Most air compressors for workshops and industry operate with a tank pressure between 8 and 10 bar. The pressure the tool receives at the point of use is always lower: after system losses, it typically arrives at between 6 and 7 bar, which is precisely the range standard pneumatic tools are designed for. Setting this correctly is not only a matter of performance, but also of energy consumption and equipment service life. <\/p>\n\n

In this article, you will see what pressure each type of application requires, what happens when the compressor operates outside that range, and how to choose the right equipment based on your actual needs.<\/p>\n\n

Tank pressure vs. actual working pressure<\/h2>\n\n

There are two pressure values that should not be confused. Tank pressure<\/strong> is what the compressor gauge shows: what the unit generates and stores. Actual working pressure<\/strong> is what reaches the tool after passing through the installation, filters, dryers, hoses, and couplings. It is always lower. <\/p>\n\n

This difference, known as pressure drop, can be 1 to 2 bar in well-designed installations. That is why a compressor with an 8 bar tank pressure typically delivers between 6 and 7 bar at the point of use, which is exactly what most industrial pneumatic tools need. <\/p>\n\n

The compressor pressure regulator allows you to set the outlet pressure required by each tool. The pressure switch, in turn, controls the motor start\/stop cycles to keep the tank pressure within the configured range. <\/p>\n\n

Recommended pressure by application<\/h2>\n\n

Not all applications require the same pressure. The following table shows the typical ranges in bar for the most common workshop and industrial uses: <\/p>\n\n

Application<\/th>Recommended working pressure<\/th><\/tr><\/thead>
Spray gun \/ airbrush<\/td>2\u20134 bar<\/td><\/tr>
Tyre inflation<\/td>3\u20134 bar<\/td><\/tr>
Blow gun \/ cleaning<\/td>4\u20136 bar<\/td><\/tr>
Pneumatic stapler \/ nailer<\/td>5\u20137 bar<\/td><\/tr>
Impact wrench, pneumatic drill, sander<\/td>6\u20137 bar<\/td><\/tr>

High-pressure applications (cylinders, diving, leak testing)<\/td>13\u201340 bar or more<\/td><\/tr><\/tbody><\/table><\/figure>\n\n

The compressor should be set to a tank pressure 1 to 2 bar above the value required by the most demanding tool in the installation. This margin compensates for the pressure drop along the route to the point of use. <\/p>\n\n

Why is operating at higher pressure than necessary a mistake?<\/h2>\n\n

There is a belief that more pressure is always better. It is not. Increasing working pressure from 6 to 9 bar boosts the power of a pneumatic wrench by 50%, but it also creates a 50% overload on the tool, significantly shortening its service life. In addition, each extra bar of pressure increases the compressor\u2019s energy consumption by around 7%. <\/p>\n\n

The cumulative cost of operating 1 bar above what is necessary over the service life of an industrial installation can easily exceed the cost of the compressor itself. A properly adjusted installation always operates at the minimum pressure required, not the maximum possible. <\/p>\n\n

The opposite effect\u2014operating with insufficient pressure\u2014also has clear consequences: losing 1 bar compared to a pneumatic tool\u2019s nominal value results in a 25\u201330% loss of productivity. In a sander, for example, that 1 bar less translates into 40% more time to complete the same job. If you notice your tools are not performing as they should, before thinking about faults it is advisable to check whether the working pressure is correct. Some of the symptoms that your compressor is operating at the wrong pressure<\/a> overlap with those of other faults, so it is best to rule out incorrect settings before calling technical service. <\/p>\n\n

Pressure losses in the installation: why the compressor needs to deliver more than the tool consumes<\/h2>\n\n

Each element between the compressor and the tool causes a pressure drop: pipes, elbows, filters, dryers, shut-off valves, couplings, and the hose itself. In a well-designed installation, this total loss should not exceed 0.5\u20131 bar. In poorly sized installations, with pipes of insufficient diameter or hoses that are too long, it can reach 2\u20133 bar. <\/p>\n\n

Clogged line filters are one of the most common causes of silent pressure loss: the compressor generates the correct pressure, but the tool does not receive it. Checking and replacing filters regularly is as important as checking the compressor oil. <\/p>\n\n

To minimise losses: use pipes with a diameter appropriate to the flow rate, avoid unnecessary elbows, keep filters clean, and size the final hoses as short as possible. In industrial installations with multiple consumption points, a perimeter ring main significantly reduces pressure drop compared to a linear branch network. <\/p>\n\n

How to set the working pressure on your compressor<\/h2>\n\n

Adjustment is done via the pressure regulator, usually located next to the compressor air outlet. To obtain a real reading, always adjust with the tool running and air flowing: the outlet gauge will drop slightly compared to the static value, and that dynamic value is what actually reaches the tool. <\/p>\n\n

The pressure switch should not be adjusted to set the usual working pressure. Its function is to control the motor start\/stop cycles to protect the equipment, and it is factory-set. Modifying it without proper criteria can void warranties and compromise tank safety. If the maximum tank pressure is not sufficient for your application, the problem is not the pressure switch: the compressor is undersized. <\/p>\n\n

\"choosing<\/figure>\n\n

What type of compressor do you need based on the required pressure?<\/h2>\n\n

The maximum pressure a compressor can generate depends on its technology and the number of compression stages.<\/p>\n\n

Jender screw compressors<\/a> typically operate in ranges from 7 to 13 bar and are designed for continuous use in industrial environments where air demand is constant. They are the most efficient option for installations with several tools running simultaneously or for processes that cannot tolerate interruptions. <\/p>\n\n

The Jender piston compressor range<\/a> covers everything from 8 bar units for DIY and light workshop use to two-stage models capable of exceeding 15 bar for high-pressure applications. They are the most versatile option when air demand is intermittent or when the installation is small. <\/p>\n\n

If the application requires pressures above 13 bar on a continuous basis\u2014such as cylinder filling, leak testing, or high-pressure work\u2014a dedicated high-pressure compressor with a two-stage (or more) design is required. For that range, the Jender team can advise you on the most suitable solution. <\/p>\n\n

Jender: technical advice to choose the right pressure and equipment<\/h2>\n\n

Choosing the wrong working pressure has a real cost: higher electricity consumption, tools that wear out prematurely, and equipment operating outside its optimal point. Jender\u2019s technical team has been advising compressed air installations in industry, workshops, and professional use for years, and can help you correctly size the pressure and flow you need before you buy the wrong equipment. <\/p>\n\n
