DELTA series ABH-AAH absolute filters are minipleated and of limited depth, studied for applications in unidirectional air flows areas.

The ABH models are made in a wide range of sizes with air flows from 150 to 2260 m3/h. All the filters have an extruded anodized aluminum frame, with micro drawn white epoxy painted protective grids. The filtering medium is made of micro-fiber glass, water-proof and fire resistant; the mini pleats have continuous thermoplastic spacers, the sealant is polyurethane elastomer. It has a one-piece gasket positioned in its own seat.

Thanks to the low pressure drop of the filters, the energy consumption level of the fan is very low. All filters are tested individually and carry a label indicating the performance levels.
