Fan Curve Analysis Basics
What Is a Fan Curve?
A fan curve is a chart that shows how a fan works. It helps you see how much air the fan can move. It also shows how much pressure the fan can make. The main parts of a fan curve are static pressure, airflow, and power use. Static pressure means how hard the fan pushes air against things in the way. Airflow tells you how much air the fan moves in one minute. This is measured in cubic feet per minute (CFM). Power use is how much energy the fan needs to run. When you look at a fan curve, you can find the best spot for your cooling needs. Where your system’s curve meets the fan’s static pressure curve is the best place for the fan to work.
Tip: The Air Movement and Control Association (AMCA) gives rules for reading fan curves. These rules help you pick the right fan for your job.
Key Fan Characteristics
You should know the main things to look for in fan curve analysis. Here is a table that shows the most important ones:
| Characteristic | Description |
|---|---|
| Static Pressure | The force the fan uses to push air through tight spots or filters. Higher numbers mean the fan works better in hard places. |
| Air Volume (CFM) | The total air the fan moves in one minute. A higher CFM means more air moves. |
| Brake Horsepower (BHP) | The power the fan needs to move air and make pressure. This changes how much energy the fan uses. |
Modern fans use new designs to help airflow and static pressure. Some fans, like Linkwell’s Computer Chassis Fan and Electrical Enclosure Fan, use smart controls and strong parts to work better and save energy.
Why Fan Curve Analysis Matters
Fan curve analysis helps you choose the best fan for your cooling system. You need to match the fan’s airflow and pressure to what your equipment needs. If you pick the wrong fan, your system could get too hot or waste energy. Engineers use fan curves to set limits for air speed and pressure drop. This helps you make good choices and keeps your equipment safe. You also follow the rules for airflow, pressure, and noise. Linkwell’s skill in cooling gives you products that meet these rules. When you use fan curve analysis, you get better cooling, less noise, and more efficiency.
- Knowing fan laws helps you see how fans work in your system.
- Finding the right spot on the fan curve makes sure your cooling needs are met.
- Knowing how airflow and pressure work together helps you get the best from your fan.
Reading Fan Performance Curves
Static Pressure vs. Airflow
You can learn about fan performance curves by seeing how static pressure and airflow work together. When airflow goes up, static pressure goes down. If you block the space, static pressure gets higher and airflow gets lower. An open cabinet lets the fan move the most air with almost no pressure. A closed cabinet makes the fan push against the most pressure, but airflow drops to nothing.
Note: The fan gets its highest static pressure when airflow is zero. It gets the most airflow when static pressure is zero. Every spot between these two points is shown on the curve.
Linkwell’s Computer Chassis Fan works best in open cases. It gives lots of airflow for cooling. The Electrical Enclosure Fan is made for closed cabinets. It needs more static pressure to push air through filters and tight spots.
Steep and Flat Curves
Fan performance curves can be steep or flat. Steep curves mean the fan keeps moving air even when static pressure rises. These fans are good for places with lots of resistance, like dusty or tight spaces. Backward curved fans are efficient and handle high pressure well. They are great for factories and big machines. Flat curves show fans that move a lot of air but lose pressure fast. Forward curved fans are quieter and work well in offices or homes.
| Curve Type | Best Use Case | Example from Linkwell |
|---|---|---|
| Steep Curve | High pressure, dusty areas | Electrical Enclosure Fan |
| Flat Curve | High airflow, low noise | Computer Chassis Fan |
Fan Speed and Frequency
Fan speed changes the shape of the fan curve. When you make the fan go faster, the curve moves to the right. This means the fan can move more air and make more pressure. PQ curves show how airflow and static pressure change with speed. You can use these curves to pick the right fan and fix cooling problems.
Tip: Always look at the working points on the curve. Do not pick a point past the bend, or the fan may not work as you expect.
If you need more airflow, choose a fan with a curve that meets your needs at the right static pressure. Linkwell’s fans come in many speeds and curve shapes. This helps you match the fan to your system.
