Immersion Proof Breathers – FAQs


Do immersion proof breathers keep out water vapor?

No. They block the passage of liquid water but do not stop water vapor.

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 immersion proof breather?

This depends on the size and type of breather. Immersion breathers generally have low flow rates (a few cc to a few hundred cc per minute).

Do immersion proof breathers open and close automatically?

No. Immersion proof breathers are also referred to as “free breathers” as they are always open.
