Industrial Dust Control
metal_polishing dust collection

Many times the applications that are involved in dust collection include manufacturing processes such as deburring, sanding, chopping, cutting, polishing, agitating, stirring, and mixing.  Materials include any solid that can be broken down into small particulate such as various metals, wood, rock, plastic, and other organic material such as soil.

Fume & Smoke Extraction
welding fumes air filtration

Control of fumes can range widely from noxious odors to hazardous volatile organic compounds (VOC’s). DualDraw smoke extraction focuses on applications such as welding, plasma cutting, laser cutting, soldering, gouging, and other hot work that produces unwanted and unhealthy smoke. DualDraw downdraft tables, downdraft booths, robotic weld cell collectors, and other air filtration equipment helps address this fundamental indoor air quality issue inside manufacturing facilities. Their  patented design allows for operators to effectively perform their jobs without effecting sheild gas and ultimately the quality of welds or cuts. 

Composite Dust Collection

Composite dust collection applications include processes such as sanding, finishing, cutting, buffing, and polishing. Typical materials collected are fiberglass, carbon fiber and blended plastics. Often customer requirements will include a high-efficiency pleated air (HEPA) filter that is at a minimum 99.97% efficient to 0.3 microns in size.
