Large air flow smoke catcher&acquirer with metal suction hood and DN200mm arm
1. Mobile intelligent welding fume extractor has two directional and two rotary polyurethane casters with
brake device for easy moving and stationing. It is suitable for the purification of fume and dust
generated in all kinds of welding, grinding and other places as well as for collecting rare metal
particles and precious material.
2. The fume comes from the processing will be sucked into the extractor through the hood, first the fume passes the 1st layer spark intercept steel mesh which will separate and intercept the spark initially.
And the fume enters into second layer namely filter preventer plate to avoid residual sparks enter into main filter layer directly through ramifying the fume. At last the fume enters the third layer namely the
main filter cartridge for ultimate purific he filtration efficiency can reach 99.9%.
3. Intelligent model using PLC automatic control makes operation easy; filter rotates with the use of full-
automatic cleaning in all directions, so that there is a more thorough cleaning filter surface, always to guarantee aconstant air volume absorption; Filter is made of imported microporous PTFE film ,
filtering with high precision can meet GB indoor emission standards.
4. Power phase sequence instructions, short-circuit protection for lack of phase, with shutdown
protection measures when too high temperature.(Optional)
5. With large air volume, low noise and better capture effect. Suction hose uses the real anti-
temperature, wear-resistant compounded materials, without crack and damage for sparks but longer
6. On the control panel, it includes:
- Power switch
- Power indicating light
- PLC implementation of filter automatically cleaning
- Fan rotation direction monitor (Inside the control box)
Separation: Dust laden fume are sucked into the extractor by the suction force induced by fan’s working, with deflector fume’s flowing speed is slowed, big practical and sparks are cooled, separated and then settle into dust collector. Fine fume and dust enter into filter compartment to be filtered by the filter
cartridge. The filter cartridge is coated with PTFE film which is covered with uniform pores, it has good air permeability, and dusts are filtered out on its surface. Purified air enters into the filter cartridge’s interior and then discharged into workshop directly or out of the workshop through pipe line.
Cleaning: When dusts accumulate continuously on filter cartridge’s surface, the pressure difference between its interior and exterior will increase steadily, when the pressure difference reach pre-set value(1500Pa), the pulse valve will open, dry, oil-free compressed air rush into the reverse blow cleaning system. The system rotate and high pressure air stream jet at the interior of filter cartridge, blow off dusts accumulated on the filter cartridge’s surface, dusts fall into dust collector under gravity, thus the whole cartridge’s surface is cleaned.
This extractor can be automatically cleaned and manually cleaned, automatically cleaning is as following:
1. When air pressure difference reach 1500Pa between the interior and exterior of the filter cartridge, the
system will implement interval rotation pulse blow cleaning.
2. When the fan stops working, the system will implement rotation pulse blow cleaning for three times.
1. CE certification and EMC test report is approvable.
2. Application for large fume occasion, the force of sucking is large.
3. Large air flow is adjustable through the air flow valve on the suction hood.
4. Automatically cleaning, maintenance easy, the machine service life is long.
5. Export many years, we are professional manufacturer in this field.
6. We will supply 24 months warranty besides quick-wear parts
