PRODUCT SELECTION PROGRAM

The data in this section of the catalogue permits users to make quick selections and to

determine the space required by the fans, but it is primarily intended to be a

supplement to the Fans by Fantech Product Selection Program. The program has been

designed for Windows XP and later computers.

The Product Selection Program is specific to the backward-inclined single and

double-width centrifugal fans used in the air conditioning, ventilation and dust control

industries. It enables users to select the fan and get a print-out of the performance

curve and dimensions of the selected fan in the required handing. The Product

Selection Program is limited to showing handings ACW0, ACW90 and ACW180,

but others can be provided. A copy of the program on CD is available on request

or can be downloaded via the Fantech website

PERFORMANCE

The data given here, and in the Fans by Fantech Product Selection Program,

is based upon tests conducted in accordance with BS848:Part 1, 1980 for air flow

and to AS1217-Section 3.4, 1972 for noise.

CONSTRUCTION

Backward-inclined Centrifugal Fans

Both the Laminar (L) and Aerofoil (AL) rotors use the same fan casing.

The ‘L’ blade is a backward-inclined blade.

The ‘AL’ blade has a backward-inclined hollow die-formed aerofoil section.

Both designs have a non-overloading power curve.

Apart from the blades, the rotors are similar in construction, using the same backplate,

hub and inlet spinning.

Rotors are balanced, both statically and dynamically, in an electrodynamic balancing

machine to the balance quality grade G6.3.

Fan shafts are machined from Grade CS1030 bright steel conforming to AS1443-1983

and are designed such that the first critical speed of the shaft is equal to, or greater

than, 130% of the operating speed.

Re-greasable, single-row, deep-grooved ball bearings in pillow block housings are

fitted as standard, or, where the duty warrants, grease-lubricated, double-row ball

or roller bearings in grease-relieved split plumber block housings.

The casings are fabricated from fully-welded, hot-rolled steel sheet plate conforming

to AS1594-1992.
