1. How close should my fume extractor's hood be to the welding arc?
Welding fume extraction hoods should be placed close enough to the welding arc to be effective, yet not so close as to distrub shielding gases perform its function.

2. How do I dispose of used filters?
Used filters can be easily removed from the extractors. We recommend the operator wearing gloves and protective eyewear, placing the removed filters into a trashbag;
But before this, please make sure that the filter cartridge can still be used after cleaning and drying, because we manufacture the filter cartridge with the material that can be used again and again.

3. How do I know which extractor to choose?
There are several factors that determine the best extractor to use, including location, usage, materials, and quantity of smoke/fume produced. In general, however, this fume extractor is mainly used to remove smoke, not suitable for a large amount of dust working conditions.

4. How do I know which filters to use in my extractor?
We makes a wide variety of filters available that work in combination to provide the best possible filtration for your work application. Generally speaking, 95% smoke and fume suitable for use with cartridges style filter.

5. How long do filters last?
There is no clear answer to this question as too many factors can influence the life of filters, including, but not limited to, welding process.

6. If I were to exhaust welding fumes outdoors through a wall mounted arm and blower, can I retrofit the components to a filtration system should this method become prohibited?
Yes, the stationary system is designed to accommodate such a change in regulations, so you can purchase.

7. What do the different filter ratings mean?
Filters are rated on their efficiency to stop and trap particulate of a particular size. Most filters used in our fume extractors base on the particle size of their filtered dusty smoke.

8. Why should I use a fume extractor instead of an ambient (overhead) air cleaner?
Ambient air cleaners are effective supplements to fume extractors, but should be avoided as a primary tool for fume control. Due to its filtering properties and relatively high usage costs.

9. Why should I use a fume extractor instead of placing fans in my shop to blow the fumes away from my welders?
The practice of using fans and blowers in this manner is called the dilution method, and while it is commonly used, this method may not effectively remove toxic particles from the air and cannot avoid being inhaled by workers.

10. What certifications does this weld smoke collector have?
This weld smoke collector is BAV, and ISO certified, for motor we got CE certification, for other electrical parts, we could adopt Schneider brand.

11. What's the Filtration efficiency and filtration accuracy of the filter?
Nanoscale material, enable above 90% high efficiency filtration, can filter minimum 0.3μm dusts.

12. Which type of welding accept this machine?
The welding fume extraction equipment we produce is suitable for arc welding, CO2 protection welding, MAG protection welding, special welding and other places of cutting and grinding, where need to give collection and clean to smoke and dust.

13. How can we know when we have to change the filter? This machine have a sign?
Generally speaking, the filter cartridge can be used repeatedly and does not need to be replaced until it is damaged. The advantage of our filter is it can provide you much longer service time than others. The super good filter can be used for 24 month by using top grade material, and screen outside of the filter can give effective protection to sparks and the impact of large particles of dust.

For regular model:
When welding fumes cannot be sucked in effectively, or be sucked incompletely, the suction power becomes smaller (just like a vacuum cleaner used at home, which can't suck dust quickly), it means that too much dirt has been attached to the filter cartridge, the resistance for smoke passing through the filter becomes larger, and the filter is too dirty. At this time, the filter cartridge needs to be cleaned. Generally saying, in order to make sure the machine runs in good state, it's suggested to clean the filter after every 4 hours' working.

For advance model:
Equipped with Pressure difference gage, if the value pointer is less than 1, means too much air suction pressure, need to activate pulse jet cleaning forcibly, by this function, to give dual monitoring for automatic cleaning.

14. What is the minimum order quantity for this weld fume extraction unit?
The minimum order quantity for this weld smoke collector is 1 set.
