Custom-built equipment

This area covers replacement elements for filtration equipment built for a specific site: complete filter housings, air handling units, self-cleaning filters and dust collectors. The scope is the consumable — the filter element, its gasket, its holding frame, its collar — and not the equipment itself, nor its installation. Identification works from a measured dimension, from the original drawing or from the element removed, which keeps equipment supplied even when its maker no longer lists the reference. That is the usual case on plant over fifteen years old, where the nameplate has gone and the measured dimension is the only evidence left.
