Fan/Blower Assembly

The Fan/Blower Assembly is an optional component of an Ionizing Bar designed to actively propel ionized air over a target surface or area. It typically consists of a motor, impeller blades, and a housing, working to overcome ambient air resistance and ensure consistent, directed delivery of ions for effective static charge neutralization in industrial environments. The assembly is available in configurations that support airflow rates from 120 to 340 m³/h and static pressures from 120 to 380 Pa, as measured per ISO 5801. Fan speed is adjustable between 1400 and 2800 rpm, allowing operators to tailor airflow to specific application requirements. The unit operates on a 24 V DC supply (±10%) and consumes between 15 and 60 W, depending on the speed setting. Noise levels range from 55 to 70 dB(A) at 1 meter distance, per ISO 3744. The housing is constructed from aluminum alloy (AL6061) or plastic (e.g., PBT, PC), with steel components where required, and offers ingress protection ratings from IP54 to IP65 per IEC 60529. Operating temperature range is -10 to 50 °C in non-condensing environments, per IEC 60068-2-1. The assembly weighs between 2.5 and 4.5 kg, varying with motor size. These specifications are reference ranges and must be verified with the legal manufacturer or supplier for the specific model and application. The assembly is intended for use in machinery and equipment manufacturing, particularly in static control systems where passive ionizing bars may be insufficient. It is not a standalone product but a component that integrates with an ionizing bar. For procurement, confirm compatibility, performance parameters, and applicable standards with the supplier.

An electric motor rotates an impeller (fan or blower wheel), creating a pressure differential that draws in ambient air and forces it through or past the ionizing elements of the bar. This accelerated airflow carries the generated ions to the workpiece, improving the speed and range of static elimination compared to passive (fan-less) ionizing bars. The airflow rate and static pressure are key parameters that determine the effectiveness of ion delivery, especially in environments with duct resistance or long distances. Adjustable fan speed allows fine-tuning of airflow to match process requirements. The housing and materials are selected to withstand industrial conditions, including dust and moisture, as indicated by the IP rating. Proper installation and maintenance, such as cleaning the impeller and ensuring unobstructed airflow, are essential for consistent performance. If airflow decreases or noise increases, it may indicate blockage or wear, requiring inspection. The assembly is not designed for explosive atmospheres unless explicitly specified by the manufacturer.
