Extract ventilation air hygiene assessment

Guardian Water Treatment provides air hygiene assessment services across the public and private sector. Air hygiene assessments are essential for getting a clear picture of the overall condition of extract ventilation and ductwork in the likes of kitchens, offices, hospitals and schools.

Guardian’s air hygiene assessments cover the condition of the extract ventilation system, the ease of its access and deposit limits and the Wet Film Thickness Test (WFTT), as detailed in B&ES TR/19.

Guardian is also able to offer specific recommendations to ensure a system runs at its optimum, including advising on the frequency of cleaning, based on system usage.
