Introduction

Users often have a large choice when selecting a safety cabinet and may be confused by the multitude of features and design styles which are offered.

This article adopts the point of view that no safety cabinet design is perfect and seeks to independently and objectively explain the pros and cons of each design style, so that the user may make his or her own assessment in deciding which cabinet is more suitable for his or her own application and ergonomics.

Adjustable stable airflow is the fundamental for biosafety cabinet operation. Biosafety cabinets must maintain airflows at designed parameters. To do this a speed controller is used to vary the voltage to the blower motor. Increasing or decreasing the voltage to the motor directly increases or decreases the motor speed or rpm. In turn the fan attached to the motor increases or decreases the speed of the air moving within the cabinet. The most common speed controller used in biosafety cabinets is a phase cutting electronic speed controller. These types of controllers are commercially available at reasonable prices and due to their robustness are practical to implement in various cabinet designs. (more…)

When selecting potentially power-consuming equipment, such as a biosafety cabinet, the key to face those problems is energy saving. Esco’s solution to the abovementioned problems is to provide energy efficient product lines, such as the Airstream Class II and Labculture Plus Class II biological safety cabinets. (more…)
