Ventilation and Environmental Monitoring Services 

Engineering work within confined spaces, including disused tunnels, can frequently generate levels of dust and pollution, which exceed the Workplace Exposure Limits listed in HSE document EH40. These spaces can also present their own inherent biological hazards that must be considered when designing a suitable ventilation scheme and safe system of work. Factair has extensive experience in the design of innovative ventilation systems. The company has developed and installed a varied range of temporary systems at a diverse number of locations including: London Underground, theatres, disused tunnels and underground fuel tanks. 
Whatever form your confined space comes in Factair can help you develop a safe system of work. For the more complicated projects this includes an initial site survey to assess the hazards and potential pollutants present. When this assessment is combined with the activities being undertaken in the space, the number of air changes required per hour can be established.  
Factair can provide equipment on a hire only basis or as a complete installed set-up with atmospheric condition monitoring and environmental report at the end of the project. Factair is a RISQS audited supplier to the rail industry and its rail tunnel ventilation equipment is Network Rail approved. 
Factair has a comprehensive selection of ventilation fans available for hire. These range from 300mm, 110V to 1200mm, 380/415V all available with matching wire reinforced anti-static ducting. 
1280 and 1740mm diameter self contained rapid deployment engine driven fans. 
Where electrical power is not available Factair can offer for hire air driven fans for hire in 300 or 600mm diameter sizes. 
As well as intrinsically air powered fans Factair offers 300mm Zone 1 electrical fans. These robust units are constructed from 304 stainless steel and feature an innovative carrying handle that helps to protect the STAHL isolator. All units are also fitted with a 5m electrical cable and STAHL plug as standard.
