Filtration Systems

Details

Bag and cartridge filter housings remove suspended particles from compatible process liquids. Bag systems suit a range of general particle-removal duties, while cartridge choices allow the media type and stated retention performance to be matched more closely to the process. Single-element, multi-element and multi-bag arrangements depend on flow, contamination loading and service intervals. Housing materials, seals and connections must suit the liquid and operating conditions. Replacement enquiries should identify element dimensions, end fittings and the required filtration efficiency. A micron label alone is insufficient: the specified retention basis and test information should be checked for the selected element.

For selection: Liquid and concentration; Flow and contaminant loading; Retention efficiency and test basis; Pressure and temperature; Connection standard; Element size and seal material

Pipeline strainers capture larger particles before they reach sensitive downstream equipment. Basket and duplex arrangements can be selected around the maintenance access and continuity required by the process. Where solids loading or operating patterns justify it, automatic backwashing and mechanically cleaned filters provide alternative ways to remove collected material. Selection depends on particle characteristics, fluid viscosity, available pressure and the acceptable pressure loss. The cleaning method also affects utility requirements and the discharge or collection arrangement. Replacement baskets, screens, seals and cleaning components should match the original model and specified aperture rather than an assumed universal equivalent.

For selection: Flow and fluid viscosity; Solids size and loading; Screen aperture; Permitted pressure drop; Operating pressure and temperature; Cleaning utilities and discharge arrangement

Compressed-air filtration uses different stages to address particles, liquid droplets, aerosols and selected vapours. Water separators remove bulk entrained liquid, coalescing elements capture fine liquid aerosols, and particulate filters retain solid contamination. Activated-carbon stages may be specified for suitable hydrocarbon-vapour removal duties. Each stage must be selected for the required outlet quality and actual operating flow, pressure and temperature. Filters do not replace a dryer where a controlled pressure dew point is required. Supply enquiries can include housings, matched replacement elements, drains and differential-pressure accessories. Claimed air-quality classes require confirmation for the complete selected treatment arrangement.

For selection: Actual air demand and reference conditions; Minimum operating pressure; Temperature; Required air quality; Existing treatment stages; Connection and drain requirements

Hydraulic and lubrication filters control particulate contamination in machinery fluid circuits. Product families include return-line, suction and in-line filters, with spin-on, in-tank and duplex formats available for appropriate duties. Filter location, fluid viscosity and temperature influence the required element and housing arrangement. Selection should also consider the target cleanliness level, element efficiency, bypass arrangement and pressure conditions, rather than nominal micron size alone. Enquiries can cover complete assemblies or replacement elements for existing equipment. Part numbers, housing identification and the fluid specification help establish compatibility; seals, indicators and other service components are matched to the selected filter assembly.

For selection: Hydraulic or lubricant fluid type; Flow and viscosity range; Pressure and temperature; Target cleanliness and efficiency; Bypass requirements; Housing model and element part number
