Dust particles, fumes and various oxides generated during the welding, grinding and cutting are dangerous to breathe. MLWF series dust collectors not only clear the air but also improve employee efficiency, increase employee retention, help ensure a safe working environment and reduce equipment maintenance costs.
MLWF300T Mobile Fume Extractors are designed to be utilized as an engineering safety control to protect users from the occupational hazards presented with various welding applications.
This mobile fume dust collector is suitable for collection of polishing and grinding dust, welding fume and smoke, laser marking smoke and dust, laser cleaning dust, etc.

Intelligent Control System
1. Equipped with Moland independently developed intelligent control system, all function control and feedback information are displayed on the screen.
2. Important parameters are protected to prevent misoperation.
3. Optional touchable screen.
Automatic Pulse Jet Cleaning
1. Fully automatic pulse jet cleaning, each cleaning is completed in about 0.1~0.3s, and the compressed air ejected at this moment has a good cleaning effect. The air enters the filter cartridge and expands rapidly, causing an impact vibration, so that the dust falls into the dust collection bin.
Flame-retardant PTFE Coated Filter
1. Imported Japanese Toray brand flame-retardant PTFE coated polyester fiber filter element, with a filtration accuracy of 0.3 micron and a filtration efficiency of over 99.9%, it can easily achieve standard emission of purified air.
2. Vertical arrangement.
Optional Explosion-proof Device
1. Explosion-proof fans, explosion-proof solenoid valves, explosion-proof electric control boxes, anti-static filter elements, explosion vent.
2. Other explosion-proof parts as per your requirements, such as Flameless explosion vent, one-way explosion-proof valve, etc.
Dust Collection Drawer
1. There is a large-capacity dust collection drawer at the bottom, and the pressure rod self-locking design helps you easily dispose of the collected dust.
2. There is an anti-back-suction device above the dust collection drawer to prevent the dust in the drawer from being sucked back into the filter cartridge chamber under the action of pulse airflow.
Movable and Simple
1. The integrated structure has beautiful appearance and small footprint.
2. The bottom is equipped with Fuma wheels for easy movement and fixation.
3. Button operation, simple and convenient.
