IMH Industrial Material Handler
Cook industrial material handler provides for continuous movement of material-laden air. It is well suited for installations involving
exhaust, material conveying, polution control, air circulation and a variety of other uses. Type IMH fans are available in standard arrangements 1, 4, 8, 9, and 10 and in special designs by consultation with the factory. Standard duty construction allows for operation up to
12,000 FPM tip speed. Heavy duty designs include tip speeds to 20,000 FPM. Type IMH is available with a full range of accessories
allowing it to be adapted to many different applications.
All sizes and arrangements can be field rotated to any of the standard
discharge positions. In addition, models MH and MHR can be reversed
in the field to obtain clockwise or counter-clockwise rotation. Models
MHA and MHB cannot be reversed.
All units have continuously welded housings for leak-free operation.
All sizes are provided with lifting lugs for ease of handling.
The bearing pedestal is securely bolted to the scroll to allow field rotation
and reversing if required.
Standard bearings are grease lubricated and self-aligning ball or spherical roller type selected for a minimum of 200,000 hours average life.
Standard shafting is minimum AISI-C-1045 turned, ground and polished
steel sized for critical speed or at least 125 percent of cataloged maximum speed.
All sizes are dynamically balanced as a complete unit prior to shipment
to assure vibration-free operation. IMH fans are balanced to exceed
AMCA 204-96 recommendations for industrial process.
Accurate performance is assured through compliance with AMCA Certified Ratings Program. The MH and MHB are licensed to bear the AMCA
Seal for Air Performance. The MHA is licensed to bear the AMCA Seal
for Air and Sound Performance.

Information
Rotation and Discharge
IMH
Drive Arrangements
The direction of rotation is determined from the drive side of the fan. On single inlet
fans, drive side is always considered as the side opposite the fan inlet. The angle of the
discharge is based on the horizontal axis of the fan and is designated in degrees
above or below the standard reference axis.

Wheel Designs
MH - Open Type
The MH wheel is used for light material conveying applications when the airstreams
contain small granular material, heavy or
tacky dust, or small abrasive particulate matter. It is available in standard and heavy duty
designs.
MHB - Backplated Type
The MHB is used for conveying long, stringy,
or fibrous materials. This impeller construction
will not allow paper shreddings, threads, etc.
to wrap around the hub and blades. Available
in standard and heavy duty designs.
MHR - Reinforced OpenType
The MHR wheel is used for heavier material
conveying applications when larger/heavier
particles are to be conveyed (similar to MH with
heavier material and reinforcing rims for additional strength). Available in standard and
heavy duty designs.
MHA - Air Handling Type
The MHA wheel is used for clean air, fumes, high
temperature or light dust applications.This
design delivers higher efficiencies and lower
operating costs than radial bladed wheels due to
its flat backward inlclined blades. Continuously
welded, heavy guage construction provides a
long service life over a broad operating range.

Notes On Material Conveying
1. For applications where material is conveyed throught the fan, the actual air mixture density must be taken into account for SP and BHP calculations. The actual mixture density
can be calculated as follows.
SPSTD = SPOPER (0.075 / PM)
2. In order to properly select from the catalog tables, the operating SP must be converted to
SP at standard air conditions.
3. The resulting BHP from the selection tables must then be corrected to operating conditions.
HPOPER = HPSTD (PM / 0.075)

Unless otherwise noted wheel construction for standard duty and heavy duty is the same. *Standard duty, **Heavy duty
Motor Selection
For proper motor selection, consideration must be given to starting torque requirements along with the operating BHP. The table Maximum RPM, Wheel Weight and WK2 (above) lists the WK2 factor for different wheel sizes and types. In some cases it may be necessary
to provide a larger horsepower motor, even though it may not be indicated by operating BHP, in order to bring the fan to speed. The following formula can be applied to determine the required motor starting torque.
WK2m = WK2f (FRPM/MRPM)2 (1.1)
2
WK m - The moment of inertia required at the motor shaft, LB-Ft2
WK2f - The moment of inertia of the fan, LB-Ft2
FRPM - Fan RPM
MRPM - Motor RPM
Motor starting torque can vary greatly among motor manufacturers. The available WK2m of the motor should be obtained from the motor
manufacturer.

Accessories
Flanged Inlet or Outlet
Dampers
Flanged inlet or outlet connections allow for flange type duct
attachment. Flanged inlet or outlet connections allow the fan to be
removed without disturbing the
surrounding ductwork. Flanges
are factory mounted.
Bolted or Hinged Access Door
Dampers are available in gravity
operation and motorized control.
Motorized control dampers also
are available for in-duct installation. Galvanized or aluminum
construction is available. Dampers are shipped loose for field
installation. Motorized control
damper shown.
Shaft Cooler
A shaft cooler is required for air temperature
above 300oF. The shaft cooler is an aluminum
casting with radial vanes mounted on the shaft
between the inboard bearing and the fan
housing. It is designed to dissipate heat which
is conducted along the shaft. In addition, it
prevents excessive bearing temperatures.
Bolted or hinged access doors provide unrestricted access to the wheel for ease of maintenance and cleaning without removing the fan
from the surrounding ductwork.
Belt Guard, Arrangement 9 & 10
Factory installed belt guards cover drive components on all sides, and are split for quick access. Expanded metal construction is also
available upon request.
Isolation Base, Arrangement 1
The isolation base, arrangement 1, is used to provide a single integral support for the fan and motor in cases where the motor is not an
integral part of the fan. Isolation bases are designed to run the full length of the supported equipment and motor. The base is constructed
of structural steel channel (ASTM-A36) sized to resist belt pull and maintain proper alignment between the fan and the motor. All connections are fully welded. The isolation base requires an adjustable motor slide base for motor mounting. Isolation bases are provided with
mounting holes at each of the four corners and are available with optional rubber-in-shear, spring floor, or housed springfloor isolators
(set of four required). Optional height saving brackets are also available.
Isolation Rails, Arrangement 9 & 10
Isolation rails are required for isolating any arrangement 9 & 10 IMH fan sizes 170 and above, unless the fan is supplied with an isolation
or inertia base. Smaller fans may benefit from isolation rails if fan attachment points do not coincide with desired mounting locations. Isolation rails, supplied in pairs, are designed to run the full length of the supported equipment and can only be used on fans where the
motor is an integral part of the fan. Each rail is constructed of rigid structural steel components coated with the standard factory finish,
and are intended to be used in conjunction with two RIS Floor, Spring Floor, or Restrained Spring isolators depending on the needs of the
application. They can also be used in ceiling mount applications with RIS Ceiling or Spring Ceiling Isolators. Isolators are not included
with the rails unless otherwise specified. Optional seismic type isolators are also available; consult factory for more information.
