Filter Manufacturers

Filter Services
we offer

Customers approach BEC at different stages of the filter manufacturing process; some need to change moulders and have a filter and design ready to go, others need assistance in material selection and some guiding through a design from start to finish. We are here to help at any and all stages, advising on design and material selection, prototyping with 3D printing, tooling, and filter encapsulation.

Our site in the South of the UK produces hundreds of thousands of filters for our clients every year. Customers often visit the factory to discuss current and new projects – allowing us to work closely together to design innovative new filters and ensure the quality of current production is up to scratch.

Our Filters

Filters are chiefly used to protect part of a machine– be it a car engine, the heating element of a tumble dryer or the plumbing in your home. A robust filter keeps the machine working for longer.

At BEC, we produce filters for air, oil, water, and solid materials. Using depth-media, non-woven, stainless steel, plastic and sintered meshes ranging from 10 micron to 2000 micron. These plastic encapsulated filtration devices are shipped around the globe, to the Czech Republic, USA, and Germany.

What industries
we work in

Initially producing filters for household goods such as tumble driers and kettles over 40 years ago, BEC has since expanded into manufacturing filters for marine, automotive, domestic, and biomedical applications.

We supply tens of thousands of filters to leading automotive manufacturers every week, for both domestic and large commercial vehicles. We work closely with these clients to develop bespoke filters to fit strict requirements in tough environments.

Our ISO 9001:2015 certification demonstrates our dedication to outstanding customer service and providing consistently high-quality filters to our customers. Our work in serving the automotive industry reflects our ability to keep to tight deadlines and strict quality requirements.

How are BEC filters made?

Manufacturing a filter begins with a tool design for the finished product. Once the mould tool has been produced, a filter mesh is loaded onto a metal core, the steel mould tool closes around it, plastic is injected into the tool and around the filter mesh, encapsulating it in a plastic moulding to create a support frame for the filter.

Post-moulding most filters require some type of secondary operations, be that trimming of excess plastic around the filter, or the more complex ultrasonic welding. Ultrasonic welding involves joining two parts of a filter together through high-frequency vibrations and force. This produces a strong, tight seal without a visible seam.

What materials are they made from?

BEC predominantly moulds filters in nylon, polypropylene or polyester due to their chemical stability in air, oil, and water. Depth-media, non-woven, stainless-steel, plastic and sintered meshes are used, ranging from 10 to 2000 microns.

Material selection is dependent upon the environment and material to be filtered- air permeability, the durability of the filter, and whether it can be cleaned or replaced all need to be taken into account. As keen innovators our research and development department are always happy to help with new and difficult projects, including those using recycled plastics or bioplastics.
