ACT™ Conversion
Airow Control Technology (ACT™)
Some local codes limit the maximum amount of CFM a range hood can move. ACT™ allows you 
to control the maximum blower CFM of select Zephyr Ventilation range hoods without the need for 
expensive make up air kits. ACT™ enables the installer to easily set the maximum blower speed to 
one of two most commonly specified CFM levels; 390 or 290 CFM. The usage of ACT™ may not be 
necessary for your installation. Please check your local codes for CFM restrictions.
