# CLASS I BIOSAFETY CABINET WITH RECIRCULATION, DOUBLE FILTERING, AND VAPOR AND GAS PURIFICATION – CBK-G MODEL

- Biological safety cabinet type: CLASS I according to EN 12469, with mixed filtration for vapors and gases.

- Compact system that includes filters + ducts + motors within a single unit.

- Designed to provide total protection for the operator and their surroundings while handling microorganisms or biological and chemical products of low and/or moderate risk.

- Work area constructed of galvanized steel with anti-corrosion protection + a layer of anti-corrosion polymeric paint.

- 8 mm opal tempered glass work surface, spill-resistant.

- The air is filtered through **FOUR **stages:

1. G4 pre-filter (90% efficiency) (OPTIONAL)
2. HEPA H14 molecular absolute filter (99.995% MPPS efficiency according to EN1822).
3. Main activated carbon chemical filter for absorption of hazardous gases and vapors.
4. Safety activated carbon chemical filter for absorbing hazardous gases and vapors.

- Continuous filter saturation detection system, located between the filters.

- The CBK Series Enclosures are constructed of epoxy-coated galvanized steel, offering high resistance to chemical corrosion.

- Safety barrier in the work zone where air velocity exceeds 0.53 m/s, with an airflow rate of 220 m³/hr.

- Automatic speed control system with alarms.

- LED and UV lighting.

- Monitoring of speeds, filter saturation level, ventilation level, suction speed…

- The CBK-G Series Booths include alarms for:

Barrier loss due to door opening.

- Loss of molecular efficiency.

- Molecular filter saturation detection

- Decrease in suction speed or motor speed. Ventilation failure indicator.

- Filter expiration and clogging level.

- Detection system expiration

- They are equipped with an internet connection for remote monitoring/control via PC, smartphone, etc.

- Includes a feature update system to stay current with regulatory changes
