Innovative design for long life, low noise and low power consumption, the Delta Breez dual speed exhaust fan model VFB25AX delivers two air flow rates of 80 CFM at <0.3 Sone and 110 CFM at 1 Sone.  Power consumption is only 8 Watts with an efficiency rating of 10 CFM/Watt when operating at low speed (80 CFM) mode. The life expectancy for this fan is 70,000 hrs, which is about 8 years running continuously. This quiet energy efficient exhaust 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 low speed mode and high speed mode. This product also incorporates a dual color (green and amber) LED indicator to show if it is running at low speed mode or high 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 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 VFB25AX dual speed exhaust fan is the best product to achieve this goal with its superior features of ultra low power consumption and almost silent operation. Cycle switch on/off to change the mode in between low speed and high speed. The energy cost for operating this fan 24/7 for an entire year is approximately $7.62 to $15.51.
