Air Flow Visualisation / Clearance Testing

Spray booth clearance test

One of the easiest ways to evaluate the performance of your spray booth extraction system is to use a fog machine for a fog clearance test.

One of the largest causes of occupational asthma is from chemicals called isocyanates and these chemicals are commonly in associated with spray booths.

The HSE (Health and Safety Executive) and the MVR (Motor Vehicle Repair) have a requirement for operators of spray booths to measure and display clearance times to meet the requirements of COSHH (Control of Substances Hazardous to Health).

The Concept Colt 4 fog machine is a powerful hand held fogger that allows users to rapidly fill spray booths. The unit is designed to create a dense white fog that is extremely persistent. For larger spray booths Concept recommend the Spirit 900 fog machine.

Localised air flow visualisation

Fog machines are incredibly useful when conducting localised air flow visualisation tasks in fume cabinets, HVAC systems etc.
