Fan static pressure explained
What is fan static pressure
You might wonder what fan static pressure really means. In simple terms, it’s the force your fan uses to push air through obstacles like filters, vents, or tight cabinet spaces. According to HVAC industry standards, fan static pressure is the difference between the fan’s total pressure and the velocity pressure at the discharge. You can think of it as the “push” that helps air move past anything blocking its path.
Linkwell designs its ventilation systems with static pressure in mind. When you install a fan filter unit or cabinet fan in a control panel, static pressure becomes important. If your cabinet has a filter or small exhaust holes, the fan needs enough static pressure to keep air moving and prevent overheating. Linkwell’s fans are built to deliver maximum static pressure, especially in tight or high-resistance spaces. This keeps your equipment cool and safe.
Tip: If your cabinet collects dust or gets hot, check if your fan has enough static pressure to handle the job.
How static pressure is measured
You can measure static pressure using special tools in industrial settings. These instruments help you figure out if your fan is working as it should. Here’s a quick look at how professionals measure static pressure:
| Feature | Description |
|---|---|
| Measurement Accuracy | Top transmitter accuracy for low pressure ranges in air and gas applications |
| Sensor Location | Sensors placed to sense different flow components |
| Measurement Principle | Uses the Fechheimer Pitot principle to measure total and static pressure |
| Airflow Processing | Honeycomb panels straighten air for accurate readings |
Most technicians use pressure transmitters and Pitot tubes. These tools show you how much resistance your fan faces inside a cabinet or enclosure. If you see high static pressure, your fan works harder to push air through.
Air flow vs. static pressure
You might think more airflow always means better cooling, but that’s not always true. Airflow is the amount of air your fan moves, usually measured in cubic feet per minute (CFM). Static pressure is the force that pushes this air through obstacles.
Here’s how airflow and static pressure work together:
- If your enclosure is open with no obstructions, you get maximum airflow and zero static pressure.
- If you add a small exhaust hole or a filter, airflow drops and static pressure rises.
- If your enclosure is completely closed, airflow stops and static pressure reaches its highest point.
| Scenario | Description | Air Flow | Static Pressure |
|---|---|---|---|
| 1 | Open enclosure, no obstruction | Maximum | Zero |
| 2 | Small exhaust hole or filter present | Limited | Increased |
| 3 | Completely closed enclosure | Zero | Maximum |
When you choose a fan for your cabinet, you need to balance airflow and static pressure. If you have lots of filters or tight spaces, pick a fan with higher static pressure. Linkwell’s fan filter units and cabinet fans offer different models for these needs. Larger or faster fans give you more airflow and pressure. If you run fans in parallel, you get more airflow but not more pressure. If you run fans in series, you get more pressure but not more airflow.
Note: Always check the system curve on your fan’s performance chart. It shows how airflow and static pressure change together.
You can see why static pressure matters. It helps your fan push air through filters and vents, keeping your equipment cool and dust-free. Linkwell’s products make it easy to find the right balance for your control cabinets and panels.
Why fan static pressure matters
Impact on cooling and ventilation
You want your electrical cabinet to stay cool and run smoothly. Fan static pressure plays a big role in making that happen. When you install a fan inside a cabinet, it faces obstacles like filters, vents, and tightly packed wires. These obstacles create resistance. The fan needs enough pressure to push air flow through and keep temperatures down.
If static pressure gets too high, air flow drops. Cooling efficiency suffers. Your equipment starts to heat up. Motors and sensitive electronics can fail early. On the other hand, low static pressure might mean leaks or not enough air flow, which also hurts cooling performance. You need the right balance. Proper static pressure keeps air moving, removes heat, and protects your components.
Tip: Regularly check your cabinet’s air flow and pressure. This helps you spot problems before they affect your equipment.

Common mistakes with fan static pressure
Overlooking static pressure in fan selection
You might think picking a fan is as simple as matching the size or airflow. Many people make mistakes by skipping the details about pressure. Here are some common errors you should watch out for:
- You forget to calculate how much contaminated air needs to be moved. This can leave your cabinet with poor ventilation and overheating issues.
- You ignore the temperature around your cabinet. If you do not measure it, you might choose a fan that is too weak or too strong.
- You misjudge the space inside your panel. Obstructions can block airflow, making the fan less effective.
- You overlook how air moves inside the cabinet. Bad airflow patterns can create hot spots and reduce cooling.
Tip: Always check both airflow and pressure needs before you pick a fan for your cabinet.
Misreading airflow and pressure specs
It is easy to mix up airflow and pressure ratings when you look at fan specifications. If you do not match the fan’s pressure rating to your system’s resistance, you might run into trouble. Sometimes, the fan does not perform as expected. You may see poor cooling or even system failures. The problem often comes from not reading the specs carefully, not from the fan itself. Always remember that every filter, vent, or bend in your cabinet adds to the pressure the fan must overcome. If you miss this, your system can become inefficient and hard to troubleshoot.
