Buying Guide for the Best 20 Inch High Velocity Fans
When choosing a 20-inch high-velocity fan, it's important to consider several key specifications to ensure you get the best fit for your needs. High-velocity fans are designed to move a large amount of air quickly, making them ideal for cooling large spaces, improving air circulation, or even drying out wet areas. Understanding the key specs will help you make an informed decision and select a fan that meets your specific requirements.Airflow (CFM)Airflow, measured in cubic feet per minute (CFM), indicates how much air the fan can move. This is a crucial spec because it determines the fan's cooling power. Higher CFM values mean more air movement, which is ideal for larger spaces or areas that need significant cooling. For small rooms or personal use, a fan with a lower CFM (around 1000-2000) might be sufficient. For larger areas like garages or workshops, look for a fan with a higher CFM (3000 and above). Consider your space and cooling needs to choose the right airflow capacity.
Speed SettingsSpeed settings allow you to adjust the fan's airflow to your comfort level. This is important because it gives you control over the intensity of the breeze. Fans typically come with 2 to 3 speed settings. If you need versatility for different situations, such as a gentle breeze for a small room or a powerful blast for a larger area, choose a fan with multiple speed settings. Think about how you plan to use the fan and whether you need the flexibility to adjust the airflow.
Noise LevelNoise level is an important consideration, especially if you plan to use the fan in a living space or while sleeping. High-velocity fans can be quite loud due to their powerful motors. Noise levels are usually measured in decibels (dB). A quieter fan (below 60 dB) is preferable for bedrooms or offices, while a louder fan (above 70 dB) might be acceptable for garages or workshops where noise is less of a concern. Consider where you will use the fan and how much noise you can tolerate.
Durability and Build QualityDurability and build quality are essential for ensuring the fan lasts a long time, especially if it will be used frequently or in harsh conditions. Look for fans made with sturdy materials like metal rather than plastic. A well-built fan will withstand wear and tear better and provide reliable performance over time. If you need a fan for heavy-duty use, prioritize models with robust construction. For occasional or light use, a less rugged build might suffice.
PortabilityPortability refers to how easy it is to move the fan from one location to another. This is important if you need to use the fan in different rooms or areas. Features like a handle, lightweight design, or wheels can enhance portability. If you plan to move the fan frequently, choose a model that is easy to carry or roll. For stationary use, portability might be less of a concern.
OscillationOscillation means the fan can move side to side, distributing air more evenly throughout the room. This feature is important for covering a larger area and preventing hot spots. If you need to cool a wide space or multiple people, an oscillating fan is beneficial. For targeted cooling in a specific direction, a non-oscillating fan might be sufficient. Consider whether you need widespread air distribution or focused airflow.
Energy EfficiencyEnergy efficiency indicates how much power the fan uses relative to its performance. This is important for keeping electricity costs down and reducing environmental impact. Look for fans with energy-saving features or certifications. If you plan to use the fan frequently or for long periods, an energy-efficient model can save you money in the long run. For occasional use, energy efficiency might be less critical.
