BACKWARD CURVE
BCS-Backward Curve Wheel
High efficiency backward curved wheel
has blade shape similar to the convex
shape of the BCA airfoil wheel. This shape provides nearly identical performance characteristics at a given speed at a slightly
lower efficiency. BCS wheels also exhibit the same non-overloading horsepower characteristics and stable performance
over the entire pressure curve. BCS wheels should be specified
in moist or lightly contaminated air systems. Noise levels are
lowest in the peak efficiency range of the performance curve.
Class 3 wheels utilize a circumferential blade stiffener for higher
tip speed capability.

Axial / Fixed and Adjustable
Benefits of the JM Aerofoil fan include compactness, low cost, high efficiency, and rugged design.
JM is available in 18 different fan diameters from
315mm (12.4”) through 2240mm (88.2”). Multiple
combinations of hub diameters, speed, number of
blades, and pitch angle assure you of a highly efficient selection to meet your application requirements.
JM Aerofoil impellers have a unique aerodynamic
blade section to optimize efficiency and performance while minimizing the noise. The thin section
high-pressure die cast technique results in high
efficiency, strength, and lower weight. All fans are
precision balanced to minimize vibration levels.
Fan casings are heavy gauge steel with spun
flanges and continuously welded seams. They are
manufactured to stringent tolerances for roundness
assuring proper blade tip clearances required for
optimal performance and efficiency. Motors are
cast iron frame, industrial duty motors with pad
mounting for superior mechanical and aerodynamic
performance. Request Bulletin JMA60-99.
Axial / Controled Blade
The Varofoil, variable-pitch-in-motion fan has been
operating successfully for many years in a wide
variety of variable duty air system applications.
Energy savings, reliability, low noise levels, and
negligible maintenance requirements are just some
of the benefits. Varofoils are typically used in air
handling systems for office buildings, hospitals,
schools, universities, theatres and a multitude of
other applications.
Variable pitch assures that high efficiency is
maintained throughout the operating range. The
Varofoil can meet the demands of virtually any type
of clean air system requirements, such as:
■ Constant pressure with varying volume
■ Constant volume with varying pressure
■ Pressure varying as the square of volume varying
Varofoil is available in 14 diameters from 630mm
(24.8”) through 2800mm (110.2”). Three different
hub diameters combined with the use of different
numbers of blades and motor speeds pinpoints
your performance requirement at optimum efficiency. Motors are cast iron frame, industrial duty
motors with pad mounting for superior mechanical
and aerodynamic performance. Request Bulletin
VF2000.
