This document describes the features and characteristics of BELÜFTUNGSFILTER series NBF, BF - WP EDV 02/05, including the dimensions and parameters of different models of filters and filter elements.
This document provides technical specifications for the INTERNORMEN NBF and BF-WP series of ventilation filters. It details the ordering keys for complete filters and filter elements, specifying nominal sizes, filter materials, and connection types.
The data includes dimensional drawings and tables for models ranging from DN 25 to DN 85. Key parameters listed include air throughput (Q), pressure drop (Ap), and mass per unit. The document serves as a reference for selecting the correct filter based on application requirements. This manual is written in German.
| Air Throughput (Q) | in Vmin |
|---|---|
| Pressure Drop (Ap) | ca. 10 mbar |
| Nominal Sizes (NBF Series) | 25, 40, 55, 85 |
| Nominal Sizes (BF-WP Series) | 45, 90 |
| Filter Material (10P) | 10hm Papiervlies |
| Filter Material (3VL) | Abscheideleistung |
| Sealing Material (P) | Perbunan (NBR) |
The pressure drop (Ap) is approximately 10 mbar.
The 10P filter type uses 10 micron paper fleece (Papiervlies).
The standard P designation uses Perbunan (NBR) as the sealing material.
