Four elements to consider when choosing a clean bench

1. Classification of purification workbenches

According to its airflow direction, it can be divided into horizontal one-way flow purification workbench, vertical one-way flow purification workbench, and non-unidirectional flow purification workbench.

Horizontal one-way flow purification workbench: The filtered clean air is blown directly to the operator from the back to the front. It is a local purification workbench with strong versatility. It is widely used in electronics, precision instruments, and pharmaceutical industries.

Vertical one-way flow purification workbench: vertical flow refers to the filtered clean air blowing from top to bottom to the ultra-clean table, and then blowing out the ultra-clean table back and forth. The vertical flow purification workbench is usually used in laboratories, biopharmaceuticals , electronics and other fields.

They are classified according to the operation mode. The purification workbench can be divided into: single-person single-sided purification workbench, single-person double-sided purification workbench, double-sided single-sided purification workbench, double-sided purification workbench, three-person single-sided purification workbench Clean bench, etc.

2, the filter of the purification workbench

The filter that has the greatest impact on the price fluctuation of the purification workbench is the filter, which directly affects the cleanliness and service life of the purification workbench.

Of course, the service life of the filter is related to the cleanliness of the air and the frequency of use of the purification bench. In temperate regions, the purification bench can be used in general laboratories. However, in tropical or subtropical regions, due to the high amount of pollen in the atmosphere, or the dusty areas, the purification bench should be placed in a better room with double doors. use. Under no circumstances should the air inlet hood of the purification workbench face an open door or window to avoid affecting the service life of the air filter.

3. Materials for purification workbench

The appearance of some purification workbenches is more delicate and novel, and the stainless steel material used is better, so there will be a higher cost on the shell. For example, some purification workbenches are formed by stamping a whole piece of stainless steel plate at one time, without welding, and easy to clean.

4. The fan of the purification workbench

The fan and filter of the 100-level purification workbench represent the technical level of the product. Therefore, the fan is also a component that distinguishes the price. A good purification workbench usually uses an imported fan. This fan has low noise and low vibration, so that the operator can conduct experiments in a quiet environment without affecting the normal operation of the experiment.
