Industrial Fan Impeller

Name: Blower Fan Impeller for Ventilation Systems – Frigate
Price: 249.00 USD
Availability: InStock

Industrial Fan Impeller must operate without inducing structural or bearing fatigue. Achieving ISO 1940 G2.5 dynamic balancing standards significantly reduces radial and axial vibration during extended operation. Precision-balanced impellers minimize load on motor bearings and structural supports, ensuring long-term stability in high-speed ventilation systems.

Overall Diameter (D)

200 mm, 300 mm, 500 mm, 800 mm, 1000 mm (Customizable as per airflow requirements)

Number of Blades (N)

5, 6, 8, 10, 12 (Depends on fan type—backward-curved, forward-curved, radial)

Blade Angle/Geometry

Backward-curved (20°–40°), Forward-curved (30°–60°), Radial (90° straight)

Material Specification

Carbon Steel (AISI 1010/1045), Stainless Steel (SS 304/316), Aluminum Alloy (6061/7075), Cast Iron

Hub Bore Diameter (d)

25 mm, 30 mm, 40 mm, 50 mm, 75 mm (Matched to motor/shaft size)

Product Description

Industrial Fan Impeller exposed to hot gas streams requires material stability beyond standard carbon steels. Fabrication using heat-resistant alloys such as SS310 or Inconel maintains mechanical integrity up to 1100°C. Proper thermal expansion allowances in hub design prevent distortion and shaft seizure under cyclic temperature loading.

Keyway/Mounting Features

Keyway (Width × Depth) – 6×6 mm, 8×7 mm, 10×8 mm Set screws, Taper-lock bushings, Flange mounting

Static & Dynamic Balance

ISO 1940-1 G6.3 (Standard) / G2.5 (High-speed precision)

Surface Finish (Ra)

3.2 µm (Standard), 1.6 µm (Smooth for high-speed applications)

Runout Tolerance (TIR)

≤ 0.1 mm (Standard), ≤ 0.05 mm (Precision-balanced)

Certification Standard

AMCA 210 (Air Performance), ISO 5801 (Industrial Fans), ASME/ANSI (Safety Compliance)

Technical Advantages

Industrial Fan Impeller must meet specific pressure-velocity requirements within confined ductwork. Backward-inclined and airfoil blade profiles are selected using computational flow simulations to reduce flow separation and turbulence. This enhances total-to-static pressure conversion while reducing system energy demand.

Industrial Fan Impeller handling acidic vapors, alkalis, or abrasive particles must resist chemical degradation. Selection of duplex stainless steels or application of ceramic/epoxy coatings ensures minimal erosion or pitting in corrosive service environments, supporting longer maintenance intervals and impeller dimensional stability.

Industry Applications

Thermal Power Plants

Industrial Fan Impeller manages high-volume flue gas extraction and draft control in boiler systems under high-temperature and pressure conditions.

Cement Manufacturing Units

Industrial Fan Impeller handles kiln exhaust, raw mill ventilation, and clinker cooling, enduring heavy dust loading and thermal cycling.

Steel and Metal Processing Plants

Industrial Fan Impeller supports furnace exhaust, fume extraction, and cooling air systems exposed to elevated temperatures and particulate matter.

Chemical Processing Facilities

Industrial Fan Impeller transports corrosive fumes and vapors, requiring material compatibility and coating resistance against acidic and alkaline media.

Pulp and Paper Industry

Industrial Fan Impeller provides drying air circulation and chemical recovery ventilation under variable humidity and moderate-temperature operating zones.

Pharmaceutical Manufacturing

Industrial Fan Impeller ensures contamination-free cleanroom ventilation and solvent vapor extraction with low vibration and particulate generation requirements.

Customizable Hub Configurations

Industrial Fan Impeller integration with non-standard motor or gearbox shafts requires tailored bore and hub configurations. H7 tolerance bores, taper-lock bushings, or spline connections are precision-machined to prevent micro-slips and reduce fretting corrosion during high-torque transmission.

Industrial Fan Impeller subjected to continuous duty must endure high-cycle mechanical stress. Stress-relieved weld zones, shot peening of high-stress areas, and FEA-validated blade root designs are used to delay crack initiation and propagation, ensuring structural integrity over multi-year operational periods.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure precise dynamic balancing of Industrial Fan Impeller for high-speed applications?

Frigate performs both static and dynamic balancing as per ISO 1940 G2.5 or tighter grades, using calibrated balancing machines. This reduces radial and axial vibrations at high RPMs, which is critical for fan longevity. Impellers are validated under simulated operating speeds to ensure stability. Frigate also offers site-specific balancing for large diameter impellers if required.

Can Frigate supply Industrial Fan Impeller suitable for variable speed drive (VFD) systems?

Frigate designs impellers with blade geometries optimized for wide operating speed ranges under VFD control. Stress and vibration analysis is done across the full RPM envelope to prevent resonance. Material selection accounts for torsional and fatigue loads due to speed variation. Frigate also provides modal analysis data when requested by the client.

How does Frigate handle impeller failure due to high-cycle fatigue in continuous-duty environments?

Frigate uses FEA tools to identify critical stress points in the Industrial Fan Impeller design. Based on results, reinforcement ribs, optimized blade-to-shroud connections, and stress-relieving weld procedures are applied. Shot peening and controlled heat treatment enhance fatigue resistance. These methods extend operational life in cement kilns, steel plants, and other 24/7 applications.

What steps does Frigate take to prevent corrosion in Industrial Fan Impeller used for chemical exhaust?

Frigate selects materials like SS316L, Hastelloy, or applies industrial-grade coatings depending on media composition and temperature. Impellers are fabricated with continuous welds and no crevices to avoid corrosion initiation points. Pre-delivery testing includes surface roughness and coating thickness checks. Frigate also supports compatibility assessment with client-supplied gas composition data.

Can Frigate design drop-in replacement Industrial Fan Impeller for obsolete OEM fans?

Frigate reverse-engineers old or discontinued impellers using 3D scanning and performance modeling. Dimensional, aerodynamic, and material specifications are matched or upgraded based on client input. Mounting interfaces, bore dimensions, and hub details are replicated exactly for seamless integration. Frigate also provides CFD reports if performance validation is needed before installation.
