General ventilation systems capture residual, warm fumes and gases that are emitted from the process.
A main feature of the general ventilation systems captures residual, warm fumes and gases that are emitted from the process and have risen vertically towards the roof, which haven't been caught and directly removed at-source. The general ventilation system continuously removes polluted air that settles just below the roof, roughly two or three metres below. An additional benefit of this system is that it still allows for any vehicles or gantry cranes to operate within the building.
By installing a high-level general fume extraction system not only creates a cleaner, safer work environment for all staff in the business but also provides cost savings; rather than trying to extract the entire volume of the building we target the dirty band of fume that can be visibly seen with multiple extraction points.
In HSE’s WL3: Welding Fume Control guidance, it states that: “Effective general ventilation provides rapid fume clearance as is necessary to minimise the fume build-up from over the shift where welding fume is not fully removed by local exhaust ventilation (LEV). Mechanical general ventilation is typically required because natural ventilation (from through-draughts) is not sufficient enough to disperse the fume generated.”
Auto Extract Systems can help specify and design the right LEV system for your business's requirements. We only use the highest quality products and installations come complete with a 12-month installation warranty.
General ventilation systems should be utilised in conjunction with one of our centrifugal fans to vent the captured fumes either directly to the atmosphere or depending on the working process, via a filtration unit.
