Please visit our global website for a more comprehensive look at Delta operations, products and company profile. What makes Delta Breez Ventilation fans different? 1. All Delta Breez Ventilation fans are manufactured with DC Brushless motor technology 2. All Delta Breez Ventilation fans are Energy Star certified 3. All Delta Breez Ventilation fans have soft start and lock protection functions 4. All Delta Breez Ventilation fans are engineered to run continuously for 7, hours 5. All Delta Breez Ventilation fans come with a 3 year limited warranty What is CFM and Sone? CFM and Sone are how bath fans are generally compared. CFM (Cubic Feet per Minute) is air flow the amount of air extracted per minute when the fan is running. The amount of CFM needed is generally related to the size of the area exhausted please see Sizing the right fan below. Sone level is how loud the fan is to the human ear. Doubling the sone value means double the noise. The average 8 CFM bath fan runs at.8~2.5 sones. Delta Breez fans run as low as <.3 sones. At less than.3 sones, the fan is virtually silent. This is the lowest noise rating of any exhaust fan in the market. Because energy efficiency and performance are at the core of all Delta products, Delta Breez fans produce industry leading CFM per watt ratios and sone ratings. To qualify for the Energy Star label, an 8 CFM ventilation fan must produce 1.4 CFM per watt. Delta s 8 CFM VFB25AC produces 11 CFM per watt, which is 835% than the Energy Star requirement today. Energy Star also requires a ventilation fan to be at 2. sones or less. Our BreezSignature 8 CFM fan runs at <.3 sones. Is it ok to exhaust into the attic? No. The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) recommend exhausting through the roof only. How do I determine which bath fan I need features and size? Bathroom Ventilation The following are guidelines for ventilating both large and smaller bathrooms using intermittent or continuous ventilation. Small rooms: For bathrooms up to 1 square feet in area, HVI recommends that an exhaust fan provide 1 CFM per square foot (approximately eight air changes per hour) to properly ventilate the bathroom. Example: Bathroom is 8'x5' (with 8' ceilings). Multiply 8 x 5 = 4ft. Bathroom area is 4ft. At 1 cfm per square foot the minimum recommendation is a fan rated at 4 cfm. Larger rooms: For bathrooms above 1 square feet in area, HVI recommends a ventilation rate based on the number and type of fixtures present, according to the following table: Toilet Shower Bath Tub Jetted Tub 5 CFM 5 CFM 5 CFM 1 CFM Note: Enclosed toilet rooms must have an operable window or a fan for ventilation. Example: The bathroom is 2'x12'. There is a tub (without jets), a shower enclosure and an enclosed toilet. Each fixture requires 5 cfm: Tub Shower Toilet Total 5 CFM 5 CFM 5 CFM 15 CFM Data source: How does the Humidity Sensor function operate? Humidity Sensor fans have two modes: Humidity Sensing Mode and Always On Mode. Flipping the wall switch toggles the fan back and forth between modes. LED light indicator underneath the fan grille shows the user which mode the fan is in. Blue light means the fan is in Humidity Sensing Mode. Amber light means the fan is in Always On Mode. In Always On Mode, the fan runs continuously at full speed. In Humidity Sensing Mode, the fan will only come on when the fan senses a humidity level of 6% RH (Relative Humidity) or above. The fan speed automatically adjusts according to the humidity level. The VFB25ACH humidity control fan curve is as follows. Air Flow Humidity Control 3 (CFM) (%RH) Humidity 2 21

13 On very rare occasions (about 1% of the time), our fan may still run even though the homeowner feels or detects the house humidity level is lower than 6% RH. The possible reasons are: 1. Our sensor tolerance is +/-5% RH 2. Outdoor humidity back draft to the fan 3. Indoor temperature level Manufacturer recommended actions: 1. Let the fan run since it is good to keep venting the house and the electric bill is minimal (approximately less than $1 per year) 2. Shut the fan switch when not in use Why would the humidity sensing fan keep running when my home s humidity is less that 6% RH? The Delta Breez humidity sensing fans work normally in summer months, even with the air conditioner turned on, when temperatures reach 76.9 F to 13.9 F. Due to the characteristics of the humidity sensor, in the cooler winter months when the temperatures are between 35 F 6 F, it will become more sensitive. Some customers may experience the fan continuously running even when humidity level is lower than 6% RH, this usually only happens during the winter time. Can Delta fans be installed in a side wall? Why is a DC brushless motor better than a AC motor? Does it require any special installation or wiring? DC brushless motor exhaust fans use 74% less power than AC motor exhaust fans, and DC brushless motors are a lot quieter and have longer lasting bearings with soft start function. A DC brushless motor can run continuously for 7, hours (approximately 8 years). DC brushless motor technology allows Delta Breez fans to achieve extremely low noise levels. DC brushless motor fans install just like AC motor fans. No special wiring is needed. A transformer built into the fan automatically switches the power supply from AC to DC. What is Soft Start Function? When the fan is powered on the motor will control the speed from low to high in 1 seconds unlike an AC Motor which jumpstarts the fan. This process increases the motor bearings life. What is Lock Protection Function? With this unique function the Delta Breez Ventilation fans will automatically power off when the impeller is locked abnormally. For example when a buildup of dirt and dust accumulates on the fan over its lifespan. The fan will repeatedly turn itself on every 12 seconds until the impedance is removed. Can the Breez fan motor be replaced? All Delta BreezSlim and BreezGreenBuilder series exhaust fans have project pack separate units for the housing, fan motor and grille, allowing the fan motor to be installed after the housing is installed such as in new construction. This also allows the fan motor to be replaced at any time while keeping the same housing. The precision engineering and DC brushless motor construction of Delta Breez fans makes having to replace the fan motor an unusual circumstance. Can I keep the housing of my old fan and just replace the fan motor with Breez? No. For proper performance, it is recommended that Delta Breez Ventilation Fans only be used with Delta Breez components. What is the Delta Breez Ventilation Fan Warranty? The Delta Breez Ventilation Fan Warranty is 3-Year limited warranty. Please refer to the Warranty tab of this binder. What type of light bulb(s) are used in the Fan/Light Combos? Does the packaging contain the bulb(s)? BreezSignature: The main light bulb in the VFB25ACL and VFB25ADL is a 26W CFL with GU24 base (pin style). The night-light in the VFB25ACL and VFB25ADL is a 4W incandescent light bulb with E12 screw base. Both lights are included in the box with the fan. Replacement light bulbs can also be purchased at most major home improvement retailers or through your local contractor or supplier. BreezSignatureLED: The main light and night-light in the VFB8D4LED1 are contained in one LED Light Module. The LED Light Module is installed in the grille. The LED Light module is replaceable. BreezGreenBuilder: The main light bulb in the VFB5C4L1 and VFB8C4L1 is a 26 W CFL with GU24 base (pin style). The light is included in the box with the fan.
