Intake Pressure
Pressure intake, also known as inlet pressure, refers to the absolute pressure of the air entering an air compressor. It is measured at its inlet flange and represents the pressure of the atmosphere being drawn into the machine. This measurement varies depending on factors like altitude and temperature, and it’s different from discharge pressure.
The amount of pressure in the air at the moment it enters your compressor determines the machine’s efficiency and productivity. A higher intake air density will enable the compressor to operate more efficiently and produce higher-quality air. Ensuring the highest pressure intake also prolongs the compressor’s service life, reducing the wear and tear of its internal components.

FAQs
The best way to calculate intake pressure on your air compressor is to measure the vacuum at the compressor’s intake while it’s running. The result will show you exactly the force the machine is making to get the air it needs. A lower vacuum reading with reduced suction means the equipment is functioning optimally.
You can measure intake pressure yourself or contact an expert technician to inspect the machine. The process involves connecting a vacuum gauge or manometer to a test port located directly on the inlet piping. To obtain an accurate reading, the compressor must be running at full load when the suction at the intake is at its maximum.
An air compressor increases the pressure of the air it intakes. The machine takes in ambient air and filters it, increasing its pressure and raising its temperature. The air’s density increases while its volume is reduced, resulting in a higher concentration of air molecules and causing a significant amount of the moisture to condense into liquid water.
As a general rule, the intake pressure on your compressor can only be as high as the surrounding ambient pressure. You can ensure the best intake pressure to protect your machine and make the compression process more efficient through several methods, including:
- Air filter configuration: Having a clean and properly sized air filter will ensure the least resistance to airflow. A quality filter will help reduce the pressure drop between the ambient air and intake air.
- Smart inlet piping: An efficient system with short, wide and straight pipes will have minimal friction loss. When air flows freely at the compressor’s intlet, it will have a higher intake pressure.
- Cooler air: Cooler air has a higher density with more air molecules per cubic foot, allowing the compressor to get more usable air in every cycle.
- A booster compressor: This is a second compressor that is fed by the discharge from another compressor rather than taking air from the atmosphere. It is mostly used for high-pressure application needs like laser cutting or pressure testing.
