The Circulaire® Laminar Flow Hoods offer clean air to ISO Class 4 using U15 ULPA particulate filters for the very best in product protection. To achieve Laminar Flow within a Laminar Flow Cabinet air is initially drawn through an easy-change, high-quality EU4 pre-filter to remove all gross particulate.

Turbulent flow then passes through the fan system, before being pushed through an ULPA or HEPA filter removing 99.9998% of all particles 0.12 μm in size. This in turn expels the air in a laminar flow and guarantees an ISO Class 4, particle free working environment, providing the best product protection.
