Xiamen Horizontal Flow Clean Workbench

The principle of horizontal flow purification workbench is that the clean environment of the purification workbench is formed by the flow of clean air (filtered air) in a specific space according to the set direction

Principle of horizontal flow purification workbench　
The clean environment of the purification workbench principle is formed by the flow of clean air (filtered air) in a specific space in a set direction. According to the direction of airflow, existing ultra clean workbenches can be divided into vertical, inward outward, and lateral types. From the perspective of operational quality and environmental impact, vertical design is superior. The clean air provided by the gas supply filter plate descends through the operating area at a specific speed, separates in the middle of the operating area, and is sucked away by the front air suction hole and the rear suction window. The air sucked in from the front and rear parts of the operating area is mixed together and pumped into the rear positive pressure area by the blower. In the upper part of the machine, 30% of the gas is discharged from the top through the exhaust filter plate, and about 70% of the gas enters the operating area again through the oxygen supply filter plate. To supplement the air discharged from the exhaust port, the same volume of air is replenished from the room air through the operating port. These air will never enter the operating area, they just form an air barrier.

Purification workbench purpose

Purification workbench is widely used in medical and health, biopharmaceuticals, food, medical science experiments, optics, electronics, sterile room experiments, sterile microbial testing, plant tissue culture inoculation, and other scientific research and production departments that require a locally clean and sterile working environment. It can also be connected to an assembly production line with advantages such as low noise and mobility. It is an air purification device that provides a locally high cleanliness working environment with strong universality. Its use has good effects on improving process conditions, enhancing product quality, and increasing yield.

Characteristics of Purification Workbench

1horizontal flowThe purification workbench adopts a vertical flow manifold and a quasi closed tabletop, which can effectively prevent external airflow from entering and the stimulation of human body by operating odors;2. Adopting an adjustable air volume fan system, the voltage is adjusted by a touch sensitive switch to ensure that the wind speed in the working area is always in the ideal state; 3. The workbench is made of 304 stainless steel material.Classification: Purification workbenches are divided into single person workbenches and double person workbenches based on the number of operators, and are structurally classified into conventional and new push-pull and self circulating circular types.
