High Efficiency Filter Bags - OA series

The OA series filter bags have a high oil and hydrocarbon adsorption capacity, and are available rated at 1-25 micron, at particle removal efficiencies >90%.

The filter bag has 3 or 4 layers depending on micron rating, and includes a central polypropylene microfibre layer with enhanced oil and hydrocarbon adsorption properties, and an outer cover to eliminate fibre migration and give added support to the filter media. It is constructed with sewn seams, with a choice of any ring type, including our Welseal Polypropylene collars.

Originally designed to remove silicones and fluorocarbons from electrocoat paints in the automotive industry, like all our filter bags, the OA series is manufactured under silicone free conditions.

The OA series has excellent particle removal efficiencies, and therefore is not only used in applications requiring the oil absorbent properties of the filter media. For example, the OA series is well suited to applications requiring an increase in filtration efficiency compared to using standard 1-25 micron felt bags which perform to an efficiency of around 60% or industrial filter cartridges.
