DELTA series DAB - DAA absolute lters are mini-pleated, with very high
ltration efciency; DAB lters belong to HEPA class, whereas DAA lters
belong to ULPA class.
They are made of a mini-pleated glass ber sheet with continuous thermoplastic separators. It is xed to the frame by means of a polyurethane
sealant. The medium is protected by white epoxy painted micro-drawn
steel protection grids. It is provided with a semi-circular expanded polyurethane one-piece gasket. DAB - DAA lters have a robust construction,
high quality and moderate pressure drops which assure a long operating
life and a limited energy consumption of the fan in the AHU. All the lters
are individually tested through a scanning system to make sure there are
no pinholes in the medium; at the end of the test they are labeled with
the test results.
