Gasfilter GFK

Product catalog summary

Overview: The document is a product brochure for GFK gas filters, designed to protect downstream devices from blockage, offering high throughput, purification efficiency, and a long service life. The filters are easy to maintain with replaceable filter pads and are EC type-tested and certified.

Applications: GFK gas filters are suitable for filtering fuel gas and combustion air for all gas-consuming appliances. They are used in pressure control systems and main gas shut-off devices.

Product Range: The brochure lists various models of GFK filters, including GFK..R, GFK..F, and GFK..T, with different specifications for each model. Examples of order codes are provided for clarity.

Technical Specifications:

Gas Type: Suitable for natural gas, town gas, LPG (gaseous), biologically produced methane, and air.
Max Inlet Pressure: Varies by model, up to 6 bar for certain models.
Ambient Temperature: -15 to +80°C (5 to 176°F).
Housing Material: AlSi for GFK 15 to 100, sheet steel for GFK 125 to 250.
Connections: Various connection types including Rp internal thread, flanged, and NPT.
Filter Pad: Made from polypropylene fleece, standard 50 µm.

Maintenance: Filter pads should be changed annually, or biannually for biologically produced methane, or if the pressure differential doubles from the new state, with a maximum Δp of 20 mbar.

Contact Information: For further details, contact Elster GmbH, with contact details provided in the document.
