SW-CJ-1FD  Vertical air supply purification table



Product characteristics



1. Arbitrary positioning door shifting system is adopted



2. The shell is formed in one piece with color steel plate (1D,1G for 201). The working table is SUS304 brushed stainless steel, which is corrosion resistant and easy to clean



3, lighting and sterilization system safety interlock



4, digital display LCD control interface, fast, medium and slow three speed, more humanized design



5. Vertical quasi-closed mesa and the formation of air curtain in the operation room can effectively prevent the input of external gas and clean the operation area

Structural features



Purification table by the box body, fan, high efficiency filter, operation switch and other components. The box is made of color steel plate, the surface is sprayed with plastic, and the working table is made of stainless steel. 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 hePA filter can be extended effectively.



The working principle of



After passing through the primary effect filter, the air is pressed into the static pressure box by a centrifugal fan, and then filtered by a high efficiency filter, it is blown out from the air outlet surface to form a clean air flow. The clean air flows through the area to be purified at a uniform section of wind speed and takes away the dust in the area, thus forming a clean working environment.



Install and use



This workbench in position location should be in the cleaner work indoor environment (zui in hundreds of level or three hundred thousand level) between the primary purification, plugged in, according to the control panel can be shown in the function of the open, in response to purify before starting the machine workspace surface and shell are seriously cleaning, to remove surface dust, boot 10 minutes after the normal operation can be implemented.



maintenance



1. According to the actual use, remove the primary filter and clean it regularly. The cleaning cycle is generally 3-6 months. (If not cleaned for a long time, dust accumulation will affect the air intake and reduce the cleaning effect.)



2, when the normal replacement or cleaning of the primary filter air filter, still can not reach the ideal section of the wind speed, should adjust the working voltage of the fan, so as to achieve the ideal uniform wind speed.



3. Generally, when the operating voltage of the fan is adjusted to the high point of ZUI after 18 months of use, the ideal wind speed still cannot be reached, indicating that the HEPA filter has accumulated too much dust (the filter hole on the filter material has been basically blocked, it should be updated in time). The service life of the general HEPA filter is 18 months.



4. When replacing hePA filter, please pay attention to whether the model, specification and size are correct (configured by the original manufacturer), press the arrow wind direction device, and pay attention to the surrounding seal of the filter. No leakage occurs.



General faults, causes, and troubleshooting methods



The fault phenomenon



why



Discharge method



The main power switch will not close, and will trip automatically



1. The fan is jammed, causing the motor to stall or the circuit to be short-circuited



1. Adjust the position of the fan shaft, or replace the impeller and bearing to check whether the line is in good condition.



2. Check the insulation resistance of the circuit and components against the shell point by point according to the circuit diagram, and repair insulation faults.



The wind speed is low



1. Excessive dust accumulation in the primary filter.



2. Failure of hePA filter.



1. Clean the primary filter.



2. Replace the hePA filter.



Fan does not turn



1. Contactor does not work.



2. The fan power fuse has been fused.



1. Check whether the contactor circuit is normal.



2. Replace molten core.



The fluorescent lights don't work



1, lamp tube or relay damage.



2. The fuse of the lamp has been fused.



1. Replace the lamp or relay.



2. Replace molten core.
