About Us

A little bit about us

Filter Designs was formed as a Limited Company in 2001 by the present Chairman, Roger Callis. Roger alone has 45 years experience in the industry including pioneering Ceramic Filter Technologies, a position as Technical Director for Lodge Sturtevant and an apprenticeship at DCE, then establishing Environmental Air Filtration in Leicestershire, Roger is well placed to serve the dust control industry.

This experience is shared with the present employees of the business to continue the benefits of industry knowledge. Since 2012, Simon Callis has dealt with the day to day operation of the business as Managing Director, with Roger in a supporting role.

We are a family run engineering business who specialise in hot gas filtration for industries worldwide. Turnkey plants are our core business, delivering filter systems with ceramic elements, filter bags or cartridges to a variety of industries.

These turnkey jobs can include various facets; ducting, filter system, insulation and cladding, ID fan, chimney, Continuous Emissions Monitoring (CEMS) systems, controls, SCADA systems, electrical cabling, sodium bicarbonate dosing (deSOx), activated carbon dosing, selective non catalytic reduction (SNCR) for reduction of oxides of nitrogen (deNOx), ash storage in bulk bags, hoppers, silos and associated lean or dense phase conveying ot tanker loading and offloading.

Specific experience includes filter systems for secondary aluminium, minerals processing plants, glass furnaces, cement plants, bio-ethanol production, asphalt plants, steel furnaces, carbon plants, quartz production, clay pigeon manufacturing, syngas systems, woodwork machinery, precious metals, coal boilers, fire simulators, spice manufacturing, sludge incineration, plastics manufacturing, brick plants, waste to energy and combustion and incineration plants dealing with biomass, RDF, clinical waste and municipal waste.

Systems have been deployed across the globe, from local projects all over the United Kingdom from Swansea to Fort William. Overseas projects include systems delivered to China, Boston and Florida in the USA, Singapore, Finland, Azerbaijan, Czech Republic, Poland. Filter Designs team are often working with larger companies who are delivering total process plant, where our role is to help deliver the flue gas cleaning plant for a new process.

However, we have also completed plastic separation plants, plastic presses and been involved in numerous minerals and aggregate processes at lower temperatures involving cartridge filter systems and ducting and hood design to current legislation.

We are currently signed up to a number of non-disclosure agreements involving interesting and pioneering projects. In the past we have worked on innovative R&D projects creating bio ethanol with a filter under positive pressure, a tyre pyrolysis plant with air and water quench systems, world first bespoke dust collection systems

Filter Designs are ISO 9000:2015 accredited which means that we manage our quality control through a system of checks which feed back into our processes for the purpose of continuous improvement.

Filter Designs rise to the challenges posed by these projects to deliver working solutions, which all require clean gases to atmosphere to protect our shared environment.

Our recent Projects

We were contracted to provide 2 small Ceramic filters suitable for a small volume but with a design maximum temperature of 600°C. In addition the filters will be handling a syngas which cannot be mixed with oxygen so an alternative to compressed air would need to be used for the ‘Cleanpulse’ cleaning of the 25 Ceramic element in each of these CPC78 filters. In addition dosing of small amounts of a re-agent is required so the client also opted for a ‘Cleandose’ 25kg bag skid. Find out more about Project CAD below.
