Filter Designs was formed as a Limited Company in 2001 by Roger Callis. Roger alone had over 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 (EAF) in Leicestershire. He quickly established a business that led the way in the dust control industry.
This experience was shared with the present employees of the business to continue the benefits of industry knowledge. In 2012 his son, Simon Callis, continued leading the day-to-day operation of the business as Managing Director, with Roger retaining an active role as Chairman.
In late 2021, Roger sadly passed away. He left behind a thriving engineering business, with a tight-knit and talented team. This is his legacy, and the team continue to honour this by delivering projects for clients all over the world.
Filter Designs continue to be 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 of 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.

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.
