AURA MiniTM Cabinet is made in Italy for Cruma by Euroclone under the brand Bioair and is supplied in one compact size only (895 mm). These state of the art compact down-flow cabinets, provide an ultimate cleanliness Class 100 work area where the highest safety for the products is achieved. The internal design, the air flow aerodynamics, the special H14 filter and the Filtrete®exhaust filter (or prefilters) guarantees the highest performances at the most stringent safety levels and operator comfort. Two operating modes are available: inward air barrier and outward air barrier. INWARD air barrier. In this configuration an air barrier flows through the front opening and is recirculated with the downflow air by a motor blower. 70% of the air is returned to the work area through the main HEPA filter and 30% is exhausted into the environment through a Filtrete®exhaust filter with gravimetric efficiency of 99% on 3μm particles. In this configuration an excellent product protection is ensured, aswell as an outstanding containment. OUTWARD air barrier. In this case the air is sucked through the Filtrete®prefilter, mixed with the incoming recirculating air and then filtered through the main HEPA filter into the work area: here 30% of the air is exhausted through the front opening and 70% is recirculated. This configuration ensures the highest product protection. In the INWARD configuration this unit can easily be used as an “active PCR” cabinet for DNA carry over blocking.
