Start with the job the filter must do. Then define the fit, medium, performance requirement and operating conditions. A catalogue range is a starting point for a specification, rather than a confirmed replacement part.
Is the task passenger cabin ventilation, engine intake, battery cooling, railway ventilation, building air handling, paint-booth air, industrial dust collection or liquid filtration? Identify the filter stage and existing equipment.
Describe what needs to be retained or adsorbed. Dust, fine particles, odours and suspended solids call for different catalogue functions. Particle capture alone should not be described as gas removal.
Record the overall dimensions, depth, frame or sealing ring, attachment and existing filter reference. Include a drawing where possible. Appearance alone does not establish fit.
Share the flow requirement, temperature, pressure-drop limits and environmental or fluid conditions. Ask the team to confirm the selected medium, grade and technical evidence before ordering.
A cabin filter treats passenger ventilation air. An engine filter treats engine intake air. Their purpose and assemblies differ.
Panel filters use framed pleated media. Pocket filters use extended-surface pockets in an air-handling assembly. Compare the housing, grade, media area and airflow requirement.
The pocket filter in this catalogue is for HVAC and air handling. Industrial bag filters are listed for continuous dust collection. Similar names do not make them interchangeable.
Particle media retain airborne particles. The catalogue describes activated carbon as adding an adsorption function for odours and certain gases. Specify whether one or both functions are needed.
Filter mats are listed for broad pre-filtration and equipment applications. Ceiling filters are described for final-stage filtration in paint, spray and ventilation applications. Match the stage and media grade.
These are distinct dust-collector formats. Confirm the collector attachment, dimensions and medium. Request a cartridge-specific specification to match your equipment.
Filter specifications use ISO 16890, EN 779, EN 1822 and ISO 29463 air-filtration references, as well as micron values for liquid filters. They should be read with the specific product, test method and operating requirement.
Confirm system-specific performance and filter compatibility before ordering. Our team can help specify the selected assembly.
