STjh VOC AMC filter FFU with twin activated-carbon service drawers and downstream ULPA filter

STJH-AMC-CHEMICAL-FILTER-FFU-VOC

Chemical Filter Fan Filter Unit VOC AMC

An organic-vapour AMC stage for VOC- and siloxane-sensitive clean manufacturing processes.

Targets VOCs and siloxanes
Activated-carbon adsorption stage
FFU adaptor with HEPA or ULPA downstream filtration

Introduction de produit

The VOC configuration uses an activated-carbon stage to target organic vapours and siloxanes before air reaches the fan filter unit's HEPA or ULPA stage. It differs from the acid and base models through the selected contaminant class and adsorbent duty. An adaptor frame integrates the chemical stage with the FFU, allowing molecular and particulate filtration to be maintained as separate, serviceable functions.

Key Features

Organic-vapour duty

The adsorption stage is selected for VOC and siloxane loading rather than acidic or alkaline contaminant chemistry.

Separate particle barrier

A downstream HEPA or ULPA filter continues to control particles after the molecular stage.

Adaptor-frame installation

The chemical panel is integrated through a sealed frame so it can be serviced independently of the primary FFU housing.

Applications

Suitable for optics manufacturing, hard-disk production, semiconductor processing and other clean areas affected by organic molecular contamination. Carbon selection and service life should be based on the specific VOC mixture, concentration, humidity and required removal level.

Solutions for Your Application

Organic vapours pass through a particle filter and can deposit on sensitive surfaces.Add the VOC-targeted activated-carbon panel ahead of the FFU and final particle stage.

A generic carbon grade may saturate quickly under the actual solvent mixture.Characterize the VOC load and select the media quantity and replacement plan around expected breakthrough.

Options disponibles

Define the target VOCs or siloxanes, media grade and depth, FFU adaptor, final filter and monitoring method. Confirm the chemical stage under the real airflow and environmental conditions.
