1. GENERAL INFORMATION
1.1 introduction
These instructions provide both general guidelines and
special requirements for all parts in the BEFx Ventilator Fan
product line. Before specifying a design or beginning an
installation please carefully review these instructions. Contact
local building or re ofcials about restrictions and installation
inspection in your area.
1.2 Features
The BEFx is a highly efcient box ventilator that uses a
backward curved centrifugal impeller for the movement of air
in exhaust and air supply systems by providing high capacity
at high static pressure. It is designed to exhaust lint-laden air
from multiple Type I and Type II residential and commercial
clothes dryers, exhaust commercial hoods, or to provide
make-up air for laundry or mechanical rooms. The ventilator
cannot be used for transport of large particles. Suitable uses
include, but are not limited to: comfort ventilation, make-up
air for laundry and mechanical rooms, and exhaust and air
supply in kitchens/bathrooms in multi-story, multi-family
buildings. The BEFx box ventilator can be installed indoors
as well as outdoors and used in both intake and exhaust
applications.
The BEFx ventilator housing is made in galvanized steel,
while the impeller is welded aluminum. The design is Type
B, Spark Resistant Construction, completely insulated
against re, noise, condensation and heat with 2” berglass
insulation. A service door is provided to allow easy access
to the motor and impeller. The welded aluminum impeller
is statically and dynamically balanced with permanently
attached balancing weights. The BEFx is equipped with
an extremely energy-efcient, totally enclosed, permanent-
magnet motor of class NEMA Super Premium EISA (IE4).
IP54 Protection Class. Sealed ball bearings. The motor
is protected from overloading, blocking, over and under
voltage, and over-heating by a factory programmed EDrive
motor controller by ENERVEX for optimal operation of the
ventilator.
The BEFx Box Ventilator is a component in the MCAS
Modulating Combustion Air System™, MDVS Mechanical
Dryer Venting System™ and MBES Modulating Building
Exhaust System™.
Exhaust temperature must be above 10°F (-12°C) but should
not exceed 400°F (200°C). The ambient temperature must
be within -20°F (-30°C) and 105°F (40°C).
1.3 Components
The box ventilator comes with the components shown in Fig.
1.

3. MECHANICAL INSTALLATION
3.1 Positioning
The ventilator can be oriented in multiple positions.
Acceptable ventilator orientations are shown in Fig 3.
The BEFx can be installed indoors and outdoors without any
modications.
Wherever the ventilor is installed, make sure there is
space enough to open the access door to an angle of
approximately 90°, as shown in Fig 4, and to access the
locking screws.
Fig 3
Fig 4
CAUTION
Never operate the ventilator with open access
door

3.2 Door Position
The ventilator can be oriented in multiple positions.
Acceptable ventilator orientations are shown in Fig 3.
The BEFx can be installed indoors and outdoors without any
modications.
Wherever the ventilor is installed, make sure there is space
enough to be able to open the access door to an angle of
approximately 90°, as shown in Fig 4, and to access the
locking screws.

010.1220.0719 01.21
3.3 Floor Or Roof Mounting
To minimize transfer of noise and vibration, the ventilator
unit should be mounted on a level, stable and vibration-free
surface. If mounting on a wooden surface, a cement tile
should be placed on the oor prior to mounting as shown in
Fig 5.
Once the installation location is selected the support legs
must be installed. To facilitate support leg installation, keep
ventilator unit on pallet.
For the standard position (Fig 5), bolt holes are pre-drilled
and support legs should be aligned and secured with the
enclosed hardware.
For all other positions, the legs should be placed in proper
position using variable mounting points.
DO NOT FASTEN THE VENTILATOR TO THE BASE.
The ventilator is tted with sound dampers suited to the
requirements of the operating area.
Fig 5
Fig 6
3.4 Ceiling Mounting
If hung from the ceiling, brackets with eye hooks (not
included) must be installed as shown in Fig. 6..
Ceiling bolts must be properly sized to safely carry weight of
the ventilator unit.

010.1220.0719 01.21
3.5 Connection To Duct
The ventilator can be connected to a duct. To acheive
maximum performance with minimal energy consumption,
the ventilator should be connected to the duct system with
the specied lengths of duct before and after the ventilator.
NOTE: The distance “3 x D” is not a requirement. It is a
recommendation that will help achieve maximum performance with
minimal energy consumption
3.6 Connection To Flexible Duct
Flexible duct sections can be used to reduce vibrations in the
duct system. If used, the FLF should be connected between
the fan inlet/outlet and the main duct as shown in Fig 8.
This will decrease system vibration and prevent fan housing
deection.
NOTE: The distance “3 x D” is not a requirement. It is a
recommendation that will help achieve maximum performance with
minimal energy consumption
3.7 Outdoor Termination
The BEFx box ventilator is suitable for outdoor installations. It
can mount directly to the roof or on a roof curb as shown in
Fig. 9 and Fig. 10. When the ventilator is used at an exhaust
termination point, local codes may require a gooseneck to
be installed at the outlet, preventing rain entering into the
ventilator. See Fig. 9.
