After long-term testing and customer feedback, in order to have a better laser fume purification effect for SA and CT series purifiers, the filter cartridge

With higher cleaning efficiency and better customer experience, our company has upgraded the SA and CT series models in an all-round way.

For specific upgrade details, please refer to the following introduction materials:

1. The appearance and structure of the machine have been improved, and the upper and lower layers are installed, which can reduce the vibration of the whole chassis and make the whole machine

The machine runs more smoothly and reduces noise. For CT series machines, the four bases are changed to detachable, and the overall height is also reduced.

It is convenient for customers to use a general 20-foot container for transportation.

2. The control panel of the machine has been changed from the right side to the front of the machine, which is convenient for customers to operate and check the running status of the machine.

3. A layer of primary filter is added to the top air outlet to reduce the air disturbance at the air outlet and reduce the noise of the air outlet.

4. The filter cartridges were all replaced with Toray's high-efficiency polyester fiber-coated filter cartridges. The filter area and filter cartridge specifications did not change.

325X650MM. Just replace it with a filter material with better air permeability and a smoother surface. So the filter cartridges of the new and old models are the same

specifications used.

4. The PA-5000SA & CT series machines add off-line blowing function. When the machine is running, each filter cartridge can be cleaned.

To achieve uninterrupted cleaning of the filter cartridge during machine operation, reduce the probability of filter cartridge blockage, and prolong the service life of the filter cartridge. machine added

Cylinder sealing device, before cleaning the filter cartridge, the sealing cover on the cylinder will move down to seal the air outlet of the filter cartridge.

The pressure difference between the inside and outside of the sample filter cartridge is the same, and then the compressed air is used to blow it to achieve a good blowing effect.

5. Replaced the blower assembly inside the filter cartridge. Changed the previous spiral nozzle to our company's self-designed, patent-applied rotary spray

components. The cleaning efficiency is higher and the spraying is more uniform. The rotary blowing component can automatically rotate and blow inside the filter cartridge after ventilation,

Because the high-pressure injection hole is very close to the inside of the filter cartridge (2-3CM), so that the two rows of evenly arranged high-pressure injection holes can effectively remove the filter cartridge.

The smoke and dust on the surface are blown to the dust collection drawer to avoid the blockage of the filter cartridge caused by the agglomeration of the smoke and dust on the surface of the filter cartridge.

6. A pre-filtering device is added to the air inlet of the machine, so that the large particles of smoke and sparks will be blocked and dropped into the dust box, so that the

In order to reduce the smoke and dust contacting the surface of the filter cartridge, and to prevent sparks from contacting the surface of the filter cartridge to burn the film on the surface of the filter cartridge, prolong the service life of the filter cartridge.

Use life.

7. The pictures of the new machine are as follows:

The above upgrades and changes are all to better improve our product quality and customer satisfaction. We will be on June 1

Started production and sales of new purifiers. please be aware!
