Air Pollution Control Device
The working principle of a uni air filter mainly includes the following steps:
- Air Inlet
Dust-laden gas enters the dust collector through the inlet.
- Filtration
The gas passes through a filter (like bags or cartridges). And the filter captures particles on the surface or within the filter. Then the filtration process can involve mechanisms such as inertial collision, sedimentation, and electrostatic attraction.
- Dust Cleaning
When dust accumulates on the filter material to a certain extent, it can affect the dust removal efficiency. At this point, a dust cleaning device removes the dust. This restores the filtering capacity of the material.
- Discharge of Purified Gas
The filtered clean gas is discharged through the outlet, achieving the purpose of air purification.
- Dust Collection
The removed dust is collected in a hopper, which is regularly cleaned or disposed of.
Darko uni air filter design concept
“Nano” coated FEMES filter bag
Darko Environmental’s special nano-coated filter bag outperforms ordinary ones. It has a higher filtration accuracy and can resist temperatures up to 240°C. Its performance is 20% better, and its corrosion resistance is 30% better. This saves you consumables, cuts costs, and extends its life. It also cleans more thoroughly.
0.5μm filtration accuracy
The filtration accuracy of 0.5μm smoke particles reaches more than 99%.
Pulse cleaning
Fully automatic pulse cleaning provides high-quality cleaning effect and increases the life of the filter material.
ASCO pulse valve
The spray life is more than 2 million times, the failure rate is low, and the later use cost is reduced.
