Filter Engineering

Filter technology is becoming ever more advanced as the demands for environmental and product protection increase. The correct selection of an air filter for a given application requires an understanding of both filter engineering and the regulations governing its use.

The diagram on the left shows how the overall efficiency of a particulate filter is the result of a combination of 4 basic filtration mechanisms (sieving, inertia, interception and diffusion).

General Ventilation The correct selection of an air filter for general ventilation (air supply into offices, shops, work places etc) is critical if running costs are of concern. The filter life cycle cost is often not considered, but can have significant impact on the total running cost of a plant. Most air-handling systems (old and new) are fitted with poorly specified filters that can more than double maintenance costs. We offer a free life cycle cost analysis service.

Clean Process - Product Protection When air cleanliness is a requirement for an industrial or medical process the air filter system employed is of paramount importance. The use of high efficiency particulate air (HEPA) and ultra low penetration air (ULPA) filters is now widespread. Working in partnership with the worlds leading filter manufacturer we are able to supply, install and validate to the highest standard.

Hazardous Processes - Operator Protection

Health and safety is assured in both the workplace and the external environment by the removal and control of many different contaminants discharging from commercial, chemical and industrial processing.

Activated carbon filters possess the ability to remove a wide range of odours, gases and chemical vapour contaminants from air streams. Utilising different grades of activated carbon, high contaminant removal efficiencies are possible in critical applications.

HEPA filters are widely used to remove toxic or bacterial particles with efficiencies greater than 99.999%.

Tecomak has considerable experience with safe change filter systems, originally designed for the nuclear process industry but now widely used in hospital isolation units and research containment laboratories.
