Product Description


Automatic cleaning Welding Fume Extractor with one arms

Use for purification of the smoke and dust during the welding, polishing, cutting, grinding process and the recycling of rare metals and precious material, can purify large amounts of suspended small metallic particles in the air. 



Performance description
· Integral structure with Fuma wheel at the bottom, flexible movement and fixing
· Anti-suction device to make the effect of ash cleaning more thorough
· Power supply condition monitoring:  alarm of fault phase overvoltage and undervoltage to prevent motor and electrical   components from damage
· Pressure condition monitoring: alarm for low pressure of gas source to prevent incomplete dust cleaning.
· Pressure differential gauge shows the working state of filter element intuitively, and automatic pulse back blowing with       excessive pressure difference
· Operation temperature monitoring: alarm system temperature is too high to prevent fire
