Pressure drop is a huge concern in compressed air. In many applications
high pressure drops will cause a decrease in the pressure at the point of use.
Sometimes this low pressure is not enough for the machines or processes
to perform correctly. In addition, dirt particles and oil in the compressed air
system may block the filters quickly. It is important for the end users and service
technicians to recognize if there is a problem in the system. The performance of
the filters directly affects the pressure drop and system performance. Therefore,
it is very important that the filter elements are changed at the filter service time.
An alarm/warning indicating that the filters are changed periodically is provided
by a digital controller on the Mikropor Air Dryer. When this alarm triggers,
the filter must be changed to avoid loss of performance and pressure drop.
