The Blower Fan is a high-efficiency centrifugal impeller designed to deliver powerful and uniform airflow throughout the heating chamber of Technopack’s E-TUN-4525-H and E-TUN-4535-H shrink tunnel machines. Engineered for thermal stability and precise airflow distribution, this fan is essential for maintaining consistent shrink performance across a variety of packaging materials and product sizes.
Forward-Curved Centrifugal Blade Design
The fan features multiple forward-curved blades that generate high static pressure and air volume, ensuring thorough heat circulation within the shrink tunnel for even film shrinkage.
Durable Steel Construction with Zinc Coating
Made from stamped and formed sheet steel, the blower is treated with a zinc dichromate finish to resist oxidation and maintain structural integrity at elevated temperatures.
Precision Balanced for Quiet Operation
Dynamically balanced to reduce vibration and operational noise, the fan enhances machine reliability and prolongs the lifespan of associated bearings and motor assemblies.
Central Hub with Shaft Bore
Designed to fit directly onto the motor shaft or drive hub of the E-TUN series, the precision bore ensures secure mounting and consistent rotational performance.
High-Temperature Tolerance
Built to operate continuously in high-heat environments typical of shrink tunnel applications without deformation or performance loss.
