How do I size my Fantech bathroom exhaust
system?
HVI, the
Home Ventilating Institute recommends that the
fan be sized for 8 air changes per hour:
| A. |
Calculate
the volume of the bathroom in cubic feet. |
| B. |
Multiply
the volume by 8 to get ventilation rate
in cubic feet per hour. |
| C. |
Divide by
60 to get volume in air ventilation rate
per minute in cfm. |
| D. |
Look in
the Performance Data under 0.4" of
back pressure for most installations to
pick a fan with the required power. |
How
do I ensure that my Fantech system will be as
quiet as you claim it can be?
| A. |
Use
insulated flexible duct. It has excellent
noise canceling properties and minimizes
condensation. |
| B. |
Install
the fan as far away from the exhaust
grille as possible. Fantech recommends a
minimum of 8' of flexible duct between
the fan and any exhaust grille. |
| C. |
Install
multiple exhaust points when large
volumes of air is to be exhausted. When
more than 150 cfm is exhausted through
one HG 6 exhaust grille noise may be
generated in the grille. Install multiple
grilles close to the sources of moisture
in order to minimize noise and get the
most effective ventilation. |
| D. |
If rigid
duct has to be used: Install a LD sound
attenuator next to the inlet of the fan. |
How
many bathrooms can I vent with 1 (one) fan?
Fantech
generally recommends that no more than 3
bathrooms are 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 2 larger,
bathrooms together.
Am
I able to paint Fantech Grills?
| A. |
All
Fantech plastic grilles can be painted. |
| B. |
A paint
that is suitable for plastic should be
used. Example: "Krylon Fusion for
Plastic" |
| C. |
If desired
paint to be used is not suitable for
plastic, a coat of primer suitable for
plastic should be applied first. Example:
"Rust-oleum Plastic Primer" |
| D. |
Warning!
If paints not suitable for plastic are
applied directly to plastic grilles it is
likely satisfactory results will not be
achieved. |
| E. |
Grille
should be removed from installation for
painting. This will prevent paint from
being applied to lamp socket contacts,
damper flap, or label. |
| F. |
For
further instruction of the painting
process follow directions of the paint
manufacturer. |
