 Question Submitted By :: Mechanical-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
Fan, Blower & Compressors diffr in there compression
ratios.
fan compression ratios is 1.1

Blower compression ratios is 1.1 to 1.4

Compressors compression ratios is more than 1.4

A fan is used for relatively lower pressure and high volume
flow rates and a blower is used for relatively higher
pressure and comparatively less flow rates.

As per American
Society of Mechanical Engineers
(ASME) the specific ratio - the
ratio of the discharge pressure
over the suction pressure is
used for defining the fans,
blowers and compressors
Fans - Up to 1.11
Blowers- 1.11 to 1.20
Compressors - more than 1.20
 
Is This Answer Correct ?    15 Yes 2 No

fan is just used for air moving.Its blade are axailly bladed.
fans usually move large volumes of air at low pressure.
blower is a centrifugal fan,blower is a machine for moving
volumes of a gas with moderate increase of pressure.

Answer
# 8
fans has a compression ratio upto 1.1
blowers have compression ratio from 1.11 to 1.20
compressors have compression ratio above 1.20
 
Is This Answer Correct ?    9 Yes 0 No

Answer
# 9
IF THE COMPRESSION RATIO IS 1: 1, THAT IS FOR FAN,

IF THE COMPRESSION RATIO FROM 1:1 TO 1: 4, THEN IT IS
BLOWER,

IF THE COMPRESSION RATION IS ABOVE 1:4, THAT UNIT IS CALLED
AS COMPRESSOR
