 2. Working principle

The negative pressure suction dust collection box is based on the principle of ai convection and negative pressure ventilation, and the airflow generated by the operation of the fan is introduced into the diversion channel (that is, the operating area). Through the airflow

the large particles of dust fall into the dust collecting drawer under the action of gravity, and the fine particles and dust-containing gas enter the filter chamber from the filter element of the dust collecting drawer ,and the effect of automatic dust collection is achieved. At the end of the operation, manually pull the dust collecting drawer to clean, and the fine particles entering the filter chamber can be cleaned from the dust exhaust hole by tilting the dust box to both sides; if the dust particles adhere to If the other surface of the box body is scattered on the fan, the dust particles can be blown into the filter chamber by means of spray gun, and finally cleaned out from the dust exhaust hole.

3. performance characteristics

1.'Using high-efficiency centrifugal fan, special noise reduction treatment, so that the wind is more stable and the operation is quieter;

2. Imported ultra-clear acrylic see-through window +12V built-in LED soft light belt to protect eyes and be safer;

3.Red and green two-color split control switch,which can be controlled as needed, saving time and improving efficiency; 4. The anti-leakage protection device protects electrical appliances and avoids damage, making the operation worry-free throughout; 5.Drawer-type filter element collects dust and double-filtered, which is fast and convenient for dust discharge, which is more conducive to the physical and mental health of the operator;

6.The aluminum alloy sandblasting and oxidation design of the whole machine is light and small, easy to place, simple to connect, and can meet the collection and cleaning of different types of dust 4.safety tips

1.Before using for the first time, check that the filter element of the dust cllecting drawer is not covered by the protectiv film, and that the dust exhaust holes on both sides of the box are not blocked by other obstacles.If so, please remove it before use;

2. If sandblasting is required in the dust colection box, please place an isolation board at the bottom of the box. Do not spray or try to spray around the box or the perspective window;

3.After each use, the power should be cut off immediately, and the dust particles in the dust collecting drawer and filter room should be cleaned in time;

4.The dust box should not be used for a short time,and should be placed in a cool, well-ventilated place,away from heat source, non-corrosive and inaccessible to children;

5. This dust box is a precision equipment. Professionals should regularly check whether the circuit of the box is aging or falling off. Once it fails to work, it needs to be inspected and repared by professionals.
