Frequently Asked Questions
Is the FV-0510VSB1 a complete fan?
No, this product is the motor and grille assembly only. It must be used with the FV-0510VSA1 housing to form a complete unit.
How do I select the airflow level?
Use the built-in Pick-A-Flow™ switch to manually select 50, 80, or 100 CFM, depending on your ventilation needs.
Can I use this fan in a shower enclosure?
Yes, it is UL listed for tub/shower areas when connected to a GFCI-protected branch circuit.
Is this fan energy efficient?
Yes, it is ENERGY STAR® certified and consumes as little as 4.4 watts at 0.1" w.g., achieving up to 12.8 CFM/W efficiency.
What is SmartFlow™ technology?
SmartFlow™ automatically increases the motor speed to maintain your selected CFM even if duct resistance causes static pressure buildup.
Is this unit compatible with 3” ducting?
Yes, with an optional 4" oval to 3" round duct adapter (FV-VS43R), sold separately.
What’s included in the contractor pack?
Contractor packs contain 4 fan motor and grille assemblies. Housing units are sold separately in 4-packs (FV-0510VSA1).
