Headline vapour adsorption cartridges comprise inner and outer filter tubes with the space between filled with adsorbent. The cartridges are sealed with nylon end caps.

Headline vapour adsorption cartridges are designed to fit all standard size filter housings to provide vapour adsorption over the full range of line pressures.

Flow rates are the same as for grade 50 elements in the same size bodies. However, with adsorption, more important considerations will be the volume of adsorbent and the contact time.

Headline Disposable In-Line Adsorbers consist of nylon bodies filled with granular adsorption material with integral inlet and outlet filter pads. Four sizes are available, containing from 6cc up to 120cc of adsorbent.

Flow rates are the same as for grade 50 elements in the same size bodies. However, with adsorption, more important considerations will be the volume of adsorbent and the contact time.

A range of adsorbent materials is available, and these are detailed below.

Headline Intermediate and Large Disposable In-line Filters are available in two-port or three-port configurations for particulate and coalescing applications respectively. Where running cost is more important than initial cost, plastic housings with replaceable elements should be considered.

Large DIF’s are also offered with threaded ports （1/4”NPT）: simply add 1/4”NPT to the product code.

Headline Filters range of Disposable In-Line Filters consists of permanently welded housings with encapsulated filter elements. This makes them ideal for portable analysers and other analysis systems requiring a robust and easily replaceable filter. A choice of body materials makes them suitable for a wide range of chemical environments.

The units on this page are designed for particulate removal applications. For coalescing and bypass filtration duties, the DIF-INxxC, DIF-LNxxC and DIF-LKxxC should be considered. Where running cost is more important than initial cost, plastic housings with replaceable elements should be considered.

The ‘xx’ in the part number should be replaced with the grade required, e.g. DIF-N70, DIF-MN40.

PTFE filter elements are produced by sintering pure PTFE granules, no other substances are used in the construction. These filter elements are usually offered when only 100% pure PTFE can be used. It is normally preferable to offer a K type disposable filter element, if suitable, as both pressure drop and life characteristics are superior to the PTFE elements. The advantage of PTFE is a higher maximum temperature, up to 200°C, and somewhat better chemical resistance. These filter elements should be ultrasonically cleaned to give best results.

Stainless steel filter elements are made up of several layers of 316 mesh that are sintered together to form an integrated porous element. The middle mesh is of very fine gauge and determines the filtration efficiency of the elements. This layer is then overlaid with inner and outer layers of coarser mesh, to give support and protection.

The elements are a typical surface filter and the contaminants are retained on the surface of the filtration layer, this makes cleaning and back flushing a simple process. These filter elements should be ultrasonically cleaned to give best results.

Stainless steel filter elements are particularly useful in heavily contaminated applications and for use as pre-filters before disposable type final filters. Gaskets are required with stainless steel filter elements. The options are Viton, PTFE or high temperature annealed copper.

Headline disposable filter elements are manufactured from precise mixtures of borosilicate glass microfibres, to the very highest standards of quality control. These elements offer exceptional filtration efficiency at very low pressure drops and, being 90+% void volume, give very long service life.

The elements are self-gasketing and easily sealed into the housing by axial compression.

The elements are bonded to impart high strength and eliminate fibre shedding. The choice between the different binders available will depend upon the application conditions.

Particulate Removal Applications

Standard elements are suitable for all particulate removal applications in non-corrosive gases. The coarsest grade that will adequay protect the application should be chosen, as this will result in the most economical solution to the contamination problem.

K Type are specified where corrosive gases and liquids are to be filtered, as they have excellent chemical resistance. They are also used where highly reactive gases are being analysed, since they exhibit very low levels of adsorption.

S Type are compley inorganic and are used at temperatures up to 500ºC or if solvents are present.

Coalescing Aerosol Removal Applications

C Type elements are specifically designed for the removal of liquid aerosols from gases in both corrosive and non-corrosive applications. These elements also remove particulates with the same efficiency.

Filter Element Efficiency

Each element type is available in a wide range of grades of efficiency, covering the complete range from coarse bulk contamination removal （grade 80） and the essentially complete removal of submicron particles （grade 40）.

Filter Element Dimensions

All disposable filter elements have a part number arranged with three figures, e.g. 25-64-70C. The first part refers to the inside diameter of the element in millimetres, the second figure refers to the overall length of the element in millimetres and the third part refers to the grade designation. Replace the ‘xx’ in the part numbers listed below with the grade designation.

Standard Size

Special Sizes

Special size filter elements are manufactured in a range of diameters and lengths.
Inside Diameters - 10mm to 100mm
Lengths -              10mm to 1000mm
