Air Intake Screen Installation: University In The South Of England


To install a filtration solution to prevent airborne debris from entering air intake systems without negatively impacting upon airflow.

We were asked to attend site and carry out a full survey of the existing AHU and chiller plant. Surrounded by trees and greenery, a range of issues are caused on site by pollen, leaves and associated airborne debris.

Airborne debris restricts airflow by clogging filters and chiller coils, causing plant to work at a greater duty. In order to achieve requisite airflow, energy consumption is increased.

This site has few maintenance engineers with limited time. Coils must be regularly cleaned and filters changed due to high volumes of airborne debris is labour intensive, valuable maintenance time is consumed.

Restricted airflow creates increased strain upon plant. This, combined with rigorous cleaning regimes means that plant life is reduced.

Work carried out:

We recommended the installation of air intake screens. Designed to fix over external intakes on AHUs, chillers, condenser units and cooling towers, air intake screens have minimal impact upon airflow whilst offering excellent filtration qualities.


“Now that we have had the Air Intake Screens fitted for a period of approximately six months, we have had time to review their effectiveness against debris. I am pleased to say that they are working very well and have enabled the service engineers and our own onsite maintenance to be able to clean off the chillers and air handling units quickly and easily. This has saved a considerable amount of work as filters and cooling batteries are no longer becoming clogged.

These have proved to be extremely effective and I would not hesitate to have these fitted to other plant in the future.”
