The Kojair KC-1 safety cabinet provides a safe working chamber for the operator and environment alike when handling hazardous materials. All work inside the safety cabinet is performed via the work opening. Air is constantly being removed, which prevents contaminated particles reaching the operator's breathing zone.

This safety cabinet has an opening through which the operator can manipulate the objects it contains, air being continuously exhausted to prevent the escape of airborne contamination generated inside. The air flow in this safety cabinet is not laminar.

Technical information

Construction
The safety cabinet interior is constructed of stainless steel.

Window
The front window is made of laminated 6 mm thick glass, and can be sealed for fumigation and opened for ease of access to the work space.

Finishing
All internal finishes are solvent, disinfectant and abrasion resistant, and the base flat and rigid, preventing it from flexing which might create dangerous conditions inside the cabinet.

Lighting
The illumination of the work surface is 1,000 lux.

Filters
The main filter is a leak-tested, high efficiency HEPA-filter which meets the requirements of standard H14, i.e. an efficiency of at least 99.995% for particles with an average diameter measured according to MPPS. The filter is mounted in such a way that no air can by-pass the filter medium.

Exhaust system
The safety cabinet is constructed to exhaustair into the atmosphere using an individual fan mounted downstream of the filter. The fan is virtually silent and voltage regulated. The safety cabinet is fitted with an automatic anti-flowback system downstream of the filters to prevent air flowing back inside, particularly when the fan is switched off.

Air velocity
The safety cabinet is designed to ensure that the air velocity at all points of the working aperture remains within the specified limits, a minimum of 0.7 m/s.

Noise level                                                                                                                  
The noise level is approximately 53 dB(A).                                                          

KC-1 safety cabinet fulfills the requirements of standard EN-12469.
