laser marking metal
The dust generated by laser marking metal is mainly fine metal dust. This kind of dust is easy to block the filter with the general smoke purifier on the market, and the cost of consumables is high. Aiming at this working condition, Puhua Environmental Protection has developed HSB/ HTC /HCT series fume purifier with automatic dust removal device to avoid clogging problems


Laser marking non-metal
The soot generated by laser marking non-metal is mainly micro dust and smoke. This kind of soot mainly has the characteristics of small particle size, stickiness, and peculiar smell. It is necessary to solve the problem of blockage of dust particles and the problem of peculiar smell. Some The dust in the working condition is also corrosive. For this working condition, Puhua Environmental Protection has developed the HC/HBC series of smoke purifiers with multi-stage filter devices, which can solve the above problems.



Laser welding processing
The smoke generated by laser welding is mainly high-temperature dust and smoke. This type of smoke mainly has the characteristics of small particle size, viscosity, and high temperature. Because laser welding, especially continuous welding, continues to generate high-temperature gas mixed with sparks, it is easy to Ignite the filter, creating a safety hazard. In response to this working condition, Puhua Environmental has developed a series of high-temperature-resistant, flame-retardant smoke purifiers with a pre-spark arrester to avoid burning out the filter.


Laser cutting and adsorption
When cutting flexible sheets such as FPC, pole pieces, and aluminum foil paper with low-power lasers, it is necessary to first absorb the cutting workpiece on the work surface, and then vacuum the dust while processing. This requires a host to achieve two functions. For this working condition, Puhua Environmental Protection has developed the DG series of high negative pressure and silent series industrial dust collectors, with a power of 4.0kw, which can achieve a noise lower than 72dB(A).

laser cut metal
When laser cutting metal sheet metal, a large amount of dust and smoke will be generated. If it is not treated in time, it will cause environmental pollution and damage to the laser head. Generally, direct suction, blowing suction, and damper type dust extraction are used. For different dust extraction methods, Puhua Environmental Protection has DF series industrial dust collectors with different powers to solve the problem.
