DELTA series absolute lters for duct ows LLMB - KKMB Technical features Product Efciency MPPS Suggested nal pressure drop Maximum pressure drop Maximum operating temperature Maximum relative humidity ATEX version on request DELTA series LLMB - KKMB absolute lters are designed to work with high ow rates, 35% higher than other similar lters of equal size; at nominal air ow, they work with a frontal air speed of 2.00 m/s. This allows to reduce the size and the cost of ducts as well as the occupied space. Furthermore, compared to standard lters, due to the limited pressure drop, operating life is longer and there is a higher energy saving level for the fan motor. These lters have mini pleated microber glass ltering pack, top quality manufacture, high dust holding capacity and great mechanical resistance. The frame of these lters is available in two different materials: MDF wood (LLMB) and galvanized steel (KKMB). Both the models have a special expanded polyurethane single piece gasket. All lters are tested individually and labeled as a guarantee of the measured features. LLMB models are fully incinerable. Also available in H14 efciency: LLMA model and KKMA model (CE and ATEX certied) Initial pressure drop LLMB - KKMB Product ready in Stock / *1 m3/s x 10-3 = 1 l/s Typical curves Technical draft Nominal air flow rate %
