Control equipment for maintaining and controlling differential pressure between rooms in clean rooms, food factories, etc. Compact controllers with built-in pressure sensors and various functions.

These devices control differential pressure between rooms to prevent cross contamination by maintaining differential pressure between rooms in clean rooms in facilities such as pharmaceutical factories, research laboratories and hospitals with high accuracy.
Clean rooms require air supply quantity control to maintain ventilation frequency and air exhaust quantity control to maintain differential pressure between rooms.
Adjustment of air supply and air exhaust quantities is necessary according to production conditions and environmental changes over time, but there is a limit to the number of man-hours and most companies cannot take many man-hours for such adjustment.
By using our company’s room pressure controllers, stable differential pressure between rooms can be maintained at all times, leading to improved safety and reduced labor costs.
