Headline

Headline filter housings and elements are suitable for a wide range of gas filtration applications for both particulate removal and coalescing of liquid aerosols.
Applications include:-

  • Protection of Gas Analysers
  • Vehicle Emission Analysis
  • Flue Gas Analysis
  • Sample Protection
  • Fast Loop/By-Pass Filters
  • High Pressure Filters
  • Corrosive Gas Filters
  • Sample Conditioning

To select the correct filter you should consider the following:-

  1. Pressure and temperature of the gas at the filter housing.
  2. Chemical and physical composition of the gas.
  3. Contaminants to be removed.
  4. Type of filtration duty: Inlet, particulate, coalescing, fast loop.
  5. Flow rate, line size and level of filtration required.
  6. Relative importance of cost, response time, ease of service and interval.

Items 1,2 and 3 will determine the materials of construction of the filter housing, including element and seals. Filter housings are available in a wide variety of materials, to ensure there is a product in the range for even the most specialised applications. As well as our range of standard materials, a wide range of exotic materials is also available to special order.

Item 4 will determine the configuration of the housing, one port for inlet filters, 2 ports for in-line housings and 'T' housings for particulate filtration, and three ports for coalescing or fast loop housings.

Items 5 and 6 will establish the most appropriate size of filter. There is always a compromise between those factors favouring a small filter (fast response time, smallest space requirement, lowest cost, minimised adsorption losses) and those factors favouring a large filter (long service intervals, low pressure drop). The exact choice will therefore depend on the relative importance of these factors in each particular application.
