A recent example of this is the Olympic sized swimming pool at the University of Bath. The client required increased fan output. 
Air Systems advised on options and provided the necessary costings for equipment and labour. The pool was closed for refurbishment so that work could commence. 
The motor and drive gear was replaced. 
Coils, filters and frames were cleaned and where necessary treated by removing rust and re-painting. The work had to be carried out in confined spaces with limited access and to meet the client’s deadline. Please see the before and after pictures below.
