About the Laminar flow cabinet/Clean bench

Clean bench is to provide a partial dust-free, sterile working environment of air purification equipment, and the work area has been contaminated air through a dedicated filter access control artificially, to avoid harm to people and the environment, is a safe and clean dedicated microbes table can also be widely used in biological laboratories, health care, bio-pharmaceutical and other related industries, to improve the process conditions, protect the health of the operator, improve product quality and yield are good effect.

Clean bench’s principle: clean environment is in a specific space, clean air (air filter air) flow in the direction set by the formation. To the direction of the air flow points, the existing clean benches can be divided into vertical, from the inside to outside and lateral. From the operation of the quality and impact on the environment to consider, the vertical is superior. The clean air supplied by the air supply filter plate descends through the operating area at a specified speed and is split in the middle of the operating area by the front air suction hole and the rear suction window and the air sucked in at the front and rear of the operating area is mixed Together, and pumped by the blower after the positive pressure zone, in the upper part of the machine, 30% of the gas through the exhaust filter plate from the top of the discharge, about 70% of the gas through the oxygen filter plate to re-enter the operating area. To replenish the air exiting the vent, the same volume of air is replenished from the room air through the service port. These air will never enter the operating area, just form an air barrier.
