|
| Variable
Pitch |
|
| |
- Static
pressure can be controlled by adjusting the pitch angle of
the blade to achieve the desired duty condition
- Easy
to adjust the blade angle by just loosening the clamp bolts
|
| Tough
yet Light in weight |
| |
- Blades
are made from Epoxy composites, which has high strength/weight
ratio
- Light
weight and hollow blade combination provides easy installation
- Minimum
down time for maintenance
- Increased
gear-bearing life
|
| Erosion
Resistance |
|
|
- Application
of special Epoxy coating in the leading edge of the blade,
protects the blade against pitting and erosion
|
| Corrosion
Resistance |
|
- All
the material used in hub and blades are corrosion resistant
- Blades
: FRP Epoxy composites
- Taper
Bush & Hardware : AISI 304
- Hub
Spool & Clamps : CI (IS 210-1993 FG-220)
- Hub
Body : MS Galvanized

| Surface
Finish |
|
|
- Blades
are treated with high glossy finish
- Minimizes
frictional losses
- Contributes
in saving of energy
|
| Increased
Gear Bearing Life |
|
- Due
to light weight of the fan rotor, life of the bearing in Gear
box increase
- Maximize
the bearing change intervals
- Minimizes
the maintenance cost
|
| Power
Saving and Short Pay Back period |
|
- Due
to high aerodynamic efficiency of the aerofoil section of
the blade, Hi-flow
fans achieve considerable power saving over conventional aluminium
blades
|
| Balancing |
|
|
- Hubs
are dynamically balanced to ISO 1940-1:1986 Grade 6.3
- Blades
are statically moment matched
- Vibration
free operation is ensured by adopting CTI approved procedures
|
| Advantages |
|
| |
- Lower
operating costs
- Reduces
