Aura Vertical S.D.4 is a partial-recirculating Class 100 vertical laminar airflow: air coming through the front aperture is mixed underneath the work surface with the downfl ow air and recirculated. AURA VERTICAL S.D.4TM Cabinets are supplied in one dimension (1.2mt). The internal design, the air flow aerodynamics and monitoring, the special H14 filter with Micromesh downstream equalising plenum, guarantees the highest performances at the most stringent safety levels and operator comfort.
70% of the air is returned to the work area through the main HEPA class H14 fi lter (provided with micromesh membrane for perfect air speed distribution) while 30% is exhausted into the environment through the exhaust HEPA class H14 filter.
Both HEPA (H14) fi lters are manufactured and DOP tested according to standard EN 1822-1: 99.995% overall collection effi ciency on 0.1-0.2 μm (MPPS).
This ensures product protection as well as operator and environment protection against non-pathogenic materials (i.e.: allergenic aerosols, powders, etc.).
Thanks to the HEPA (H14) fi ltration the airflow inside the cabinet (constant average speed 0.45 m/s) guarantees Class 100 (FED STD 209E) - ISO5 (ISO 14644-1 Standard) environment in the work area.
The special sloped front design and the sliding sash ensure comfortable working position and, when needed, a very easy opening and closing of the front window.
A complete and user friendly tool for the protection of highly sensitive products that only experienced European design with over 35 years of know how and accurate quality manufacturing, can provide.
