Fresh Air Curtain Recommendation
• Try to create a laminar flow over the test area.
• Curtain should cover the entire test area (test hood or sample point) and extend at
least 0.5 m outside the area.
• Air speed in curtain should be rather low, typically 0.1 m/s.
• Additional small fan(s) can be set up within the curtain for directional purging of test
chamber etc.
