Welding Exhaust Hoods. These are source capture exhaust systems with a cartridge dust collector and exhaust fan located remotely ducted to slotted hoods backdraft hoods or fume extraction arms positioned at each weld station or point. PROCESSES The Modular Extraction Hood is appropriate for use with the following industrial welding and cutting processes.
The Air-Port Fume Exhaust Hood eliminates the weaknesses of standard fume extraction hoods. The combination of rigidity maneuverability and resilience makes stainless steel welding duct a consummate example of superior welding exhaust hose. Properly filtered airflow may be recirculated.
Recommended capture velocities for exterior hoods designed to control welding fumes are in the range of 100170 fpm 66.
