SR sickle profile variable pitch axial impellers

Product catalog summary

Product Overview
SR impellers are designed with sickle profile blades and a lightweight aluminum alloy hub, suitable for applications requiring low noise emissions. They can be configured with 3, 5, 6, or 8 blades, and use TM family hubs for configurations with 5, 9, 12, or 16 blades. The blades have variable right setting angles from 20° to 37.5°, capable of producing either sucking or blowing airflow.

Applications

Animal farms
Snow cannons
Cars and industrial vehicles
Conditioners
Generator units
Axial ventilators
Earth moving machines
Radiators
Refrigeration and freezing
Heat exchangers
Cooling towers
Agricultural machinery and tractors

Product Features
SR blades are available in various plastic materials to accommodate different temperature and rotation speed requirements. The materials include Polyamide Glass Reinforced (PA6) in white or black, with operational temperatures ranging from -40°C to +120°C. Custom colors are available upon request.

Specifications and Dimensions
SR impellers can be configured with 3/5/6/8 sickle-right blades, with setting angles ranging from 20° to 37.5°. The dimensions vary by angle, with specific measurements for height (H) and width (I) provided for each angle.

Energy Efficiency
The fans have been tested in accordance with AMCA 210/07 wind tunnel standards and comply with the EU Directive 2015 on Energy Efficiency for axial fans. They are ErP2015 ready.

Performance Diagrams
Performance diagrams are provided for different configurations and rotational speeds, illustrating the relationship between airflow and pressure at various RPMs.
