Westbury Filtermation

What Westbury Filtermation does

Westbury Filtermation Ltd is a UK-based manufacturer of air filtration products and provider of related indoor air quality services, headquartered in Burnley, Lancashire. Founded in 1969, the company designs and produces a broad filter range — HEPA (H10–H14), panel, bag, rigid, and carbon filters — alongside containment filtration systems for nuclear and pharmaceutical applications, and operates manufacturing capability including a Glasstech bag filter line, robotic welding, and FRAM injection moulding. Since being acquired by Deltrian in February 2026, the company sits within a 18-entity international filtration group, extending its reach into power generation, automotive, offshore, and pharmaceutical containment verticals via products such as the RPV98 ESN nuclear-grade filter launched in March 2026. Sister company Total Filtration (acquired September 2018) adds liquid filtration and marine-sector capability.

The business operates a multi-segment B2B model selling directly into facilities management, healthcare, catering, and containment customers, while also serving the UK education and public sectors through the NWUPC (2023) and CPC (September 2025) procurement frameworks. Revenue mechanics combine manufactured filter product sales with recurring service revenue from duct cleaning, fire damper testing, kitchen extract cleaning, and TR/19 grease cleaning compliance. The company markets technical expertise and standards compliance (ISO 16890, EN 1822, ISO 9001/14001/45001, Avetta, EcoVadis) as core go-to-market differentiators, supported by a Burnley-based sales office and London satellite location. No AI or software-driven revenue layer is evident across the product or service portfolio.

Scale signals (101–250 employees, in-house manufacturing, multiple framework memberships, and integration into a 18-entity global group) position Westbury as a mid-sized industrial filtration specialist with diversified end-market exposure but no disclosed revenue or growth trajectory to substantiate financial scale claims.
