  Steril – Powder Safe

  This POWDER SAFE cabinet is a vertical laminar flow in ISO 5 Class according to ISO EN 14644-1 @ 0,3 and 0,5 m particles size (Class 100/M3.5 according to Federal Standard 209E). The cabinet is designed with part of air recirculated and part of air exhausted outside the equipment through H14 HEPA filters (according to EN 1822).
  The operating cycle described above together with an inflow air barrier assure a slight depression and, therefore, isolation from the surrounding area.
  Application
  The identified and carefully estimated factors considered as essential, with particular reference to process and safety requirements, are:
  • protection of the product;
  • protection and safety of the operator;
  • containment of handled product;
  • cleanness of working area;
  • ergonomic factors.
  The operator and the environmental protection and product safety from cross contamination are obtained by appropriate flows permanently monitored by a microprocessor automatic control system.
  The operator and the environmental protection are achieved exhausting 40% of air through an HEPA filter. This maintains the cabinet in negative pressure and creates an air barrier of more than 0,40 m/s. The recirculation of the remaining 60% of the air on the working area in laminar air flow condition at a mean 0,30 m/s through another HEPA filter guarantees the cleanness of the working area, avoiding cross contamination and any perturbation or dispersion of dust.
  Moreover the specific construction of the cabinet, special fixing devices on the fan together with a marble anti-vibration support (optional) allow the use of balance for measures up to 0.01 mg.

  Steril – VBH Compact

  VBH Compact cabinets produced by Steril are designed to fulfill and satisfy the European Norm EN12469 and country standards (presently superseded by EN12469) like German DIN 12950/10, French NF44-201 and English BS 5726.
  VBH Compact cabinets are manufactured with a frontal working opening for the aspiration of 30% of the total air involved, at a minimum velocity of 0,40 m/s, and the remaining 70% is recirculated through a HEPA filter in the working chamber with a mean laminar flow velocity of 0,40 m/s (as defined by European standard EN 12469: 2000). The containment index, evaluated on the total surface of the front working opening, corresponds to APF (Aperture Protection Factor) equal or more than 1 x 105 according EN12469. The microprocessor monitors in real time all critical parameters of the unit (laminar air flow velocity, exhaust flow rate and position of the front screen) and controls the optimal function of the fans even if in presence of effects caused by progressive clogging of the HEPA filters.
  TECHNICAL SPECIFICATION
  Work chamber and spillage tray in stainless steel AISI 304L “2B” finishing. Working surface in stainless steel AISI 304L “2B” finishing, removable and autoclavable in perforated and solid version. Hinged front window, in laminated safety glass; ergonomic opening 150°. Maximum free height with open screen: 540 mm. Full vision height of 535 mm at operational condition. Ergonomic front closure panel in anodized aluminium complete of germicidal UV lamp. Lighting on working surface by means of 2 fluorescent electronic lamps fitted in non-contaminated area. Construction structure in steel epoxy-polyester powder painted. Ventilation system by means of n°2 IP55 protection factor motor blowers. Recirculating and exhaust air filtration achieved by H14 HEPA filters as per EN 1822 (with efficiency 99.995% MPPS). Maintenance completely from the front of the cabinet.
  SAFETY DEVICES
  Microprocessor monitoring with alarms of the following parameters:
  Exhaust flow rate out of the pre-set range;
  Laminar air flow velocity out of the pre-set range;
  Front window in wrong position;
  Fans failure.
  STANDARD ACCESSORIES

  OPTIONAL ACCESSORIES
  PC interface for monitoring and remote servicing with lithium battery.
  Double HEPA exhaust filter.
  Activated carbon exhaust filter.
  Support stand.
  Chest of 3 drawers on pivoting wheels.
