With over 25 years’ experience in the building services Richard’s answer was a resounding “Yes”.

RAB works with many partner companies including AJM Ventilation, a ductwork installer with fully trained and highly experienced pairs able to cover any aspect of this contract.

The problems were:

• 10 of the supply ducts were drawing air from high level louvres.

• Access required scaffold access which would make future maintenance very difficult.

• Internal access was also a problem meaning that the duct would have to be split.

• The location was a hospital and much of the work had to be completed at weekends.

Liaising with distributor GVS Filtration and their client a successful bid was put forward in a competitive tender and we subsequently fully surveyed all 28 locations.

Most of the filters were fitted onto the outside of the AHU louvre intakes where they could be easily accessed and cleaned. The high-level louvres presented a slight difficulty.

The solution – split the supply duct and install new purpose manufactured filter frame sections (AJM) complete with RABScreen withdrawable filters (RAB).

Now the local airborne debris created by London’s A40 and the surrounding industrial area could be kept away from the disposable filters increasing their lifespan by as much as 60%. This front-line protection allowed the introduction of the highly efficient GVS BACTICELL, which also improves efficiency and can cope with higher pressure differentials between changes.

The partnership of RABScreen and BACTICELL will reduce filter replacement costs dramatically with the next filter change not expected until August 2019.
