𝐏𝐨𝐫𝐞𝐭® 𝐂𝐨𝐚𝐥𝐞𝐬𝐜𝐞𝐫 𝐌𝐞𝐝𝐢𝐚
For efficient removal of entrained droplets and coarse particles.

Poret® Coalescer Media is ideal as an initial filtration stage, protecting downstream filters from coarse particulates and entrained water droplets in inlet air systems.

🔹 Exceptional rigidity—far stronger than synthetic or glass fiber media
🔹 Maintains structure even in high water-content air
🔹 Superior water resistance for long service life
🔹 Washable and reusable without loss of efficiency

A durable and cost-effective solution for demanding air filtration environments.
