Arcadia Desiccant TA250-1 Mini Immersion-Proof Breather
Compact Venting Solution with Certified Immersion Resistance
The TA250-1 Mini Immersion-Proof Breather from Arcadia Desiccant is designed to withstand full immersion in water up to 1 meter deep for 2 hours with no water ingress, making it ideal for sealed enclosures exposed to harsh or wet environments.
Constructed from a modified acrylic copolymer membrane, cast on a non-woven polyester backing, and post-treated for hydrophobic performance via UV/E-beam polymerization, the breather is housed in stainless steel with a natural clean finish for corrosion resistance and durability.
