Performance |
-
We have PROPRIETARY DESIGN SOFTWARE
developed in-house for design of centrifugal fan which has been
validated after more than 600 installations . -
Proper design ensures high efficiency
of up to 85%. -
Each and every blower is tested for following -
-
Vibration free performance tested to ISO 1940 and IS 11723
-
The blower is tested for required flow rate and pressure as per IS
4894 .Tested
for bearing temperature rise.

Construction features |
-
Single piece bearing housing machined
in one setting to eliminate alignment problem during assembly and
maintenance.
-
The body is fabricated and not cast
avoiding casting defects like blowholes, porosity, hence, better
strength and rigidity.
-
Heavy-duty ball/spherical roller bearings are used for
long trouble free performance.
-
Grease lubricated for life or with re
lubrication facility.
-
Drain plug is provided for condensate
removal.
-
Access door is provided for inspection
/ cleaning.
-
Damper is provided at outlet to
control airflow rate.
-
Manometer tapings are provided at
inlet and outlet to facilitate pressure drop measurement.
-
Direct driven and belt driven
constriction is available.
-
Guards are provided at Air inlet and
belt that make installation safe.
-
Rigid base frame and supports are
provided for vibration free performance.
-
We can supply blower and fan for air /
gas temperatures between -30 Deg.C to 700 Deg.C.
-
The material of construction can be
AISI 316, AISI 310, Carbon Steel, and custom made.
-
We give low speed blowers for erosion
free performance.
|
|
Optional Instrumentation |
-
Vibration switch to give alarm if the
vibrations increase above acceptable limits.
-
Digital temperature controller to
monitor temperature of bearings.
-
Manometer to measure pressure
developed by the blower / fan.
-
Air flow measurement instrumentation.
