PP IMPELLERS
Manufactured by Plastic Fabricators
Performance of any centrifugal blower starts with the quality of its impeller. Well-designed impeller ensures proper airflow, pressure, energy efficiency, low vibrations, and reliability of the ventilation system. Plastic Fabricators produces injection moulded Polypropylene (PP) Impellers made of virgin polypropylene and intended for industrial ventilation and corrosive process ventilation systems. They are highly resistant to mechanical impacts, light in weight, and highly resistant to corrosive gases that are used in chemical processes.
Unlike fabricated impellers composed of several elements, our impellers are produced as single pieces which ensure greater accuracy and stability of rotation. All impellers are statically and dynamically balanced in order to minimise vibrations, reduce the wear of bearings, and provide smooth and constant operation. To make assembly more protected, PP ring is attached to the blade tips, while PP cap covers metallic hub and prevents corrosive gases from reaching metallic elements. Hub bore is machined based on customer’s shaft specifications. PP impellers are available in diameters of 8", 10", 12.5", 15", 17", 21", and 24".
TECHNICAL DATA
WHAT IS A PP IMPELLER?
An impeller made from PP (Polypropylene) is an essential element that performs a function of moving the air within centrifugal blowers, exhaust systems and industrial ventilation.
The process of movement of air by the impeller occurs due to specially designed blades which accelerate the air movement from the center to the outer radius of the impeller.
Efficiency of this process depends on the blade design, balancing, rotation accuracy and material properties.
Polypropylene has been chosen for manufacturing impellers as it is resistant to corrosion, lightweight and strong. Such properties make it appropriate for use in places where the presence of corrosive gases, acid fumes, alkali vapors and humidified process air would cause the quick degradation of metal impellers.
Plastic Fabricators produces PP impellers manufactured using the method of injection molding and optimized for the maximum air flow.

OUR PP IMPELLERS
An impeller is the core part of a centrifugal blower. Although motors give rotational energy, it is an impeller that plays a role in determining the efficiency of how air gets sucked in, gets accelerated and released into the system.
Plastic Fabricators make one-piece injection-moulded Polypropylene (PP) Impellers that are made in a way that enables smooth air flow, robust mechanical behavior and long-term performance. Each impeller is constructed from virgin polypropylene material and designed in such a way as to achieve accurate dimensions in corrosive industrial environments. Each impeller is statically and dynamically balanced to reduce vibration.
One-Piece Injection Moulded Construction
While fabricated impellers consist of multiple parts that have been welded together, the PP impellers used in our range are made from one piece of molded plastic. These advantages include: Uniformity of blade design Higher precision in dimensions Better balancing due to rotation Airflow characteristics consistency Greater strength of construction The absence of blade welds also helps with better operational performance.
Manufactured from Virgin Polypropylene
All impellers are moulded from virgin polypropylene in order to ensure high-quality material and performance consistency. Properties of virgin PP include: Corrosion resistance Mechanical strength Lightweight Moisture resistance Long lifespan Such properties allow polypropylene to be used for the manufacture of ventilation equipment designed to handle corrosive process gases.
Static & Dynamic Balancing
Correct balancing is one of the main factors which affect impellers' performance. Each impeller is: Static balanced Dynamic balanced It provides the following benefits: Vibration minimisation Reduction of bearing wear Increased lifespan of the shaft Stability of airflow Smoother blower operation Balanced impellers help to avoid losses of energy due to vibration when using the blowers in continuous industrial conditions.
PP Ring on Blade Tips
Special polypropylene ring is welded to blade tips. It serves several purposes: Increases rigidity of blades Helps to keep blades aligned Increases overall structural stability Protects blades' edge parts from damage Ring also helps to protect metallic parts from corrosive fumes.
Protective PP Hub Cap
Hub is covered with special polypropylene cap. It reduces direct exposure of the hub to corrosive fumes which can be present in chemical exhaust systems. Benefits include: Higher corrosion resistance Increased durability Lifespan extension Lower maintenance needs
Custom Hub Bore Machining
Different blower manufacturers have different shaft diameters. To facilitate installation, the hub bore is machined according to the customer's shaft specifications. It allows the impeller to be used for: New blower manufacture Replacement impellers OEM equipment Retrofit applications
PP Impeller
DESIGNED FOR CORROSIVE EXHAUST
PP impellers are commonly used in industries where exhaust systems handle acidic or corrosive fumes. The chemical properties of these gases require construction materials that can withstand prolonged exposure. We produce corrosion-resistant PP impellers that operate continuously in industrial environments.

HOW A PP IMPELLER WORKS
Converting Rotational Energy into Airflow
The function of an impeller is to create airflow in a centrifugal blower.
Step 1 – Air Enters the Centre
While rotating, the impeller allows air to enter from the centre of the impeller (eye).
Step 2 – Air Accelerates
Through centrifugal force, the impeller’s curved blades accelerate the air moving outward.
This results in:
- Velocity of air
- Pressure of air
- Air flow rate
Step 3 – Air Leaves the Impeller
The accelerated air moves from the outer part of the impeller into the casing of the blower.
Step 4 – Continuous Air Movement
The whole process helps in creating airflow for:
- Industrial ventilation
- Fume removal
- Wet scrubbers
- Laboratory exhaust
- Air pollution control
The efficiency of the entire process greatly relies on the design of the impeller.
AVAILABLE IMPELLER SIZES
Plastic Fabricators offers PP impellers in several diameters depending on the capacity of blowers used.
Available standard diameters are as follows:
- 8″
- 10″
- 12.5″
- 15″
- 17″
- 21″

Choice of an impeller diameter depends on:
- Required air flow
- Static pressure
- Blower RPM
- Power of the motor
- Resistance of the system
STANDARD SPECIFICATIONS
Selection of a proper impeller is crucial for ensuring the necessary air flow and static pressure and efficiency of operation. Parameters such as diameter of impeller, RPM of impeller, blade design, shaft size and resistance in the system will affect the performance of blower.

WHY OUR PP IMPELLERS DELIVER CONSISTENT PERFORMANCE
Performance of industrial blowers greatly depends on impeller quality. The slightest dimensional tolerances can influence air flow and cause increased vibration and reduced bearing service life.
Plastic Fabricators ensures consistent performance by applying precise manufacturing for all impellers.
Consistent Blade Geometry
Injection moulding ensures blade dimensions and shapes are consistent. Contributes to: Uniform air flow Stable performance characteristics Enhanced aerodynamics Consistent manufacturing quality
Reduced Vibration
Every impeller is balanced prior to shipping. Balancing will assist in: Decrease vibration Extend bearing life Less shaft stresses Provide operating stability Supporting continual duty operation Balanced rotating elements are especially important for industrial installations operated for long periods.
Corrosion Protection
Corrosion Resistance There are often corrosive gases in industrial exhaust systems which may corrode the exposed metal components. To decrease this effect: There is a polypropylene ring welded to the blade tips. There is a polypropylene cap on top of the metallic hub. Such construction assists to decrease corrosion impact on metal parts and provide reliable long time operation.
Lightweight with Good Mechanical Strength
Polypropylene provides a good combination of strength and lightweight. Provides the following benefits in operation: Low rotational inertia Reduces bearing load Easy handling during installation Good mechanical properties
