Ventilation Services

If you have a ventilation system that provides a controlled environment to protect a product or control hazardous emissions from a process, we can provide ventilation testing, repairs and maintenance for you.

We offer a complete range of performance verification tests including air change rate measurements, room differential pressures checks, sealability testing, airflow visualisation and biological sampling. If you have a contamination issue we offer a room biological decontamination service.

As well as testing and validation services to ensure compliance and safety, we offer a full ventilation system maintenance and repair service, minimising the chance of costly breakdowns and safety hazards.

Ventilation testing and maintenance can be arranged to a regular schedule under contract, or on an ad hoc basis, depending on your requirements. Contract customers benefit from full asset management and reminder service, minimising admin overheads, as well as free telephone consultancy.

Local Exhaust Ventilation (LEV)

As part of our LEV service, we carry out statutory LEV COSHH testing for all types of system, providing you with easy to understand documentation. We also carry out a full range of mechanical and electrical maintenance, repair and upgrade services.

We can design, install and maintain all types of local exhaust ventilation including fume cupboards, microbiological safety cabinets, isolators and bespoke fume and dust extractors.

HEPA and Carbon Filtered Systems

Efficient filtration is at the heart of many types of ventilation system, so having the right filters correctly installed is critical to the overall performance of your system. We supply and install all types of filters, and make a point of bringing replacement filters with us to carbon and HEPA filter testing and maintenance visits, so we can replace them instantly, minimising facility downtime.

Containment Level 3 & 4 Laboratories

We have over 20 years’ experience servicing containment laboratories that handle the most hazardous of pathogens, ensuring the safety of workers and the wider public.

Engineering & Production Sites

Cutting and processing metals, plastics, timber or other materials can all generate hazardous levels of fumes and airborne particles which can be hazardous to human health. We can install appropriate fume extraction systems to protect workers, ensuring safe disposal of smoke and particulates. Our LEV service includes advice on the appropriate frequency of testing and maintenance of systems exposed to heavy use, in order to keep production running smoothly and safely.
