Performance Examples

ScandMist Performance Example 1

This major automotive engine manufacturer, with arguably the most advanced plant in Europe, had issues with their existing, group-preferred oil mist system. Although these systems were only a couple of years old, the performance results came as a complete shock when surveyed.

Performance of their existing oil mist filtration system:

• Inlet: 5.790 mg/m³ 
• Outlet: 5.703 mg/m³ 
• Efficiency: 1.5%

Vokes Air manufactured a bespoke retrofit ScandMist body, consisting of just two stages (it was not possible to fit a HEPA stage)

Performance of the ScandMist two-stage system:

• Inlet: 5.516 mg/m³ 
• Outlet: 0.034 mg/m³ 
• Efficiency: 99.3% 

The graph above highlights the difference in the performance of the two systems.

ScandMist Performance Example 2

The second graph (below) shows the performance of a standard three-stage ScandMist 400 D unit, installed at a prestigious European engine manufacturer. The ScandMist unit was attached by ducting to two Grob machines, which were machining cylinder heads using emulsion.

Over the three years that the test was conducted, no filter changes were required or performed.

• Average Inlet: 28.3 mg/m³ 
• Average Outlet: 0.001 mg/m³ 
• Efficiency: 99.999%
