Compressed air filters are essential to the efficient running of applications. Using the correct type of compressed air filters will be beneficial for the short term and long term in order to prevent any problems with equipment and thus saving on downtime and component replacement costs.

There are five key components of a standard air compressor:

1.       Air inlet – A female NPT thread is used to connect the air line using a choice of fittings. The cap is plumbed    internally to direct air flow downwards into the filter bowl. The spiralling action which is created removes water and debris from the air.

2.       Filter cap – This can be either plastic or metal and controls the direction of the air flow.

3.       The dotted line – This shows the path of the compressed air as it flows towards the filter discharge. In order to exit the filter, the compressed air is required to have the spiralling action and continued through the filter element, so that the air is purified further.

4.       Filter discharge – This component allows air to flow from the filter and down the air line to enter the application.

5.       Filter element – The filter element traps any debris within the air flow trying to make its way through to the application. If there is not enough air getting through to the application then always check the filter element and unclog it to allow the air to flow freely.
