Electronic flow switch for compressed air - EFC Electronic Flow Control

Saving compressed air made easy: for many production processes with an intermittent air demand, the EFC (Electronic Flow Control) flow switch is a worthwhile retrofit.

The principle is quickly explained: when compressed air is needed, compressed air flows. When there is no demand, the switch simply closes. Reliable on/off switching ensures that no expensive compressed air is wasted.

In practice, this means, for example, that the sensor or timer controlled air valve closes when there is no part in front of the nozzle that needs blow-off or cooling.

Depending on the flow rate and the length of the pauses, this results in clearly measurable energy savings in compressed air generation.

Every cycle is different

Whether we recommend the EFC for a process depends on several factors. These include the size and complexity of the compressed air system, individual sustainability goals and any control mechanisms already in place.

We will be happy to help you determine the key figures you need and establish whether this product suits your compressed air application.

Tip: before making a decision, it can sometimes be helpful to install a loan unit first and analyse the results. If you are interested, just ask us!

Saving compressed air with demand-based on/off control

Electronic Flow Control
  • The EFC is a product developed by the American company EXAIR that controls and optimises compressed air consumption in industrial systems.
  • This electronic flow control device has sensors that monitor air demand in real time.
  • As long as the sensor detects a part, the flow stays open. Alternatively, timer-controlled cycling can be set.
  • By adapting dynamically to actual demand, the EFC helps avoid unnecessary energy consumption and reduce total operating costs.
  • The sensor has a compact design, so it can easily be fitted even where space is tight.
  • The relay is designed for a service life of at least 100,000 switching cycles.
