Frequently Asked Questions

Can LM3 be used with processing freeze-dried coffee?

Yes – LM3 is perfect for this application as it can operate comfortably down to -70°C (-94°F). However, we recommend a separate FM1 Breather Bag installed elsewhere in the system to handle the breathing/venting of the air. In other words, although the LM3 is air permeable, it needs to act as a connector, otherwise it may become clogged.
