FES350 Fume Extractor 350W Strong Suction 430 m³/h Air Flow Activated Carbon 4 Stage Purification for F1 Ultar, M1 Ultra Laser Engraver Machine and DTF Printer, 3D Printing(350 Watts)

Arrived quickly. Packaging was like a tank, a double thick box with fitted sections. Great customer service from Knokoo; though a 110 volt machine it had been shipped with a euro 220 cord. The 110 cord is on the way. Solid machine, well built, highly recommend both the machine and Knokoo. Filters are easy to find and relatively inexpensive, and this machine is robust enough to handle light TIG welding fumes and even occasional stainless steel (though the right respirator should always be worn).

I've had this fume extractor for nearly two years and am satisfied with its performance for extracting fumes for laser etcher. Good purchase.

This fume extractor is excellent for my purposes. I use it for laser ablation of the skin in my aesthetic business. It is very powerful at the highest setting but I rarely use it at that level. Even at low setting, it is effective in sucking in the smoke made by the laser when it’s burning the skin. The pros: it is relatively inexpensive compared to smoke evacuators used in the medical industry. It has an adjustable suction tube which requires no hands to use ( doesn’t need another person to assist in procedures). It has a wide range of suction from very low to very high. It has a remote control in addition to controls on the unit itself. Sturdy construction. Has fours wheels making it easier to move around. Cons: it has a short electrical cord ( they need to make it at least 6 feet long). There is a primary and secondary switch. The primary switch is located on the back which turns on the unit. The secondary switch is on the front which turns it on and in standby mode. There is a lining inside the filters that is made of cardboard which appears flimsy. At this price range, it should be made of sturdy plastic for longevity. Where can I buy more filters. The unit does come with 4 extra pre filters but I have to find out where to get additional filters ( probably from the company itself). All in all, I am satisfied with this product and would recommend it to anyone who needs a fume extractor to remove harmful smoke ( medical or industrial).

Using with XTools P2. Worked ok, with with slight smell for 2 weeks. When contacting Amazon to inquire of malfunction, company never replied. Machine no longer suctions and smoke is everywhere. It runs just long enough to break and miss the return window.

The media could not be loaded. This 350W KNOKOO fume extractor has a 4-layer filter system, and when I used it, the smell of the laser at work was gone. These smells used to bother me, and I was afraid they would hurt my lungs. I bought it for my health.When I first received it, I contacted them to use it correctly, and their service staff was very good at contacting me quickly. I received all the required information and guidance.

Never have owned one of these before but, this one seems to work well. I have my attached to an enclosed laser that I cut wood with - while the smell in the shop is dramatically reduced, you can still tell that wood has been cut with a laser - a slight camp fire smell. For not exhausting a hose outside (making a hole in the wall to a building I am renting), I am pleased with it's ability to greatly reduce the odor in my shop!

Generally good experience. I upgraded from smaller filters and this worked reasonably well for my laser cutting. It cost a lot less than other "laser filters" on the market and worked good enough for my needs.Notes / points of friction:-The hose keeps falling off the top which can impact usability quite a bit. This is the main reason I gave it 4 instead of 5 stars. At this price point I expect this to be better. I might hot glue it in place-It is supposed to come with a remote control? I could not find it in the box. However you can order replacements for not too much from ali express-I still smell the laser exhaust, but its much reduced and I think its typical for a unit of this size-I'm cutting a lot of material kicking up dust. This filter will loose suction power unless I occasionally shake / clean it out. This restores suction for me

got it for my 50w OMTech polar and it works great. have it in my apartment and it is in one room and I have a Dyson fan in the other room with a PPM sensor and it doesn't change at all when using the laser cutting 3mm wood so I know its working and I am only running it at 40% power so maybe overkill but at 40% power its really quite. there is no smell from the laser cutter about 5 feet away from it. now its just a matter of how long the filters last.
