Vibration Isolation - Internal isolators support the

entire drive assembly, wheel, and scroll to provide
long life and quiet operation.

Housing - The fan cabinet is constructed of

galvanized steel for corrosion resistance and
maintenance free operation.

Access Panels - Two side panels are removable for

inspection or servicing. Removal of either side panel,
gives easy access to all the fans internal parts.

Bearings - Permanently sealed, pillow block ball

bearings are selected for a minimum L10 life in excess
of 100,000 hours (L50 average life of 500,000 hours)
at maximum catalogued operating conditions.

Duct Collars - Inlet and outlet duct collars are

provided for easy duct connections.

Motor - Ball bearing motors are carefully matched to

the fan load and receive the cooling benefits of being
in the airstream for increased motor life.

Wheel - Forward curved, centrifugal, galvanized

steel wheel is utilized to generate high efficiency
and minimal sound. Each wheel is statically and
dynamically balanced for long life and quiet operation.

Multi Discharge Positions - Where space between

duct and ceiling is a premium, bottom horizontal and
top horizontal discharge positions are available for
easy installation.

Nameplate - Permanent stamped aluminum

nameplate for model and serial identification.

Sloped Filter Boxes - The double-vee configuration

constructed of galvanized steel. Filters are available
in 1 or 2-inch pleated
disposable media or
permanent washable
aluminum mesh. Side
access panels are
standard for easy
maintenance.

Multi Discharge
Positions - BDF fans have been designed for

horizontal mounting and are standard with bottom
horizontal discharge. Optional top horizontal
discharge is also available.

Insulated Housing - For noise reduction and

condensation control, the interior of fan housing and
filter box can be lined with a fiberglass duct liner.
The duct liner can be utilized to reduce radiated
noise from fan housings. It is recommended for
applications when fans are placed in acoustically
sensitive locations. The duct liner also reduces the
noise radiation from the inlet and outlet of the fan.
The accompanying table depicts the reduction that
can be obtained in each octave band.

Coatings - A wide variety of protective or decorative

Products for in-depth information.

Typical Installations

All BDF fans have been designed to be
mounted horizontally. For ease of installation,
knockouts are provided at each location where
mounting brackets are shown. Universally
adjustable brackets are available to mount the
fan in hanging or base mounted positions.

In order to assure proper fan performance,
caution must be exercised in fan placement
and connection. Obstructions, transitions,
poorly designed elbows, etc., can cause
reduced performance, excessive noise, and
increase mechanical stress. For performance
to be as published, the system must provide
uniform and stable airflow into the fan.
