Bath Ventilation

What installation tips can you give me to get the most from my Fantech Premium Bath fan?

Keep the duct runs as short as practical. (under 25 feet). The inner core of Flexible Insulated Ducting should be as tight and straight as possible and sealed to the grille housing/fan/wye connector/termination with aluminum foil tape. Ensure there is a minimum of 3 duct diameters between any fitting and the inlet/outlet of the fan. For the PB270FV-2ES and PB370-2: It is better to have a short run of larger trunk line from the wye connector to the inlet of the fan and from the fan outlet to the termination point and longer runs of smaller duct from the grille/light to the wye connector.

How many bathrooms can I vent with one fan?

Fantech generally recommends that no more than 3 bathrooms be exhausted together. Whenever the fan runs, air will be exhausted from all the rooms that are connected to one system. This, in combination with the much higher cost of large fans, means that it is generally beneficial to exhaust a maximum of 3 smaller, or two larger, bathrooms together.

What is Static Pressure?

Static Pressure is a measure of resistance to airflow as a fan pushes or pulls air through a duct. It is measured in inches of water gauge, such as 0.1” w.g. to show the resistance is equal to raising a column of water 0.1” or one-tenth of an inch.

Can Fantech Premium Bath Fans with Fluorescent and Halogen grille/lights be installed over a tub or shower

Both the Fluorescent and Halogen grille/lights are UL listed for wet locations. When installed over a tub or shower they must be connected to a GFCI (Ground Fault Circuit Interrupter) – protected branch circuit.

Can I turn on my light separate from my fan?

Yes, Fantech recommends that the light be on its own switch and the fan on a timer such as the Fantech FD60EM.

Can I cover my Fantech Premium Bath Fan grille/light housing with insulation?

Should I run the fan after I have finished in the shower?

The Home Ventilating Institute (HVI) recommends running the fan for a minimum of 20 minutes after using the bathroom to completely exhaust moisture. Fantech offers a complete line of programmable and manual controls, switches and timers for your convenience. TheFD60EM solid state 10,20,30,60 minute timer or Ventech Programmable switches (VT20M/VT20A) are just two examples of optional controls you can use.

I am venting two bathrooms with one fan, how do I wire the timers?

Wiring the timers parallel as per the installation instructions will allow each timer to work independently.

Can the fan be mounted horizontally?

Yes, the orientation of the fan will not affect its operation. When running horizontal duct to the outside it is advisable to slightly slope the duct down to the outside vent (this allows condensation (if any) to naturally run out of the duct).

Can I use my Fantech Premium Bath Fan to provide continuous ventilation?

When used with the Fantech Ventech Fan Control, your PB fan will provide a cost effective way to comply with code requirements for controlled ventilation in residential applications.

Can Fantech plastic grilles be painted?

Yes, All Fantech plastic grilles can be painted. A paint that is suitable for plastic should be used. An example of such paint is “Krylon Fusion for Plastic”. If a paint that is not suitable for plastic is to be used, a primer coat of paint that is suitable for plastic should be applied first. An example of such paint is “Rust-oleum Specialty Plastic Primer”. Paints that are not suitable for plastic that are applied directly to a plastic grille are not likely to yield satisfactory results. As with all painting processes, surface preparation (proper cleaning) and following the directions of the paint manufacturer are critical to the quality of the painted grille. The grille needs to be removed from the installation for painting. This will prevent paint from being applied to the lamp socket contacts, damper flap, or labels.

What is the Warranty on Premium Bath Fans?

Fantech Premium Bath Fan Warranty is 7 years.

Can a motion sensor switch be added to a Fantech Bath Exhaust Fan?

Any motion sensor that has a 120V output will operate the Fantech fan.

How many auxiliary controls (VT20A) can be used with one Ventech Master Control (VT20M)?

Four VT20A auxiliary controls can be used with one VT20M. This allows ventilation in areas such as bathrooms, laumdry rooms, workshops, etc. The VT20A is connected to the VT20M with 2 core insulated cable.

Is there a way to replace my existing noisy bath fan with a Fantech Premium Bath fan without having to drywall the bathroom ceiling?
