Features
The pressure switches of Type 604 monitor filters and fans in ventilation ducts as well as air dampers in primary/secondary controls in Δp function. The series, divided into five pressure range gradations, impresses with extreme ease of installation, combination brackets, snap-on covers, and screw terminals. Unique is the high adjustment accuracy through individual scale engraving.
