Factair are specialists in the provision of temporary tunnel ventilation and monitoring services to the rail industry.

Renewal and maintenance work in tunnels can often generate levels of dust and pollution which exceed EH/40 Workplace Exposure Limits. Frequently locomotives, generators, diggers and bulldozers can all be operating within the same confined space. In addition, activities such as ballast handling often creates excessive levels of dust which needs to be cleared from the worksite.

Factair has been providing temporary tunnel ventilation and environmental monitoring systems to the rail industry since 1992. Their modular fan systems can be rapidly deployed with minimal disruption and wherever possible these are deployed outside the tunnel adjacent to the portal, thus causing no obstruction to traffic.

Factair’s team of Engineers undertake regular atmospheric monitoring to ensure levels remain within the EH40 limits which are recorded, a report is provided at the end of the contract.
