Humidity Sensing- Delta VFB25ADH
design for long life, low noise and low power consumption, the Delta
Breez model VFB25AC bathroom fan has an air flow of 110 CFM and <1.0
Sone. Power consumption of 8 Watts with an efficiency rating of 10
CFM/Watt. The life expectancy for this bathroom 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 brush less motor. This design provides a quieter solution
with energy savings up to 65% compared to traditional AC motor
products. The Delta Breez bathroom fan is easy to install in new
construction or an existing bathroom to deliver an unobtrusive appliance
with aesthetically pleasing results. The product is safety certified
and has passed the EMC test.
