Introduction de produit

This carbon formulation is impregnated for basic contaminants, particularly ammonia and amines. It can be incorporated into a pleatable nonwoven for compact filters or used as loose fill where a deeper reaction bed is required. Low-outgassing options suit semiconductor environments, but media quantity and replacement timing must be calculated from the measured base load because pressure drop does not indicate chemical exhaustion.

Key Features

Base-specific chemistry

The impregnation is selected to retain basic gases that untreated carbon may hold poorly.

Compact or deep-bed conversion

Pleatable sheet supports low-profile filters while pellets provide larger chemical inventory.

Sensitive-process material control

Cleanroom-oriented carrier and adsorbent choices reduce unnecessary emissions near lithography areas.

Applications

For semiconductor lithography, coating and other clean processes where airborne ammonia or amines can affect yield or product surfaces.

Solutions for Your Application

A general VOC carbon stage provides little usable capacity for ammonia.Use a base-target impregnation and size the media inventory from measured ammonia and amine concentration.

The filter is changed by pressure drop after the chemical media has already broken through.Set replacement from exposure calculations, media samples or downstream AMC monitoring independent of particle resistance.

Options disponibles

Confirm ammonia and amine profile, impregnation, media loading, format, carrier cleanliness, humidity, airflow and monitoring method.
