iCS GASSMITH Series Dry Scrubber Systems
High-performance dry gas abatement systems designed to treat hazardous semiconductor process gases using application-specific absorbent media.
Targeted Treatment for Hazardous Process Gases
The iCS Technology GASSMITH Series is designed to remove hazardous gases from semiconductor and industrial process exhaust using specialised absorbent media.
The gases react with the selected treatment material inside the scrubber, helping convert or capture targeted contaminants before the exhaust enters the facility exhaust network.
- Designed for hazardous and toxic process gases
- Dry treatment without continuous wet scrubbing
- Application-specific absorbent selection
- GS100, GS200 and GS400 system configurations

How Dry Absorbent Gas Abatement Works
Process exhaust passes through treatment media selected according to the target gas and application requirements.
Gas Entry
Process exhaust enters the GASSMITH system through the designated KF inlet connection.
Absorbent Treatment
The gas contacts specialised absorbent media selected for the relevant chemical compounds.
Gas Removal
Target gases are adsorbed or chemically reacted within the treatment media.
Treated Exhaust
The treated gas leaves through the outlet and connects to the facility exhaust arrangement.
Why Choose the GASSMITH Dry Scrubber Series?
Targeted Gas Treatment
Treatment media can be selected according to the specific process gas and required operating conditions.
No Continuous Wet Scrubbing
The dry-treatment approach avoids the need for a continuously operating wet scrubbing process.
Multiple Configurations
GS100, GS200 and GS400 options support different process-flow, installation and capacity requirements.
Semiconductor Applications
Designed for hazardous gas streams found in semiconductor and advanced manufacturing environments.
Additional gases and organic compounds may be treatable depending on the selected absorbent media. Technical confirmation is required.

GASSMITH Dry Scrubber FAQs
What is a dry gas scrubber?
A dry scrubber passes process exhaust through treatment media that adsorbs or chemically reacts with targeted gas contaminants.
Which gases can GASSMITH systems treat?
The available product information lists gases including AsH₃, PH₃, BF₃, SiH₄, GeH₄, DCS, TCS, Cl₂, HCl, HF, F₂, NH₃, BCl₃, WF₆ and H₂S. Suitability must be confirmed for each application.
How do I choose between GS100, GS200 and GS400?
Selection depends on gas type, concentration, exhaust flow, required media capacity, connection size, equipment footprint and available facility utilities.
Does the absorbent media need replacement?
Yes. Dry treatment media has a finite capacity. Replacement frequency depends on gas loading, operating hours, concentration and the selected absorbent.
Can one absorbent treat every process gas?
No. Treatment media must be selected according to the target gases and operating conditions. A technical review is required before confirming the appropriate media.
