Ceiling Fan Installation / Selection Guide

INSTALLATION OF ONE UNIT CEILING FAN

The main features of a ceiling fan is to move the entire air in the room, not creating a local wind as in other fans.

To determine the model and mounting position, consider the condition below :

H : distance from blade to floor (m)
R : radius of effective floor space of wind spread (m)
S : effective floor area (m2)

Calculation Formula :
R : coefficient x H
S : hR2 , where h = 3.14

Size of Blade H (m) S (m2) Coefficient
120 cm 2.5 8.3 0.65
150 cm 3 12.5 0.66

CALCULATION IF MORE THAN ONE UNIT REQUIRED

L : Distance between Ceiling Fan to another (pitch in M)
A : Distance of overlapping air throw between fan
B : Distance between tip of fan to wall
BL : Blade length (M)
L : (RX2) – 0.4, where 0.4 is maximum allowable overlapping of air throw between fan
L : (RX2) – 0, if minimum A = 0

To calculate B = R – BL
