Do immersion proof breathers keep out water vapor?
No. Immersion Proof Breathers block the passage of liquid water but do not stop water vapor and for more information on how these breathers work see characteristics and applications.
How long can the breather be submerged?
That depends on the rating of the specific breather. Generally, the submersion time is a minimum of one hour.
How deep can the breathers be submerged?
That depends on the rating of the specific breather. However, there are breathers that are rated to a depth of 1 meter.
Do immersion proof breathers come in different sizes?
Yes. The smallest breathers that we currently offer are the mini-immersion breathers. Please contact AGM to ask about custom sizes.
What kind of flow rate can I expect with a standard breather?
This depends on the size and type of breather. They generally have low flow rates (a few cc to a few hundred cc per minute).
Do they open and close automatically?
No. These breathers are also referred to as “free breathers” as they are always open.
