Acme Engineering PL Installation Manual

CONSTRUCTION FEATURES

Model PL belt drive fan is a downblast centrifugal power roof ventilator designed for exhausting clean air. Capacities
range from 635 to 31,810 CFM and up to 1 inch static pressure. The PL is built to be quieter than conventional
exhausters. In fact, they are quieter than many conventional exhausters with sound curbs. For this reason PL
exhausters are suitable for all types of commercial and institutional buildings such as schools, hospitals, office buildings
and retail stores requiring low noise levels.

Hood

Full 360° perimeter
outlet area for efficient
performance. Hinged
to permit easy
accessibility and
servicing.

Motor

All motors are
continuous duty type
and have lubricated
shielded ball bearings.
The motor is mounted
on special slide rails
that help maintain
correct belt drive
alignment. Factory
wired to junction box.

Aluminum Construction

Heavy gauge aluminum hoods, housing and
base provide durable, weather protected
construction.

Drive Assembly

Cast iron drives sized for
150% of drive horsepower
with static free, oil and
heat resistant belts.

Frame

The entire weight of
the motor, impeller,
drive assembly and
hood is carried by a
rugged structural
frame that transmits
load directly to the roof
curb.

Disconnect Switch

Factory installed disconnect
switch is standard.

Aluminum Hollow Airfoil Impeller

All exhausters have backward curved non-overloading
aluminum impellers with the hollow airfoil blades.
Impellers are precision balanced for smooth, vibration
free operation. Hollow airfoil blades produce a
centrifugal impeller having high performance with lower
air noise, and at less horsepower.

Bearings

Permanently lubricated in a duplex split pillow block housing. Bearings are resiliently
mounted in neoprene rings and rated at L
limited warranty on duplex split pillow block bearings (unitary pillow block bearings
standard on PL368-543).

CFM and BHP vs. Static Pressure

The brake horsepower capability of an exhauster motor is dependent on the
degree of cooling the motor receives from the air moving through the motor.
The motor loading beyond the motor nameplate rating does not overheat
the motor and is in accordance with the motor manufacturer’s
recommendations. It is therefore not detrimental to the motor and is
economically desirable. Power rating (BHP) does not include drive losses.

CFM and BHP vs. Static Pressure

The brake horsepower capability of an exhauster motor is dependent on the
degree of cooling the motor receives from the air moving through the motor.
The motor loading beyond the motor nameplate rating does not overheat
the motor and is in accordance with the motor manufacturer’s
recommendations. It is therefore not detrimental to the motor and is
economically desirable. Power rating (BHP) does not include drive losses.

OPTIONAL COATINGS

Coatings

Aluminum and galvanized components remain unpainted as
a standard finish, but when required, are processed through
the finishing system to apply decorative or special coatings.
A high turbulence oven is used to produce a baked on finish
for most special coatings. Decorative coatings are not baked
on.

Decorative Coatings

Acme offers 16 popular colors for decorative finishes utilizing
an industrial grade enamel applied to the exterior of the fan.
Special colors are available upon request. See your Acme
Representative for complete color selections.

Special Coatings

Products receiving special coatings have
components painted before assembly. Fasteners are
not painted.

• Acrylic Epoxy

This product provides a more durable surface.

• Carboline Sanitile (Eisenheiss)

This air dry synthetic polyester forms a black coating
that offers greater resistance to most organic and
inorganic acids.

• Heresite (air dry)

A phenolic coating with greater resistance to most
organic and inorganic acids.

• Insulmastic

A black asphalt based mastic that provides some
condensation control, sound deadening and
corrosion resistance.

NOTE: For any coating selected the user assumes the responsibility for the corrosive agent, its concentration,
temperature, moisture content and the ultimate effect on the coating and the equipment.
