About Us | Plasma Clean Air

From the launch of our first commercial kitchen odour control solution, the Xtract 2100 back in 2008, plasma-cleanair have established ourselves as a market leader and expert in air, odour and grease control.

From hospitality to healthcare, plasma-cleanair provides products and services to keep our customers air clean

Steering that mission is our CEO, Steve Keogh, who brings more than 20 years of strategic and commercial experience to the business. Having worked across global organisations and ambitious SMEs, Steve has built a career on driving growth and leading teams with clarity and purpose.

Before joining Plasma Clean Air, Steve held senior Sales and Marketing Director roles within the security sector, where he honed his expertise in building customer-focused solutions and scaling commercial operations. He studied Business Management at Salford University and expanded his leadership skillset at Ashridge Management College, giving him a strong foundation in both strategic thinking and practical execution.

Since taking the helm at Plasma Clean Air, Steve has accelerated the company’s growth trajectory, expanding both product innovation and service delivery. Under his leadership, the business has achieved sustained, measurable growth through a combination of organic sales success and targeted acquisitions.

Today, Steve continues to guide Plasma Clean Air with a forward-thinking, customer-first approach—ensuring we remain a trusted leader in clean air technology for commercial kitchens, data centres, indoor environments, and beyond.

David Glover is the founder and Technical Director of Plasma Clean Air.

From the very beginning of his career, David has been driven by a passion for tackling environmental pollution and improving the spaces where people live, work and eat.

He holds a doctorate in environmental microbiology from the University of East Anglia, where his research focused on microbial pollution control. This was followed by post-doctoral work at the University of Aberdeen in microbial diagnostics, giving him a deep scientific foundation that continues to shape Plasma Clean Air’s innovation today.

Since 1996, David has worked across the UK technology sector, partnering with multiple university-led start-ups and helping transform cutting-edge science into practical, real-world solutions. At Plasma Clean Air, he leads all R&D, product development and service innovation, with specialist expertise in commercial kitchen pollution control, Indoor Air Quality, infection control and wellness technologies.

And when he’s not immersed in tech? You’ll likely find him on a yoga mat or meditation cushion. David lives and breathes wellness—bringing both scientific rigour and personal passion to Plasma Clean Air’s mission of cleaner, safer air for everyone.
