Filter Wall

Wall of air filters for nuclear air inlets and air ventilation

AAF’s Filter Walls are installed into the inlet of nuclear power plant buildings or rooms which need a high flow rate. They can also be used to provide filtered ventilation air. This can be used to ventilate a backup diesel engine, allowing air to circulate freely around the engine and in doing so removing excess heat generated.

An AAF Filter Wall can also be installed into existing Walk-in Filter Housings to permit the highest flow rate filtration stages. The dimensions and specifications are fully customisable. The filter wall can be fitted with pre-filters or high-efficiency filters, on one or both sides. The unit can even be equipped with a handling platform to facilitate maintenance.
