Product Introduction

This VOC filter contains virgin coconut-shell or coal-based activated carbon selected for non-polar organic vapours. The adsorbent is packed into a rigid V-bank or box cell to combine a large media mass with practical airflow. Internal screens and seals eliminate edge bypass and limit carbon fines. It is commonly preceded by particulate filtration so dust does not block the carbon pores, and it may be followed by a final filter where product cleanliness is critical.

Key Features

Microporous activated carbon provides a broad adsorption surface for many organic vapours.

A deep or V-bank bed carries substantially more adsorbent than a thin carbon pad.

Internal media screens reduce carbon migration into the downstream system.

Gasketed frame interfaces suit front- or side-access filter housings.

Customer Product Concerns

Low-boiling solvents and process VOCs pass through particle filters and may contaminate products or create persistent odour.

A carbon-coated pad saturates quickly during routine solvent use.A deep bed increases usable carbon mass and extends the adsorption interval.

High humidity occupies adsorption sites and shortens filter life.Media grade and airflow residence time are selected for the expected humidity and VOC family.

Dust loads the carbon surface before it can adsorb vapour.An upstream fine-particle stage protects pores and preserves molecular capacity.

Unsealed filter edges let untreated air bypass the media bed.Continuous gaskets and bonded internal joints close the frame-to-housing path.
