Cyclones are a type of Air Pollution Control Equipment (APC) that capture and separate emissions using centripetal force. Unlike baghouses, cyclones do not have fabric or filters, but rather separate large particles from small particles using a vortex force. Cyclones are often used in woodworking shops to remove dust from the air, but cyclone technology can also be used to remove particles from gas or liquid media.
Who Needs a Permit?
Any operations that has the potential to emit 2 or more pounds per day, pursuant to Rule 201, section 122.
Woodworking operations venting a non-sanding processes (sawing, carving, drilling, routing, etc.) vented to a cyclone and / or baghouse require a permit if the exhaust flow rate is greater than or equal to 6,075 cfm³.
Woodworking operations venting a combined process to a common cyclone and/or baghouse require a permit if exhaust flow rate is greater than or equal to 3,400 cfm³.
