Accessories and optionals ………………………… Technical specifications …………………………… Gas flow chart (pressure drop) …………………… Ordering information ………………………………. Standards and approvals …………………………. The FG type is a filter for gas pipelines according to DIN 3386, with very high holding capacity of dust and impurities, suitable for the protections of devices installed downstream. The filters are made of aluminum alloy die-cast, with a wide range for...

ELEKTROGAS – Technical Sheet EE151 – 07/12 The FG type filter is designed for installation in gas lines and compressed air lines, to protect downstream fittings. The filtering cartridge made of nonwoven polypropylene fibers with a metal support frame, is suitable to retain dust and other impurities with size ≥50µm. When the dust storage capacity is exceeded or if there is an excessive pressure difference, the filter loses its protective function. In this case the filter element must be replaced. FGS1-FGS2 models are provided with a mesh filter cartridge, which is easy washable. Figure 2...

ELEKTROGAS – Technical Sheet EE151 – 07/12 Accessories and optionals Inlet and outlet pressure chambers can be provided with pressure gauges, to connect a gas differential pressure switch to monitor the pressure difference. On request a test point fitting can be provided (mounting in charge of the user). Technical specifications Gas threaded ISO 7-1 from Rp1/2 to Rp2 Flanged PN16 – ISO 7005 from DN65 to DN150 Ambient temperature Flow capacity Pore width of filter element Filtration class Pressure gauges (when provided) Inlet and outlet chambers G1/8 onto threaded models (except FGS1-FGS2)...

ELEKTROGAS – Technical Sheet EE151 – 07/12 When the flow read on the diagram is referred to operating pressure instead of standard conditions, the pressure drop ∆p read on the diagram must be multiplied for the factor (1+ relative pressure in bar): Example: 3 In the 2” filter with an air flow of 100 Nm /h there is a pressure drop ∆p = 4 mbar. 3 If we consider that 100 m /h is the flow at 2 bar of inlet pressure, then the pressure drop to be consider is: ∆p = 4 x (1 + 2) = 12 mbar Filter must be selected considering the following: - Pressure drops ∆p ≤ 10 mbar Flow velocities w ≤ 20 m/s...

ELEKTROGAS – Technical Sheet EE151 – 07/12 Ordering information Additional code none= without pressure gauges (no drilled) A= screw plug 1/8" at the inlet and outlet (except FGS1-FGS2) K= special seals for aggressive gases A= screw plug 1/4" at the inlet and outlet K= special seals for aggressive gases Example: FGS42.A for a filter with Rp11/2 threaded connections, Pmax= 2 bar, small size and screw plug at the inlet and outlet. Test point fittings must be order with their ordering code. Manufacturer reserves the right to update or make technical changes without prior notice.
