Impeller Ø 200/65 mm - closed S0166

Product detailed description

Impellers are essential components in solid fuel boiler systems where controlled airflow is required for efficient combustion. This impeller is designed for use in industrial and residential installations where forced air circulation is necessary for maintaining stable burning conditions and heat distribution. Installers typically work with these parts during replacement or repair of existing ventilation systems, ensuring correct fit and function within the boiler casing. The closed design minimises air leakage and ensures focused airflow, making it suitable for systems requiring precise air volume control.

The impeller is commonly found in installations where solid fuel boilers are integrated with ducting systems or heat exchangers. It supports both primary and secondary air supply functions, depending on the boiler configuration. Technicians must ensure the impeller aligns with the motor and housing geometry to avoid mechanical stress and vibration during operation. The compact dimensions allow for use in space-constrained boiler casings while maintaining sufficient airflow capacity for standard load profiles.

Technical parameters

The diameter of 200/65 mm indicates the outer and inner dimensions of the impeller, which are critical for matching the fan housing and ducting system. The closed construction ensures higher static pressure generation compared to open designs, making it suitable for applications with longer duct runs or higher resistance. These dimensions also determine the airflow capacity and must be verified against the original equipment specifications to ensure proper system performance.

Installation and connection

Before installation, verify the impeller matches the motor shaft diameter and housing bore to prevent misalignment. The impeller is typically mounted using a keyed or splined shaft connection. Ensure the surface finish of the shaft and housing is free from burrs or damage that could affect balance. Secure the impeller using the recommended fastening method, usually a retaining ring or set screw. After installation, perform a visual inspection for clearance between the impeller and housing to avoid contact during operation. Common installation errors include incorrect alignment, which can cause vibration and premature wear, and over-tightening of fasteners, which may distort the impeller or housing.

Compatibility and accessories

This impeller is compatible with the DC105S, DC150S and UCJ4C102(J22RR552) fan models. For complete system functionality, ensure the motor and housing are in good condition and properly aligned. Additional components such as sealing rings or vibration isolators may be required depending on the installation environment. No specific accessories are listed in the technical documentation for this model.

Technical background for designers

The impeller operates by converting mechanical energy from the motor into kinetic energy in the form of air movement. The closed blade design increases static pressure and reduces turbulence compared to open impellers, making it suitable for applications with moderate resistance. The material properties ensure durability in environments with fluctuating temperatures and particulate-laden air. The integration into the boiler system depends on the motor power and housing geometry, which must be optimised for the intended airflow rate. System efficiency is influenced by the impeller-to-housing clearance and the smoothness of the internal surfaces, which should be minimised to reduce friction losses.

Service and operation

During routine service, inspect the impeller for signs of wear, corrosion or imbalance. Clean the blades to remove dust or debris that may affect airflow or increase vibration. Check the fastening elements for tightness and signs of loosening due to operational stress. No specific service intervals are provided in the technical documentation for this model. Replace the impeller if any deformation or damage is detected that could compromise performance or safety.

Frequently asked questions
