Axial Fan | FRP Fans | AirFoil Fans
The fan having airflow direction parallel to the axis of rotation known as axial fans.
Type of axial FRP fans
Tube Axial Fans
Tube Axial Fans have an axial impeller. This axial fan impeller operates inside a cylindrical housing known as fan cashing. Clearance between blade and cashing should be least to improve efficiency. In tube axial fan impeller runs faster to enable air delivery at high pressure.
Vane axial fans
van axial fan also having an axial impeller that runs inside cylindrical cashing. Additionally, the van axial fan has guide van to direct and align the airflow this increases fan efficiency.
With improved efficiency van axial fans have the capacity to handle higher static pressure. These vane axial fans are the most efficient in the industries.
Propeller fan
Propeller fans have low speed and low to medium static pressure. A large volume of air delivered by the propeller fans. The typical use of propeller fans is an indoor application as exhaust or ventilation. The efficiency of the propeller fan is low compare to tube axial fans and vane axial fans.

Airfoil FRP fans
Fans use airfoil cross-section in its blade known as airfoil fans.
What is an airfoil?
Airfoil is a cross-section used in fluid mechanics to develop objects with a high lift to drag ratio.
Understanding airfoil –
- The upper surface – convex back surface of the airfoil fan blade is the Upper surface of the airfoil.
- The lower surface – Working surface of the airfoil fan blade deliver air is the lower surface of the airfoil.
- leading-edge – the thick edge of the airfoil which faces the incoming air in the fan.
- Camber – Convexity of the airfoil from leading to trailing edges called camber.
- camber line/mean camber line – it is the mean line of the airfoil considering the camber curve.
- Trailing edge – it is the thinnest rear edge of the airfoil.
- Chord line – it is the straight line from the leading edge to the trailing edge.
- Type of fan.
- Application of fan.
- The blade construction material.
- Blade weight restriction.
- Manufacturing processes.
These airfoil fan delivers high energy efficiency. Thin airfoil selected for the metallic blade. Because in case of metal weight of the blade increased with thick airfoils.
In the case of FRP bladed fans more freedom is available to the designer. As with hollow blade construction, any profile can be used with minimal impact on weight.
In the FRP blade, airfoil selection depends on the manufacturing process. These processes are Hande mould blade, RTM blade, Pultrusion blade, etc.
Airfoil blade terminology and definitions
- Fan blade Span – Blade tip to root is the blade span.
- Fan blade Chord at the root – it is the airfoil chord at the root of the blade.
- Fan blade Chord at the tip – it is the airfoil chord at the tip of the blade.
- The leading edge of the fan blade – is the attacking edge of the blade that faces the first impact of incoming air.
- Blade tip speed – it is the leaner speed of the fan blade i.e. periphery of the blade multiplied by rpm.
- The angle of attack – it is the angle of the blade chord to the axis of rotation in the axial fan.
- Blade twist – it is the angle between the chord line of blade root and blade tip.
- Blade tip – it is the end portion of the blade it is having the highest speed.
- Blade route – it is the broadest portion of the blade.
- Blade shank – it is the portion of the blade that connects the root to the fan hub. It clamped at the hub and wears all the load of the blade.
Energy-efficient airfoil FRP fan blade
It is the blade Made of the most efficient airfoil for the application. width of the blade remains high at the root and decreases gradually toward the tip of the blade. The blade should have a twist to maintain constant air velocity from root to tip.
FRP fan blade
- FRP is the most suitable material for the fan blade.
- FRP blades are corrosion resistant and can use in steam moisture and even in an acid environment.
- FRP fan blade can be anti-static for the use of critical applications to pass the static charge.
- FRP enables hollow blade construction which gave freedom to choose the best airfoil.
- FRP having a high strength to weight ratio which enables the low weight of large fan blades like cooling tower fans and ACC fans.
- the use of a good UV additive FRP blade can achieve high ultra violate ray stability.
- FRP fan blade is easy to handle and install.
- With a high grade of resin improved abrasion resistance can be achieved.
- The surface finish of the FRP blade is far higher compare to any of the other material
What is FRP?
It is an abbreviation of Fiber reinforce plastic. To be more specific it is also called GRP glass reinforce plastic. Fiber is a general term it may be any fiber-like Glass fiber, Carbon fiber, Natural fiber, etc. But GRP is specific and it covers the broadest range of FRP.Energy-efficient axial FRP fans
It is a relative term that is why everyone claims for having there fan energy efficient. But to achieve the title of most energy-efficient axial flow fan it must have –
- An efficient airfoil should use in the fan blade.
- The fan should achieve the least tip clearance.
- The designer must have good knowledge of the fan application.
- Fan material should be able to operate in the working environment without deterioration.
- An energy-efficient fan should not be over-design or it will be less efficient at duty point.
- Also, fans should not be under design. as it will be better for efficiency but may not fulfill the airflow need.
