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 ofcials about restrictions and installation
inspection in your area.
1.2 Features
The BEFx is a highly efcient 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-efcient, 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™.
