Two Baths… One Solution!Think bathroom exhaust fans haveto be loud to be effective?

Think again.Do bathroom fans have to sound like a wind tunnel to get the job

done? The truth is, noisy bathroom exhaust fans loose much of their

effectiveness, simply because people don’t want to use them. So, odor,

moisture, mold and mildew build up. Even the most elegant bathrooms

become unattractive, and may suffer long-term damage.

Fantech bathroom exhaust fans are designed to operate quietly and ef-

fectively, so people actually use them. Yet their affordability means they’re

right for every bathroom—from simple to luxurious.

Requested by clients.Specified by designers.You’ll find Fantech bathroom exhaust fans specified on the blueprints

Why? Simple. They’re quiet, efficient and reliable, and they’re easy to

install. Better still, Fantech offers a choice of interior and exterior mounted

fans. So there’s a Fantech bathroom exhaust fan for every situation.

Please note: The Home Ventilation Institute (HVI) doesnot currently have a sound test standard for remotemounted fans. Fantech fans are considered remotemounted fans because they are not mounted within theliving area. As a result, Fantech is unable to list sonelevels for our products. In most cases, a remote fan willbe quieter than one mounted within the living area.

VENTILATION SOLUTIONS:How do you vent overlength dryer duct runs andincrease dryer efficiency and performance?

With a Fantech Dryer Booster.

Fully

Automatic

Fan Mounted

Pressure

Switch


The Dryer Facts:When it comes to dryers, where is the perfect installation with little to noduct length? The reality which contractors and homeowners have towork with is far from perfect. A short dryer duct length is not alwayspossible. This is where Fantech Dryer Boosters can help.

Under prime conditions, residential and commercial clothes dryersshould dry clothing in a timely fashion. Problems occur when dryersare connected to long runs of duct work. This is the reason why mostresidential dryers are located against outside walls. The exhausted airis vented directly to the outside without complicated ducting to hinderthe performance of the dryer.

Many dryer installations do not allow direct venting and the typical resi-dential dryer cannot operate efficiently against the resistance createdby the necessary duct work. The results are longer drying times, higherenergy usage and costs, and excessive wear and tear on the dryer.

Some common examples are:• Basements that do not allow direct venting.

• Central interior located residential laundry rooms.

• Apartment complexes with centrally locatedlaundering areas.

• Apartment complexes with individual hook-upsfor dryers in each apartment.

TYPICAL FAN PROBLEMS:Conventional types of booster fans present the following.

• Their blades clog with lint

• The blower cannot handle the long runs of ductany better than the blower in the dryer

• The motor cannot handle the heated air fromthe dryer and tends to overload

• How to turn the booster fan on with the dryer

When to boost a dryer.Typical residential dryers are rated at 160cfm. However, boosting is generally needed in order to maintain a minimum

airflow of 100cfm as duct length increases and bends are introduced in the duct line.

Based on surveying the recommendations from dryer manufacturers, and local building codes in selected areas, dryer

boosting is typically required when the duct length exceeds the following:

Maximum duct No bends 1 bend 2 bends 3 bendslength with:25’ 20’ 15’ 10’

Fantech models DBF 110, DBF 4XL and RVF 4XL are all suitable for most dryer boosting applications. Generally the

models listed can be used for maximum duct length of 60 linear feet with a maximum of six elbows using four inch rigid

duct. For longer duct runs please contact our technical department for specific recommendations

FANTECH SOLUTIONS:

A Word on Installation…

Easy!The secret is in the fully automatic pressure switch.

Whether you are installing our new inline Dryer

Booster fan, DBF 110 and DBF 4XL (complete with

switch) or the RVF 4XL (with separate switch) it is a

breeze. Designed to attach inline near the booster

fan the switch monitors dryer operation and will

activate the fan when the dryer comes on. Preset

to cycle in ten minute intervals the fan will stay on

until the dryer stops. All Fantech dryer booster fans

are suitable for rigid duct runs of up to 60 linear

feet with a maximum of six elbows. In all installations

there needs to be at least 15 linear feet of duct

between the booster fan and the dryer. In addition,

Fantech offers peace of mind with a Five Year

Warranty on all the fans featured.

Residential and CommercialFantech RVF 4XL Exterior Mounted Fan

The RVF Series exterior mounted fans addresses every situation.

The perfect solution for condominiums and apartment complexes

where concrete firewalls separate the individual units. Venting of inte-

rior dryers can now be accomplished easily with minimal interior dis-

turbance. The unit mounts neatly on the outside wall. The RVF matches

the same performance requirements as our inline fans. The enamel

finish on the RVF is as enduring as it is attractive. The energy savings

of the efficient drying of clothes when combined with our new DB10

pressure switch (mounts near fan) is a winning combination.

cations. The fans can handle lengths of duct up to 60 feet and six

fan. The attached fully automatic pressure switch is mindful of your en-

ergy use, turning the fan off and on, in ten minute cycles, only while the

dryer is running.

Fantech Fan Sizing Guidelines

Bathroom Ventilation RatesThese are only recommendations, always check local codes first.

Bathrooms under 100 square feetFor a bathroom size under 100 sq. ft. the standard rule of thumbis one (1) cfm per square foot of bathroom

Example #1

Bathroom Ventilation Sound LevelsRemote mounted fans have the potential to be extremelyquiet provided they are mounted properly.

We recommend the following:

• Use of insulated flexible duct for the exhaust system.

• Placing at least 8 feet of duct between intake grill and fan.(insulated flexible duct allows sound from fan to dissapategradually so that it can not be heard in the bathroom.)

• If applicable use multiple intake points.

• Use low sound generation grills (such as the ones supplied inour bath ventilation kits).

Kitchen Ventilation RatesBefore selecting your kitchen ventilation fan check with localresidential codes. This will typically give you a minimum ventilationrate. Additionally, check the range manufacturer’s recommenda-tions for ventilation. If range manufacturer’s recommendations arenot available use these figures in calculating fan size.

Wall Mount Hood:• 100 cfm per foot of width

Example #3

Kitchen Ventilation Sound Levels:

Fantech inline fans tend to be very quiet for range hood installa-tion, however to optimize this, please consider the followingsuggestions.

• Install a duct silencer. This will act like a muffler to preventsound generated by the fan from coming down the ductto the range.

• Install a speed controller. Often a smaller amount ofventilation will be sufficient, and by running the fan slowerit is possible to reduce the sound.

Island Mount Hood:• 150 cfm per foot of width

Example #5

Range Hood Dimensions

36″ wide by 18″ deep

Conversion#1

36″ = 3′

Calculation #1

3′ x 100 cfm per foot = 300 cfm

Range Hood Dimensions

36″ wide by 24″ deep

Conversion#1

36″ = 3′

Calculation #1

3′ x 150 cfm per foot = 450 cfm

(Note: ft2 = square feet)

8′ x 10′ bath with one toilet and one shower/tub

Calculation #1

8′ x 10′ = 80 square feet

Calculation #2

80 ft2 x 1 cfm/ft2 = 80 cfm

Bathrooms over 100 square feetIn bathrooms over 100 sq. ft. the cfm is calculated based on thefixtures in the bath. Toilets, showers, standard tubs and steamshowers† are allowed 50cfm for each fixture. Hot tubs arecalculated at 100cfm.

Example #2

11′ x 14′ bath with his & her toilets and a shower

Calculation #1


Calculation #2

50 cfm (his toilet) + 50 cfm (her toilet) + 50 cfm (shower) = 150 cfm

18′ x 22′ bath with his & her toilets, shower, and hot tub

Calculation #1


Calculation #2

50 cfm (his toilet) +50 cfm (her toilet) +

50 cfm ((shower) + 100 cfm (hot tub) = 250 cfm

†Note: We recommend that steam showers be vented using aseparate fan on a timer so that fan may be shut off duringshower use and then run afterward to dry the shower stall.

Bathroom Vent LocationsLocate the vent intake as close to the bath fixtures (toilets,showers, and hot tubs) as possible. Try to keep the vent as farfrom doors, operable windows and air supply registers as possible.The intent is to make the air flow across the room and removemoist, humid air from the appliance location. Remote fans allowthe use of multiple intakes with a single fan so that systems maybe more closely tailored to the individual room.

Fantech External Rotor Motor

All Fantech fans, with the exception of the TurboFlo Series, are powered by an external rotor motorized impeller. Like every electric

motor our external rotor motor consists of a stator wound with copper wire and a rotor. The difference is that the rotor rotates

externally around the stator.

Mechanical AdvantagesThe complete fan unit, i.e. the small external rotor motor equipped with an impeller requires minimum space. The motor/impeller combination

is matched by the motor manufacturer for optimum performance. The unique integration of both rotating parts – the motor and the impeller

– permits precision balancing in two planes to DIN ISO 1940. Rather than cantilevering off a shaft, the impeller is centered over the bearings

in the motor, thereby reducing the load on the bearings. Both the motor and the impeller are directly in the air stream and are thus very

efficiently cooled resulting in minimum thermal stress on the bearings. The above design features significantly extends lift expectancy. The

bearings are lubricated for life and require no maintenance. Fantech offers a 3 or 5 year warranty covering the complete unit on all external

rotor motor powered fans.

Speed ControllabilityFantech’s external rotor motor powered fans are 100% speed controllable. The fan output can be adjusted with solid state speed controls,

transformers or variable frequency drives. The speed controllability of the Fantech fans is achieved through careful design: The rotor in the

air stream gives superior cooling, increasing the service factor. Most motors loose too much torque as the voltage is reduced, causing the

motors to stall or operation to be unstable if the voltage is reduced too far. As the voltage is reduced the motor rpm is not reduced much at

first but when voltage is reduced farther the fan will suddenly stop. The external rotor motors in the Fantech fans are designed for increased

torque at reduced rpm’s. There is enough torque available for the motor to turn the wheel and operate in a stable fashion even at very low

rpm’s. The backward curved impeller design in the Fantech fans have no unstable areas of operation at any point of operation or at any

voltage/rpm.

Motor ProtectionEquipping motors with current sensing overload protection is not sufficient for speed controlled motors. Fantech’s external rotor motors

are equipped with internal thermal protection. The thermal protection will automatically shut down the motor if the motor is overheating for

any reason. On single phase fans this protection is totally internal. On three phase fans the thermal contacts shall be wired to an external

contactor, in order to stop the motor if an overheating condition is encountered.

Suitability:Fantech external rotor motors are classified as enclosed and are suitable for continuous duty. Fantech does currently not offer any explosion

proof external rotor motors. Since the motors are in the air stream the maximum airstream temperature is typically limited to 140° F. The

motors are not corrosion proof, but very well protected against humidity, especially when running continuously.
