Spray booths are manufactured in galvanised steel that’s double folded for stiffness and consist of paper baffles, which are folded into a concertina form and collect 80-90% of the dry overspray dust to leave the chamber behind clear of wet paint fumes. Air is drawn back through the dry back spray booth whereby any airborne paint droplets stick to the paper.
In HSE ‘HSG140: Safe Use and Handling of Flammable Liquids’ guidance, it states that: there should be sufficient ventilation where flammable liquids are being handled to dilute any released vapours to a safe level, below the applicable workplace exposure limit. However, where there is not sufficient ventilation, mechanical ventilation, through the form of local exhaust ventilation is required.
HSE HSG276: Isocyanate Paint Spraying guidance states: “Isocyanate paint mist is invisible and breathing it in can cause occupational asthma:” However, Yale School of Medicine state: “If occupational asthma develops, attacks can are triggered in a variety of environments; not just by isocyanate exposure."
Auto Extract Systems offer a wide range of dry back spray booths (or also commonly known as extraction chambers) in various sizes and can be assembled as part of a modular system to meet your fume extraction requirements.
Maintenance is simple, as part of on-going maintenance regimes, with disposable filters only taking a few minutes to replace. Filters are made from either andrea paper filters, up to three tiers tall or fibreglass soil and strip filters.
This type of spray booths 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.
