Tulopuhaltimet

Tulopuhaltimet, also known as plug fans or direct-drive centrifugal fans, are a type of industrial fan designed for applications where space is limited and efficiency is paramount. Their defining characteristic is the impeller, which is directly mounted onto the shaft of a motor. This direct drive configuration eliminates the need for belts, pulleys, or other transmission components, leading to several advantages.

The primary benefit of tulopuhaltimet is their high energy efficiency. Without the losses associated with belt drives, more of the motor's power is converted into airflow. This translates to lower operating costs and reduced energy consumption. Their compact design is another significant advantage. The absence of external transmission parts allows for a smaller overall footprint, making them ideal for installations in tight spaces, such as within air handling units, ductwork, or other machinery.

Tulopuhaltimet are known for their quiet operation. The direct connection between the motor and impeller, along with often carefully balanced impellers, minimizes vibration and noise compared to belt-driven fans. They also require less maintenance due to the elimination of belt wear, tensioning, and lubrication. This results in increased reliability and reduced downtime.

These fans are commonly used in ventilation systems for commercial and industrial buildings, HVAC systems, dust collection systems, and various process applications where efficient and reliable airflow is required. They are available in a range of sizes and configurations to suit different airflow and pressure requirements.
