Structure
The purification workbench is composed of cabinet, fan, high-efficiency filter, operation switch and other major components. The cabinet is made of cold plates, etc., the surface is sprayed with plastic, and the worktop is made of stainless steel. The purification unit uses a fan system with adjustable air volume. By adjusting the working state of the fan, the average wind speed in the clean work area can be kept within the rated range, and the service life of the high-efficiency filter is effectively extended.
working principle
The air passes through the primary effect filter, is pressed into the static pressure box by the centrifugal fan, and then filtered through the high-efficiency filter and then blown out from the air outlet surface to form a clean airflow. The clean airflow flows through the area to be purified at a uniform cross-sectional wind speed The dust is taken away, thereby forming a high-cleanness working environment.
Install and use
The working place of this workbench should be in a clean working room (preferably placed in the primary purification room of 100,000 or 300,000 class), plug in the power supply, and turn it on according to the function shown on the control panel. Before starting the machine, the work surface and the casing of the purification station should be carefully cleaned to remove surface area dust. Normal operation can be carried out ten minutes after the machine is turned on.
maintain
1. According to the actual use situation, the primary effect filter is removed and cleaned regularly, and the cleaning cycle is generally 3-6 months. (If it is not cleaned for a long time, dust accumulation will affect the insufficient air intake and reduce the cleaning effect.)
2. When the air filter of the primary effect filter is normally replaced or cleaned, and the ideal cross-sectional wind speed cannot be achieved, the working voltage of the fan should be adjusted to achieve the ideal uniform wind speed.
3. Generally, when the working voltage of the fan is adjusted to the highest point after using the eighteenth, and the ideal wind speed is still not reached, it means that the high-efficiency filter has too much dust accumulation (the filter hole on the filter material has been basically blocked, and it must be updated in time) In general, the service life of high-efficiency air filters is 18 months.
4. When replacing the high-efficiency air filter, please pay attention to the correctness of the model specifications (original manufacturer configuration), according to the arrow wind direction device, and pay attention to the seal around the filter, absolutely no leakage occurs.
