Innovative design for long life, low noise and low power consumption, the Delta Breez humidity sensor exhaust fan model VFB25ACH delivers air flow rate of 80 CFM at <0.3 Sone. Power consumption is only 8 Watts with an efficiency rating of 10 CFM/Watt. The life expectancy for this fan is 70,000 hrs, which is about 8 years running continuously. This quiet energy efficient bathroom fan combines several design innovations, including a switching power supply that converts AC 110~220V power source to DC power to drive a DC brushless motor. This design provides a quieter solution with energy savings up to 65% compared to traditional AC motor products. Users can cycle switch on/off for humidity sensor mode and full speed mode. This product has a default humidity threshold setting of 50% humidity environment. In humidity sensor mode, fan will kick in when the humidity level reaches 50% and above, and will turn off automatically after the humidity level comes back down to lower than 50%. The motor will adjust the speed according to humidity levels. When humidity level is high, the fan will spin faster to quickly exhaust the moisture. When humidity level is low (but still higher than 50%), the fan will run at a lower speed, which allows you to continue to vent for better indoor air quality. This product also incorporates a dual color (blue and amber) LED indicator to show if it is running at humidity sensor mode or full speed mode.
Because of the effects it has on health, comfort, and serviceability, indoor air quality in our homes is becoming an increasing concern to many people. The American National Standards Institute (ANSI) has recommended a mechanical exhaust system to be installed in your home to provide whole building air ventilation (ASHRAE Standard 62.2-2007) in order to improve indoor air quality. This Delta Breez VFB25ACH humidity sensor exhaust fan is an excellent product to achieve this goal with its superior features of ultra low power consumption, and almost silent operation. Cycle switch on/off in between humidity sensor mode and full speed mode for continuous or smart operation. The energy cost for operating this fan 24/7 for an entire year is less than approximately $7.62.

10 Questions from the Community
Does fan cut itself off automaticaly when the humidity comes back down to normal?
A. Yes, the Delta Electronics VFB25ACH Humidity Sensing Exhaust Fan first automatically slows down as the humidity decreases and then does turn off automatically when the humidity is back to normal. It can also be set to whisper mode to provide always-on whole house air recirculation. The estimated energy cost for doing so is around $8 per year.
