Blower question. Is starting a blower "in the free" a heavy start ?

Starting a blower "in the free" refers to initiating the blower operation without any load or attachment. This article aims to address whether this method subjects the blower to a heavy start, thereby impacting its operational efficiency and longevity. ## Understanding Blower Start Mechanisms Blowers are an essential part of many industrial and domestic applications, playing a critical role in ventilation, cooling, and air movement. The start mechanism of a blower can significantly affect its performance and wear and tear over time. ### Types of Blower Starts 1. **Loaded Start:** When the blower starts under load conditions, meaning it is connected to the vent or system it will be working with. 2. **Free Start:** Otherwise known as starting "in the free," this is when the blower starts without any load or attachment. ## Analyzing Free Starts ### Mechanical Impact In general, starting a blower in the free can have a lower mechanical impact compared to a loaded start. The absence of initial resistance allows the blower to ramp up to its operating speed more smoothly, reducing the initial mechanical stress on the motor and blades. ### Electrical Considerations While the mechanical stress is minimized, free starts might sometimes lead to higher starting currents for a brief period. However, modern blowers come equipped with soft-start mechanisms to mitigate this transient higher current. ## Recommendations Industry experts and companies like HAIYANG recommend starting blowers in the free, especially for new installations or systems requiring frequent starts and stops. This practice not only extends the life of the motor but also ensures smoother operations. ### Expert Insights Establishing contact with industry influencers like Joe Johnson from HVACR School or Lisa MacLeish from BlowerFanTech provides valuable insights into contemporary practices and innovations in blower technology. ## Conclusion Ultimately, starting a blower "in the free" is generally considered a less stressful option for the blower mechanism and can promote longevity and efficiency.
