I.D & FD Fans

HUMIAIR fans are of sheet steel construction with backward curved self cleaning blades. The self – cleaning efficiency of an induced draft fan will increase when the tip angle of the blade is enlarged.

These fans are, therefore, suitable for:-
Kitchen Exhaust
Dust Collector System
Fume Exhaust
Welding Shops
Pharmaceuticals
Chemicals
Engineering Industry
Automobiles

Induced Draft
Type Total Pressure mm WG
AMRL 300
AMRM 600
AHRM 900

These fans are available for air quantity from 500 CMH to 10,000 CMH.
Fans that are used to evacuate a space or create negative air pressure in a system are referred to as induced draft fans. Occasionally, manufacturing spaces are required by specifications to be maintained at a specific negative pressure. Induced draft is also used to identify the combustion process used in large boilers. When mechanical ventilation is supplied to these boilers, the heat transfer rat e increases; the boiler can be reduced in size to produce the same amount of energy as natural draft. The induced draft fans used in combustion systems are normally high temperature and extra heavy-duty construction.

HUMIAIR fan wheel has backward curved blades and is designed for either clockwise or anti-clockwise rotation. The blades and wheel are aerodynamically formed to ensure highest efficiency.
APPLICATIONS:
Forced Ventilation
DC Motor Ventilation
Drying Application
Wire Drawing
Dust Proofing / Pressurization

Forced Draft
Type Total Pressure mm WG
ACBL 110
AMBM 600
AHBM 900
AHBH 1200

Air Quantity ranges for air quantity from 500 CMH to 1,50,000 CMH.Fans that are used to pressurize a space or create mechanical air pressure in a system are referred to as forced draft fans. Occasionally, manufacturing spaces are required by specifications to be maintained at a specific positive pressure. This requirement is common in clean room processes for scientific work. Forced draft is also used to identify the combustion process used in large boilers. When mechanical ventilation is supplied to these boilers, the heat transfer rate increases; the boiler can be reduced in size to produce the same amount of energy as natural draft.
