Industrial Mixed Flow Fans combine axial airflow capacity with higher static-pressure capability for inline industrial ventilation. The mixed-flow impeller provides straight-through airflow with reduced system resistance, making the fan suitable for duct systems requiring both high airflow and elevated static pressure.

Impeller & Airflow Design
Mixed-Flow Impeller: Axial and radial airflow combination delivers elevated static pressure in standard inline duct configurations.
Straight-Through Airflow Path: Coaxial inlet and outlet simplify direct duct connection and help avoid additional bends and associated system pressure losses.
Drive System
Direct-Drive Construction: The impeller mounts directly to the motor shaft, removing belt and pulley components and reducing belt-related maintenance requirements.
Variable Speed Control: VFD-compatible motor configurations allow airflow and fan speed to be adjusted according to system demand.
Construction & Materials Options
Casing Materials: Heavy-gauge Q235/Q355 carbon steel with welded structural flanges, or 304/316L stainless steel for corrosive or washdown environments.
Protective Coatings: Industrial epoxy primer with polyurethane topcoat; customizable dry film thickness (DFT) per project specs.
Impeller Options: Aluminum alloy, stainless steel, or non-sparking copper-alloy impellers are available according to airflow, temperature, corrosion, and application requirements.
Particulate & Gas Handling: Suitable for clean air and light particulate streams. Anti-corrosion lining options are available for specified chemical air applications.
Noise & Reliability
Sound Pressure Levels: 58–84 dB(A) at 1.5 m, depending on model and operating point.
Dynamic Balancing: Impellers are dynamically balanced to ISO 1940-1 / applicable balancing requirements, with G2.5 available where specified.
Bearing Life: Bearings are selected for continuous-duty operation, with L10 life calculations available based on the selected operating conditions.
Acoustic Attenuation: Optional matching duct silencers and double-skin insulated casings for noise-sensitive installations.
Engineering & Customization
Precision Sizing: Engineering selection is based on the required airflow, static pressure, operating temperature, and duty point.
Custom Mechanical Modifications: Casing length, flange drilling, wall thickness, and mounting foot placement tailored to legacy retrofit dimensions.
Submittal Package: Full technical datasheets, performance curves, 2D/3D CAD drawings, wiring diagrams, and testing certificates provided with quotation.
Installation
Duct Connection: Direct inline flange mounting with ANSI or DIN bolt pattern options.
Mounting & Alignment: Fan housing and mounting supports are positioned to maintain shaft alignment and provide adequate clearance for duct connection and motor access.
Vibration Isolation: Spring or neoprene isolators and flexible connectors can be installed between the fan and ductwork to reduce vibration transmission to the supporting structure.
System Integration
Multi-Fan Arrays: Multiple fans can be configured in series for higher system pressure or in parallel for increased airflow, subject to system and fan selection calculations.
Isolation Accessories: Compatible with spring/neoprene vibration isolators and flexible canvas/silicone expansion joints.
Compliance
Electrical & Mechanical QC: Checks include winding resistance, earth continuity, shaft runout/concentricity, running current, and overall mechanical condition.
Quality Management Systems: The factory operates under certified ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 standards.
Regional Compliance: EAEU Declaration of Conformity available.
FAQ
Q: Can you provide a representative mid-range model?
A: The IMF-560 provides 12,000 CFM at 900 Pa with a 15 kW motor and 560 mm impeller, subject to the specified operating conditions.
Q: How does noise vary by fan size?
A: Units under 400 mm produce 58–65 dB(A), 560–800 mm models 68–75 dB(A), and units over 1,000 mm 78–84 dB(A) at full speed.
Q: What is the typical L10 bearing life?
A: For continuous S1 operation at rated conditions, selected bearings can provide approximately 40,000–50,000 hours of calculated L10 life, depending on load, speed, temperature, and lubrication conditions.
Q: What is included in the submittal package?
A: It includes datasheets, performance curves, CAD drawings, wiring diagrams, and test certificates, prepared within 5–7 working days after confirmation.
Q: What payment terms apply?
A: Standard units require a 30% deposit, with balance due before shipment. Custom modifications require a 50% deposit for non-returnable tooling.
Q: How does the 150°C option differ?
A: The 150°C option uses heat-resistant materials and Class H insulation selected for elevated-temperature operation. Final temperature rating and component configuration are confirmed according to the required operating conditions.
