Engineered for Durability and Performance

These two way inlet impellers are meticulously constructed from robust steel, ensuring high corrosion resistance thanks to advanced coating options like powder-coating or galvanization. Designed for longevity, each impeller withstands harsh operational settings and remains reliable across a wide range of temperatures, from -20C to +80C. The backward curved blade design not only optimizes airflow but also reduces noise and vibration, meeting stringent industry standards for safety and efficiency.


Flexible Customization & Application Versatility

Suitable for HVAC, air handling units, industrial ventilation, and duct systems, these impellers offer adaptable sizing (315-1400 mm diameter) and blade configurations (8-12 per model), tailored to specific air movement requirements up to 25,000 m3/h and pressures of 1200 Pa. Whether you need flange or shaft mounting, each unit can be manufactured to your required specifications, ensuring seamless integration into any mechanical or industrial system setup.

FAQ's of Two Way Inlet Impellers:


Q: How are Two Way Inlet Impellers typically installed in ventilation systems?

A: These impellers are designed for easy installation and can be mounted either via shaft or flange, depending on your system configuration. The mechanical coupling design allows for straightforward connection to drive shafts or motors for efficient operation.

Q: What benefits does the backward curved, aerodynamically designed blade provide?

A: The backward curved blades enhance airflow efficiency and minimize resistance, which not only increases air delivery but also lowers energy consumption and operational noise, resulting in cost savings and improved performance.

Q: When should I select a custom impeller size or blade count?

A: Customization is recommended when your project requires specific performance metrics-like unique airflow rates, pressure requirements, or fitment in non-standard duct sizes. Our team can manufacture impellers with the diameter, blade count, or coatings you specify.

Q: Where are these impellers most effectively used?

A: They are ideally suited for HVAC systems, air handling units, industrial ventilation, and air duct installations, thanks to their robust construction, high performance, and adaptability to various mounting configurations.

Q: What is the process for ensuring these impellers operate vibration-free?

A: Each impeller is dynamically balanced according to ISO 1940 and AMCA standards. This process ensures smooth, vibration-free operation, prolonging equipment life and reducing noise during use.

Q: How does the high corrosion resistance benefit the user?

A: Using steel with powder-coated or galvanized surfaces ensures that the impeller maintains integrity and functionality in corrosive or humid environments, leading to longer service life and reduced maintenance requirements.
