Applications/Examples of results
■Supports high-precision room pressure control in sealed spaces. Ideal for counteracting room pressure hunting caused by disturbances and pulsations! ■Achieves high-precision room pressure control even in small spaces and low airflow, such as differential pressure control between small rooms and experimental booths. ■By combining with a high-resolution constant air volume device that applies the same product, even higher-level room pressure control is possible! ■Operation management through central monitoring is possible via analog input/output and communication.
