The VANEMASTER
™
impeller consists of two assembled hub discs with cavities to house the blades at preset
.
Acme Axial Flow Fans
™
The VANEMASTER
fans are compact, rugged, and precisely
constructed for your airflow-pressure conditions with adjustable
pitch blades (at rest).
VANEMASTER
™
fans are suited for a large number of air
handling applications in commercial, industrial and process
ventilation.
Distinguishing features of the VANEMASTER
™
fans are space
savings, ease of installation and high reliability.
angles. The blades of the rotor can be factory set to any angle between 25° and 60°, dependent on size and
speed. The rotor is provided with a hub boss for mounting onto the motor shaft.
Aluminum Blades: Special Operating

(-20 to 40°C) for standard fans.
• Maximum Temperature Range of the fan is
-40 to 302°F (-40 to 150°C) with special
motors and/or reduced speeds.

MOTOR/BLADE ASSEMBLY
Adjustment Of Blade Angles
The blade pitch may be manually adjusted to obtain different performances. The rotor must be aligned and
balanced before starting. Care must be taken to not exceed the motor output power.

fan line comprises 14 sizes with impeller diameters ranging from 10 to 63 inches (254mm to
The mounting for the rotor serves as a downstream guide vane arrangement ensuring extremely high fan
efficiency.
The motor is flange-mounted and is provided with extended leads through the fan casing to a terminal box for
electrical connection.
Variable Frequency Controls
™
When designing ventilation and air conditioning systems, the VANEMASTER
fans with frequency convertors are
an excellent alternative to centrifugal fans with inlet vane controls for systems requiring varying air quantity
requirements.
Acme Engineering & Manufacturing Corporation certifies that the
models shown herein are licensed to bear the AMCA seal. The ratings
shown are based on tests and procedures performed in accordance
with AMCA Publication 211 and AMCA Publication 311 and comply
with the requirements of the AMCA Certified Ratings Program.
The sound ratings shown are loudness values in fan sones at 5 feet
(1.524 m) in a spherical free field calculated per AMCA Standard 301.
Values are shown are for Installation Type A: Free Inlet spherical
sone levels.
Model AVD is Listed for (UL/C-UL 705)

DESIGN FEATURES
Investment, operating costs, and space requirements are lower for VANEMASTER™fans used in combination
with frequency converters that make even small installations economical.
The simple construction of VANEMASTER
™
fans provides a stable structure which minimizes vibration. Normally
there is only one or more vibration modes in which the associated speed(s) must be avoided. This is easily
accomplished by programming the variable frequency control.
As may be seen in the table, frequency control permits speeds and capacities in excess of the standard motor
rating. Care must be taken to not exceed the available motor output power or the maximum rotor speed.
Contrary to fixed speed fans, the use of speed regulation improves sound as lower speeds result in lower sound
power levels.

TYPICAL SPECIFICATIONS
Vane Axial fans shall be Direct Driven, Arrangement 4, with the motor located downstream from the impeller.
Impeller blades are to be made of a high strength, corrosion resistant, aluminum alloy. Blades are to be die cast
for maximum efficiency and low noise levels. The impeller hubs are to be die-formed of galvanized steel with
angle location marks to allow accurate blade setting at the factory or in the field.
The impeller shall be positively secured to the motor shaft. The impeller is to be statically and dynamically
balanced.
Fan housings shall be constructed of heavy gauge steel with integral prepunched flanges for leak-free
performance. High efficiency, straightening vanes of heavy gauge steel are to be installed to eliminate air swirl
and regain static pressure. The vanes are to be designed to support the motor and welded to the housings in a
manner designed to reduce air turbulence. Fans to be supplied with limited two year warranty.
Vane Axial fans shall be model AVD as manufactured by Acme Engineering & Manufacturing Corporation of
Muskogee, Oklahoma. Sizes and performance as shown on the plans.

TYPICAL INSTALLATION
INLET DUCT ELBOWS
Non-uniform flow into a fan inlet is the most common cause of deficient fan performance. An elbow located at, or
in close proximity to the fan inlet will not allow the air to enter the impeller uniformly. The result is less than
catalogued air performance. It is strongly advised that inlet elbows be installed a minimum of three (3) diameters
away from any axial or centrifugal fan inlet.
It is strongly advised that inlet elbows be installed a minimum of three (3) diameters away from any axial
or centrifugal fan inlet.
OUTLET DUCT ELBOWS
Values for pressure losses through elbows, which are published in handbooks and textbooks, are based upon a
uniform velocity profile approaching the elbow. Any non-uniformity in the velocity profile ahead of the elbow will
result in a pressure loss greater than the published value.
The velocity profile at the outlet of a fan is not uniform and an elbow located at or near the fan outlet will,
therefore, develop a pressure loss greater than its “handbook” value.
The amount of this increased loss will depend upon the location and orientation of the elbow relative to the fan
outlet. In some cases the effect of the elbow will be to further distort the outlet velocity profile of the fan. This will
increase the losses and may result in such uneven flow in the duct that branch takeoffs near the elbow will not
deliver their designed air flow.
Wherever possible a length of straight duct should be installed at the fan outlet to permit diffusion and
development of a uniform flow profile before an elbow is inserted in the duct. If an elbow must be located near the
fan outlet then it should have a minimum radius to duct diameter ratio of 1.5.
