  • Airflow from 50 to 80,000 CFM;

  • Rotor depth 2", 4", 8" and 16". 

VOC Concentrator

For many years, air pollution has been a global issue. There are various causes of air pollution. Volatile Organic Compounds (VOC) is one of these causes.

Efficient treatment of VOCs allows for smaller system design, and supports economic development in terms of both environmental protection and energy conservation.

VOC concenntrators from Seibu Giken designed to selectively adsorb harmful VOCs and emit purified air.
