Frequently Asked Questions (FAQ) – OF3-20-10 Filter Element

Q1: What is the filtration principle of the OF3-20-10 Filter Element?

A: The OF3-20-10 Filter Element operates on the principle of depth filtration. As fluid passes through the glass fiber media, 

particles are captured through a combination of direct interception, inertial impaction, and diffusion mechanisms.

 This multi-mechanism approach of the OF3-20-10 Filter Element ensures high removal efficiency across a wide

 particle size range.

Q2: What media options are available for the OF3-20-10 Filter Element?

A: The OF3-20-10 Filter Element is available with four media types: glass fiber filter paper (-BN) for high-efficiency filtration,
