Clean bench is in order to adapt to the modern industry, optoelectronic industry, biological pharmaceutical and scientific research experiments in areas such as the demand for local work area cleanliness. Its working principle is: through the fan in air, through the plenum through high efficiency filter, purify air will be filtered in vertical or horizontal airflow status is sent out, make the operation area continue to reach the level under the control of the clean air cleanliness, ensure the production on the environment cleanliness requirements.
1. Horizontal laminar flow hood
: it is a kind of general local clean bench, it is widely used in electronic, national defense, precision instrument, instrument, the pharmaceutical industry, etc.The box to choose 1.5 thick high quality cold-rolled steel plate static electricity spraying processing (or stainless steel), stainless steel countertops, centrifugal fan with high quality, the United States Dwyer differential gauge, early and efficient two-stage filter, level manifolds, open platform, easy to operate, equipped with a universal wheel, can move with meaning;And a variety of models can be customized according to customer's actual demand.
2. Vertical laminar flow hood
: laminar flow hood is widely applied in need local clean area. Laboratory, biological pharmacy, photovoltaic industry, microelectronics, hard disk manufacturing and other fields. laminar flow hood with high cleanliness, can be connected into the assembly line, low noise, mobility, etc. The box to choose 1.2 thick high quality cold-rolled steel plate electrostatic spraying processing (or stainless steel), stainless steel countertops, centrifugal fan with high quality, have the single side, double side a variety of models, can be customized according to customer's actual demand.
Now all the workbench can satisfy the experiment you need, you need to consider is air flow pattern (according to your experiment watch that supply air form for your least affected) : is the vertical or horizontal. Are generally in vertical. Vertical air supply is vertical downward blowing, vertical manifold, mesa of closed type, which can effectively prevent external confluence seductive odor and stimulation to the human body. And ensure that the airflow can't stop them, if put microscope in the workbench, the vertical air supply air flow will be blocked by microscope, choose level are better, but usually with vertical experiment and glass doors are generally move up and down. Sometimes the level of impact alcohol lamp flame.In plain English two kinds of air supply there is no obvious, or select the appropriate type according to the experiment of the most important.
