Application, characteristics, technical data Application Type DF 50 filters are intended to separate gas impurities such as dust, rust, and other solids in gas-carrying line at a defined point. They are mainly used in gas systems and in front of such devices whose function is impaired by contamination. These filters can be used for gases according to DVGW worksheet G 260/G 262 and for neutral non-aggressive gases. (other gases on request) Easily replaceable filter cartridge High separation efficiency thanks to optimized flow guidance (30 µm standard, 5 µm optional) Type of models / Options...

Structure and function The gas flows through the inlet flange into the filter housing. The dust particles entrained in the gas are retained by the filter element. The cleaned gas flows off through the outlet flange. The filters mainly consist of the housing, the cover, and the filter cartridge. Taking off the cover for maintenance and replacement of the filter cartridge guarantees easy access. The filter cartridge is made of non-woven polypropylene fibers, is equipped with a metal support frame and is suitable for holding dust and other impurities with a size >= 30 µm (>=5 µm optional). If...

Design If the flow rate read from the diagram is based on the operating pressure instead of the pressure at standard conditions (p=1.01325 bar, t=15°C), the pressure drop read from the diagram must be multiplied by the following factor: (1+ relative pressure in bar) Example: With a filter of size Rp1½" and an operating natural gas flow of 80 Nm3/h, the pressure drop according to the diagram is ∆p = 2 mbar. If this 80 Nm3/h flow is at 2 bar, then the effective pressure drop must be calculated as follows: ∆p = 2 mbar*) x [(1 + 2)x1/bar] = 6 mbar *) Determined from the diagram The filter must...
