthier and infection controlled work environment for all.

One of our largest UK projects to date was a waste transfer station of 12,000m2 which processes over a thousand tonnes of household waste a day. They received in the region of five hundred odour complaints a month from local residents. After AIRsteril units were installed there was no exterior odour detectable and all genuine complaints were eradicated overnight.

The AS Range has been specifically designed for small spaces such as bedrooms with continuous occupation, it is ideal for residents who suffer heavy incontinence. It does not have a fan making its silent thermal convection operation a favourite with residents and staff who may be disturbed by noisy machines in their rooms. It uses a standard wall socket and once installed, an AS unit runs continuously requiring just one annual lamp change.

The MF Range is designed to control odours in medium to large sized enclosed spaces. It is ideal for reception areas, corridors, dining rooms and resident’s lounges. The units are installed to suit the size of space (20 sq m to 100 sq m) and the level of contamination, they are fan driven and operate 24/7. Once installed they can be easily tweaked to achieve the optimum level of performance and an MF unit requires minimal maintenance and one annual lamp change for years of operation.

The WT Range uses the latest thermal convection UV technology to control high levels of odours in smaller enclosed spaces such as sluice rooms, washrooms and any rooms where there is non-continuous occupation. The units are hard-wired to an existing power source such as a lighting circuit spur to operate 24/7. In sluice rooms, the footfall tends to be quite low but there can be a rapid build-up of odour as contaminated items are processed and waiting collection.

Our groundbreaking AIRsteril technology is guaranteed to help you:
– Improve cleanliness by removing all odours.
– Improve infection control for residents, patients, staff and visitors.
– Improve air quality especially for residents with respiratory problems.
– Cut the need for cleaning chemicals and perfumes.
– Extend the life of soft furnishings.
– Cut staff turnover and absenteeism.
– Improve first impressions for new clients and families.
– Comply with regulations.


On a Test Match day at Lord’s there are 25,000 people, mostly males, spending all day watching cricket and drinking. With several visits per person during the day the gents toilets can have up to a 10,000 footfall a day. The staff have had difficulty in clearing the resulting odours. The stainless steel trough urinals in some of the washrooms create added problems.

Just in time for a major Test Match, AIRsteril WRX trial units were installed in two of the major washrooms. After just a few hours, the units had managed to get on top of the smell, then controlled the odours throughout the 5 day match. The facilities staff are very pleased and plan to increase the number of installations before the start of the next cricket season.”
