GD & GZ Series – Dry Gas Filter Housings
Product Code: GD & GZ Series – Dry Gas Filter Housings

The GD and GZ series, forward flow, dry gas filter housings remove particulate contamination from dry gas including dust, dirt, sand and pipe scale. These filter housings are designed to filter fine particles from gases without excessive pressure differential build-up. Housings are available in vertical (GD series) or horizontal (GZ series) configurations and provide high flow rates at a low differential pressures.

  • Supporting Document (Optional)

The function of Dry Gas Filters (also known as Gas Particulate or Dust Filters), is to remove solid contaminant from natural gas, where no liquid is present. Equipped with high-efficiency synthetic cartridges, this vessel offers an efficient method of filtering small-to-moderate quantities of solids to protect essential equipment in pipeline applications.

Contaminants Filtered by Dry Gas Filters May Include:

  • Catalyst fines
  • Desiccant particles
  • Dust
  • Pipeline scale
  • Sand and silica

Gas Particulate Filters are available in a vertical or horizontal configuration in a wide range of sizes to suit every application.

Natural gas enters the vessel through the cartridge compartment. The flow direction is outside-to-inside through the filter elements, which allows for maximum usage of the filter media. A number of crucial design aspects include nozzle positioning, filter element spacing, pressure drop, nozzle and riser velocity. Positive element seal and riser open areas are important aspects of the design.

Units are constructed to ASME code requirements and can be furnished with a variety of quick opening closures and various
element styles to suit most application.

Major Applications of Dry Gas Filters:

  • Downstream of dry desiccant beds
  • Downstream of catalyst beds
  • Metering and gate stations
  • Fuel gas to compressors
  • Protection of regulators and valves
