Centrifugal Fans

Centrifugal Fans have a wide range of applications in various industries. Industries having problems in air pollution, ventilation and other complexities of air/gas handling, are becoming increasingly aware of the comprehensive services in design, development and manufacture of INDVENT's Industrial Centrifugal Fans.

Fan Types

Fans for Ventilation and Air Conditioning

INDVENT Centrifugal Fans Types IFLL-S & IFLL-D are designed for high volume, low pressure duties with low noise level, thus making them suitable for air conditioning, ventilation & humidification systems.

These fans are generally available in welded construction & hence are robust & sturdy. INDVENT offers 3 types of construction - from 15 mm WG to 300 mm WG of static pressure - suitable for dust free air.

ID and FD Fans

The ID & FD fans are carefully designed to meet all requirements for various industrial applications. Optimised for moderately dusty air, they are of heavy duty construction with statically & dynamically balanced impellers & give trouble free operation. There are 3 basic types of fans with 25 sizes.

High Pressure Fans

INDVENT makes IHBH & IHSH series fans having statically & dynamically balanced impellers. These develop pressures upto 1000 mm WG. These are suitable for dust free air & are available in different models, for air quantity 300 m/hr to 9000 m/hr.
