Introduction:
The clean bench is designed to meet the needs of modern industry, photoelectricity industry, biopharmaceuticals and scientific research and testing on the cleanliness of the local working area. The air is sucked into the pre-filter through the fan, and then filtered into the high-efficiency filter through the static pressure box, and then the filtered air is sent out in the state of vertical or horizontal airflow, so that the operation area reaches the cleanliness of Class 100 to ensure the production of the environmental cleanliness requirements.

Classification:
According to the number of operators: divided into one-person clean bench and two-person clean bench.
According to the direction of airflow can be divided into vertical laminar flow ultra-clean bench and horizontal laminar flow ultra-clean bench. Vertical flow clean bench due to the fan at the top so the noise is greater, but the wind is blowing vertically, more in the pharmaceutical engineering so as to ensure the health of people; horizontal flow clean bench noise is relatively small, the wind direction is outward, so it is mostly used in the electronics industry, which has little impact on health.
According to the operating structure is divided into single-sided operation and bilateral operation of two kinds.
According to its use can be divided into general clean bench and biological (pharmaceutical) clean bench.
Note: Clean bench and biological safety cabinet is different. Clean bench can only protect the reagents operated in the bench from contamination, and does not protect the staff, while the biological safety cabinet is a negative pressure system, which can effectively protect the staff.
Commmon dimensions:
Cleanliness | Laminar flow type | Air velocity | Noise | Power supply | External dimensions (W×D×H) | Woking area (W×D×H) |
Class 100 | Horizontal | 0.45~0.75 m/s | ≈50dB | AC,1φ -220V/50HZ | 1250×650×1750 | 1000×800×1450 |
Vertical | 1170×600×800 | 960×600×600 |
Applications:
Clean bench is a kind of unidirectional flow air purification equipment which provides local dust-free and sterile working environment.
It is suitable for the scientific research and production departments which need local clean and sterile working environment, such as medicine and health, biological medicine, food, medical science experiment, optics, electronics, aseptic chamber experiment, aseptic microbiological test, plant histoculture inoculation and so on.
Clean bench has the characteristics of low noise and movability. Its use to improve process conditions, improve product quality and increase the rate of finished products have good results.

Precautions:
The length of service life of the clean bench is related to the cleanliness of the air.
In the temperate regions of the clean bench can be used in the general laboratory, however, in tropical or subtropical areas, by the atmosphere contains a lot of pollen, or dusty areas, it is advisable to place the clean bench in an indoor area with double doors.
In any case, the air inlet hood of the clean bench should not be placed against an open door or window, so as not to affect the service life of the filter.
