What Size Air Compressor Do I Need

What Compressor Size do I Demand?

Ane of the biggest challenges is to correctly size your new air compressor. Similarly to everything else, new compressors available on the marketplace are more efficient and employ improve technology, therefore you have to sympathise the application and usage to size the machine correctly. Choosing the wrong air compressor for your facility can lead to bug with production and or increased costs due to wasted energy.

What amount of pressure level exercise I need?

Understanding the menstruation and force per unit area requirements for your facility is cardinal when choosing an air compressor. Pressure and menses are two very common terms used when discussing compressed air systems.

Pressure can be measured in pounds per square inch (psi), or bar (metric measure of pressure). To retrieve of this in simpler terms, force per unit area refers to the amount of force needed to perform certain amount of work at any given point in fourth dimension. A elementary example of pressure and how it works, is to imagine moving a wooden block across a table. In the illustration below, it shows that using 75 psi of compressed air is non enough strength to movement the block, merely 100 psi of pressure level has the power to move the wooden block the desired distance.

The air compressor has to provide plenty pressure to perform a given task (in this example it was to movement a wooden block). Per illustration beneath, if 100 psi is required to move the block, anything less than that volition non accomplish the task. Information technology is of import to understand what pressure is needed in order to size the compressor properly, otherwise you will exist faced with problems, similar to illustration below where lower pressure was not able to move the wooden cake, or perform the job.

What is the right air flow for my compressor?

Period, likewise referred to as free air delivery (FAD) tin be measured in cubic feet per minute (cfm), liters per second (l/s) or cubic meters per hr (m3/h) depending on your geographical location. In simpler terms, flow is the power of the compressor to keep performing a task within an adequate fourth dimension frame. The amount of flow required is adamant past the length of fourth dimension needed to consummate a given task. Allow us consider the wooden block example to explain this further. To motion a wooden block a certain distance every hr volition require less catamenia and tin can exist achieved with a smaller compressor and a storage tank. The compressor volition wheel on and off and refill the storage tank for the next time the wooden block is required to move. However, if the wooden block has to exist moved constantly within a given fourth dimension frame, a larger flow of air (or CFM) with continuous flow will be needed, thus requiring a larger compressor. If the flow is bereft, the process will crave frequent breaks while the compressor builds up pressure in the reserve tank, therefore indicating that the compressor might be undersized.

Ultimately, when you are looking to supply enough compressed air for a given awarding, it is important to consider the amount of compressed air flow (CFM) needed at a specific pressure (PSI) required for the process to work properly.

One of the ways to find out the total flow needed is to contact the manufacturer of the equipment that uses compressed air and asking data sheets with desired data. However, the best way to mensurate accurate menses, is to perform a "compressed air audit", which tin be done by a compressed air sales professional. Information technology is important to keep in mind that rotary screw air compressors tend to put out more flow per kW or HP than piston compressors.

To summarize, force per unit area (PSI) is adamant past the job you lot are performing, while menstruum (CFM) will crave the understanding of how frequently the task has to exist done, or how many jobs you are performing at the same fourth dimension. It is important to understand that under sizing a compressor will issue in pressure level drops and inability to complete a task, while oversizing the unit can pb to futurity mechanical issues and potential failure of the compressor. If you lot are unsure on how to size your new compressor for existing or new application, always contact a compressed air sales professional person for an audit.
