Pasko Centrifugal
fans are widely used in the Heating, Ventilation & Air-conditioning
fields. Our products are designed to meet customers' individual
specification. Whatever the requirement, be it high efficiency,
low noise, clean air, handling light dust or large solid particles;
a suitable centrifugal fan can be found from our range.
Applications :
General HVAC& R
Material Handling
Chemical Process
Induced Draft
Dust Collection
Dust Control
Pressure Blower
Painting plants
Rotogravure
Food industry
Incinerators
Industrial processing etc.
Casing :
The fan casings are fabricated out of continuously welded heavy
gauge steel sheets with smooth exterior & interior to equalize
the flow of air over the entire outlet area. Stationary vanes
are used to increase efficiency with reduced turbulence &
noise.
Impeller :
The impellers with deep, wide blades are very rigid and efficient.
All impellers are precisely balanced both statically & dynamically
to offer balanced rotor whirl. Centrifugal fan impeller designed
by us include: backward curved, backward aerofoil, backward
inclined, forward curved, radial blade etc. Standard impellers
are made of mild steel. Stainless steel / FRP coated impellers
can also be provided
Shaft :
The shafts are liberally sized to run well below critical speed
and made of high quality hot rolled steel or alloy steel depending
on application.
Bearing :
Correct bearing design ensures long life and trouble free operation.
For standard fans heavy duty double row self aligning ball bearings
are used. Roller or Sleeve bearings can also be provided if
needed
Fan Drive Systems :
The fan assembly could be mounted on a wide range of driving
systems to meet the desired range of performances and applications.
These includes direct drive, belt drive, gear drive etc.
Fan Performance
The way Pasko fan impellers (blades or rotors) are designed,
the amount of air they can move decreases as the pressure they
are working against increases. The airflow vs. pressure information
for a particular fan is called the fan performance data. The
performance of a fan depends on the size, shape & speed
of the impeller. The fan performance data is essential for selecting
fans as per the desired airflow and system pressure.
