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.

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.

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.

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.

AVD VANEMASTER™fans should be specified by giving both the fan diameter and the hub diameter. A typical
fan selection example would be AVD 1000/403. Additional data concerning motor RPM, voltage, Hz and
accessories are required to create the proper fan selection for each application.

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.
