La Cabina de Seguridad Biológica Clase III ofrece un nivel absoluto de seguridad que no puede alcanzarse con las cabinas de Clase I y Clase II. Todas las cabinas Clase III suelen estar fabricadas con construcción metálica soldada, diseñadas para ser herméticas al gas, y el trabajo se realiza a través de puertos de guantes en la parte frontal de la cabina. Durante el funcionamiento habitual, se mantiene una presión negativa respecto al ambiente exterior dentro de la cabina, lo que constituye un mecanismo de seguridad adicional en caso de que se vea comprometida la contención física.
En todas las cabinas Clase III, el aire de escape se filtra mediante HEPA y se incinera. Los materiales se transfieren al interior de la cabina mediante una unidad de paso instalada en el lateral del área de trabajo.
Las cabinas Clase III suelen expulsar el aire de vuelta al laboratorio; sin embargo, el aire también puede expulsarse mediante un sistema de conductos dedicado hacia el ambiente exterior. Cuando se emplea un sistema de conductos dedicado, estas cabinas también son adecuadas para trabajar con productos químicos tóxicos como complemento de procesos microbiológicos.
Características imprescindibles a considerar:
- Los filtros ULPA de doble escape ofrecen mejor protección que los diseños de una sola etapa
- Sistema de control fácil de usar
- Guantes de una sola pieza en Neoprene™, probados contra fugas, para garantizar la máxima protección.
- El paso integrado con puertas de enclavamiento permite la transferencia de materiales sin riesgo de contaminación ambiental.
- El frente angulado de la cabina asegura una postura de trabajo cómoda.
- Manómetro Magnehelic montado en la parte posterior de la zona de trabajo para un monitoreo sencillo
- Alarmas audibles y visuales para notificar al usuario condiciones inseguras
- Recubrimiento en polvo Isocide™ que inhibe el crecimiento microbiano
El controlador de microprocesador Sentinel™ Silver cuenta con una pantalla LCD de una línea para mostrar el estado del flujo de aire y la hora. Dispone de teclas táctiles suaves para el ventilador, la lámpara, el enchufe y la lámpara UV. La cabina emitirá alarmas audibles y visuales ante eventos no deseados.
El controlador de microprocesador Sentinel™ Gold cuenta con una pantalla LCD de cuatro líneas para mostrar simultáneamente el estado del flujo de aire, la velocidad del flujo de aire, el enchufe, la ventana frontal, el modelo de cabina y la hora. Dispone de teclas táctiles suaves para el soplador, la luz y la lámpara UV. La cabina emitirá alarmas audibles y visuales ante eventos no deseados.
El sistema de control HMI supervisa todas las funciones y monitorea el rendimiento de la cabina en tiempo real. Cuenta con una gran pantalla LCD gráfica para mostrar los parámetros de funcionamiento del aislador. Existe un paquete de alarmas disponible para usuarios con requisitos más avanzados.

All Class III biological safety cabinets are suitable for work with microbiological agents
assigned to biosafety levels 1, 2, 3 and 4. These BSCs are frequently specified for work involving
the most lethal biological hazards.
Class III BSC may be used with or without a ducting system.
Due to the nature of work that is typically conducted in a Class III BSC, ducting the biosafety cabinet provides an additional layer of protection. Installing a ducting system means that there is no recirculation of air inside the laboratory keeping the operators and environment safer from biohazards.
Biosafety cabinets is an airflow containment device designed for handling biohazardous agents. BSCs provide sample, personnel, and environment protection. Typically, EN12469 and NSF 49 are the standards used as references.
Isolators are containment devices for sterile drug compounding that offers product protection. Isolators are designed with negative
pressure to provide personnel and environment protection. USP 797 is used as the guiding principle for isolators.
No, the gloves are not autoclaveable. When cleaning or disinfecting the gloves of Airstream® Class III Biosafety Cabinet, Esco recommends the use of 70% isopropyl alcohol.
The front glass of Airstream® Class III Biosafety Cabinet is constructed from 8 mm tempered glass. Tempered glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering creates balanced internal stresses which cause the glass, when broken, to crumble into small granular chunks instead of splintering into jagged shards. This property makes tempered glass safer and likely to cause lesser injuries.
a. The blower static pressure needed / how many Horse Powers of the blower needed = 150 pascal, recommended exhaust fan PP025 0.34kw (0.5 HP)
b. The recommended flow rate = 603 cmh
c. The recommended diameter of duct to be used = 8 inch round duct.
d. The structural loading and electrical connections should be sufficient for AC3 requirements.
e. The biosafety cabinet should be subjected to gaseous decontamination prior to moving it to the new location.
f. The biosafety cabinet should be re-certified after installation in the new site is completed. Risk assessment is strongly recommended prior to any relocation to ensure hazards are reasonably identified, risk evaluated, and all issues are mitigated accordingly.
The Airstream® Class III Biosafety Cabinet (AC3) is builty with safety in mind. It features:
An air-tight design - completely welded construction to ensure absolute containment for operator and environmental safety
Dual exhaust ULPA filter - which creates a ISO Class 3 workzon and offers 10 x better filtration efficiency compared to HEPA
Magnehelic pressure gauge - mounted at the rear zone for easy monitoring
Airstream® Class III Biosafety Cabinet (AC3) uses a microprocessor-based control system. It supervises all cabinet functions and has a large display of the cabinet's parameters. The control system also features easy-to-use keypads.
Yes, Airstream® Class III Biosafety Cabinet (AC3) complies to EN 12469 requirements.
Yes, Airstream® Class III Biosafety Cabinet (AC3) is equipped with a disposable and non-washable polyester fiber pre-filter with 85% arrestance / EU3 rated.
The estimated shelf life of HEPA or ULPA filters is up to 10 years when stored properly.
Filters should be kept in their original packaging and should not be exposed to dampness, excessive heat, cold or rapidly changing temperatures. These filters can tolerate up to 95% humidity; anything higher can cause the filter media to block and fail.
