NOTE: 8' Floor-Mounted Hoods are offered with both
vertical-rising and horizontal-sliding sashes, and have
different CFM’s and pressures.
Proper blower selection can be determined from these
exhaust requirements and the total system static
pressure loss. Contact Labconco Customer Service at
800-821-5525 for assistance in sizing a blower system.
