Impeller/Fan for Air Blower and Damper Systems

Product Specifications

Technical details and manufacturing context for Impeller/Fan

Definition

The impeller/fan is a rotating component used in air blower and damper systems to generate airflow or pressure. It typically consists of blades mounted on a central hub, which rotates to displace air or gases for ventilation, cooling, or process applications. The impeller's performance is determined by blade geometry, rotational speed, and system resistance. Available materials include aluminum alloy, stainless steel, and engineering plastics, with material grades such as AL6061-T6 (per ASTM B221) for aluminum. Key parameters include airflow rate (500–5000 m³/h, tested per ISO 5801), static pressure (100–2000 Pa, per ISO 5801), rotational speed (500–3000 rpm), impeller diameter (100–1000 mm), blade angle (20–45°), maximum operating temperature (-40–120°C), balance quality grade (G2.5, per ISO 1940-1), surface roughness (Ra 0.8–3.2 µm, per ISO 1302), weight (5–50 kg), and IP rating (IP54–IP65, per IEC 60529). These values are reference ranges and must be confirmed for the specific model and application. The impeller is a component, not a standalone system, and its selection depends on required airflow, pressure, operating environment, and system integration. Verification of model-specific values and standards should be done with the legal manufacturer or supplier.

Working Principle

The impeller operates on the principle of rotational motion creating pressure differentials. As the blades rotate, they impart kinetic energy to the air or gas, drawing it in axially and expelling it radially or axially, depending on the impeller design (e.g., centrifugal or axial). The pressure difference generated moves the fluid through the system. Performance is influenced by blade geometry, rotational speed, and system resistance. Higher airflow requires larger impeller diameter or higher speed, while pressure capability depends on blade design and speed. The maximum speed is limited by material strength and bearing life. The impeller must be balanced to reduce vibration and noise, with a balance quality grade of G2.5 per ISO 1940-1. Surface roughness affects friction and efficiency, with a typical range of Ra 0.8–3.2 µm. Operating temperature and pressure limits must be respected to avoid material failure or insufficient sealing.
