S@femate TOTAL Cabinets have been designed according to the airflow specifications for NSF49 Class II Type B2 cabinets, also known as 'total exhaust'. 100% fresh air is taken in from the lab, either from the front aperture and from a main inlet. The air from the main inlet is then cleaned by the main HEPA H14 filter to provide an ISO5 working area and joins with the air from the front aperture on the bottom of the cabinet. All the air is then circulated behind the backwall of the unit and filtered via the exhaust HEPA H14 filter and reinjected into the environment.

• Sloped front sash (5°)
• Swinging front window for optimal clearing access
• Maximum height of front aperture: 440 mm
• Front sash in stratified safety glass, 6 mm; Exhaust connector: diameter 315 mm
• Front window presses on the gasket when in closed position to ensure no leakages
• Sliding sash with electrical operation and auto recognition of the correct work position
• Front grid with 'V' shape to avoid obstructing it with the arms. No need to use armrests
• Filter replacement and electric/electronic components maintenance from front side
• External surface in epoxy-painted steel
• Internal sockets with IP 55 protection level

This kind of units are designed to be hard ducted and provide the possibility to work safely with small amounts of chemicals without the risk of increased concentration due to the air recirculation.

Working chamber and work surface fully realized in stainless steel AISI304 with SB finishing. Easy to clean as required by EN 12469:2000. Work surface divided in sectors, available both solid or perforated.

Air decontamination provided by HEPA H14 filters, with efficiency >99,995% (test MPPS according to EN 1822.1). DOP test port for easy check of HEPA filters integrity.

Constant monitoring of the following parameters: Laminar flow speed; Inflow speed; Optical/acoustic alarm for insufficient inflow barrier; Optical/acoustic alarm for insufficient laminar flow; Operating hours visualisation for: cabinet, HEPA filters, UV.

Volt-free contact for remote blower control or connection to a remote alarm system.
