CONSTRUCTION FEATURES

For those air moving applications demanding unusualruggedness and stable performance at higher static pressures.

FRAMEAll welded construction. Deep rolled streamlined orifice for most efficient performance. Panel section of 42" thru 72" sizesreinforced with angle frame. Heavy wall steel tubing for greatest structural strength. Designed to operate in any position.

HEAVY-DUTY ALUMINUM PROPELLERCircular-arc blades provide higher air flow capacity andsmoother operation. Blades heavily reinforced. Propellerprecision balanced on corrosion resistant coated shaft. Steelpropeller available as option.

BEARINGSSelf-aligning unitary pillow-blockball bearings sized for highoverload capacity and longtrouble free operation.Pre-lubricated and double sealed requiring a minimum amount ofmaintenance.

MOTORContinuous duty type, shielded ball bearings. Mounted on railsfor convenient belt adjustment. K fans should operate at 104º�F (40º�C) or less ambient temperature.

DRIVEAll fans furnished with heavy-duty static frequency oil and heatresistant V belts. Drives are 1 or 2 belt combinations depending on horsepower. Sheaves constructed of cast iron.

STANDARD FINISHAn acrylic epoxy is standard on the frame and orifice of all Kfans and is optional on the aluminum propeller. It is amulti-purpose finish that provides resistance to many chemicalsand corrosive agents. Metal surfaces are prepared prior topainting by an icon phosphate process (size 72 has a vinylwash primer) for rust protection and bonding of the paint to thebase metal.

ACRYLIC EPOXY COATINGAcrylic Epoxy finish is the standard finish for all K fans. Metalsurfaces are prepared prior to painting by an iron phosphateprocess (72" has a vinyl wash primer).

All fans factory tested and shipped fully assembled.

WARNING! DO NOT use in HAZARDOUSENVIRONMENTS where fan’s electrical system couldprovide ignition to combustible or flammable materials,unless unit is specifically built for hazardous environments.

TABLE OF CONTENTS

LICENSED RATINGS FOR SOUND AND AIRAcme Engineering & Manufacturing Corp. certifiesthat the PROPMASTER®� fans shown herein arelicensed to bear the AMCA seal. The ratings shownare based on tests and procedures performed inaccordance with AMCA Publication 211 and AMCAPublication 311 and comply with the requirements of the AMCA Certified Ratings Program.

Most PROPMASTER� fans are listed by the CanadianStandards Association Testing Laboratory asapproved.


HEAVY DUTY WALL SHUTTERS

EXCEPTIONALLY QUIET Nylon bearings practicallyeliminate the rattle prevalent in ordinary shutters.

CONSTRUCTION Rigid corrosion resistant galvanizedsteel frame, double tie rods. Industrial weight aluminum blades reinforced with steel rods. Splash proof weather seal integral with frame. Counterbalanced blades openeasier, permit higher fan capacity. Each blade has aformed reinforcement member providing triple strengthand rigidity.

NYLON BEARINGS Utilizes rust resistant stainlesssteel hinge pins to insure easy positive blade action.Corrosion resistant, helps prevent shutter sticking.Suitable for dusty or humid applications. Tough, wearresistant, more years of trouble free operation.

OPTIONAL ACCESSORIES

SAFETY GUARDS

Extruded aluminum framed guards model BA for back (motor side)and model FA for front of fan. Constructed of ½" x 1" mesh heavygauge welded galvanized wire. Open on all sides for maximum airflow. Guards are shipped knocked down. Easily assembled withconnecting clips. Bolts to fan frame. Easily removed for servicing fan. Guards are optional.

CAUTION! Guards must be installed when fan is withinreach of personnel or within seven (7) feet (2.134 m) ofworking level or when deemed advisable for safety.

TYPICAL SPECIFICATIONS

Painted Finishes Aluminum and galvanized componentsremain unpainted as a standard finish, but when required, are processed through the finishing system to applydecorative or special coatings. A high turbulence oven isused to produce a baked on finish for most specialcoatings. Decorative coatings are air dried.

Special Coatings Products receiving special coatings havecomponents painted before assembly. Fasteners are notpainted.

Acrylic Epoxy This product provides a more durablesurface.

Heresite (Air Dry) A phenolic coating with greaterresistance to most organic and inorganic acids.

OPTIONAL COATINGS

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

Performance shown is for Installation Type A - Free Inlet, Free Outlet.Performance ratings do not include the effects of appurtenances in theairstream. Power rating (BHP) does not include drive losses.

The sound ratings shown are loudness values in fan sones at 5 feet (1.524m) in a hemispherical free field calculated per AMCA Standard 301.Values shown are for Installation Type A: Free Inlet fan sone levels.

♦ MAX BHP: The brake horsepower capability of a fan motor isdependent on the degree of cooling the motor receives from the moving air

stream over the motor. The motor loading beyond the motor nameplaterating on Acme built fans does not overheat the motor and is within NEMArecommended limits. It is therefore not detrimental to the motor and iseconomically desirable.

Models numbers shown are for Exhaust Fans with standard direction of airflow (motor on intake side of propeller). To order Supply with direction ofair flow reversed (motor on discharge side of propeller) add letter “R” toModel number. EXAMPLE: K-R54L. K54, 60 & 72 not available as supply type.
