STJH-BUBBLE-TIGHT-ISOLATION-DAMPER-610X305

Bubble-Tight Isolation Damper 610 x 305 mm

A rectangular single-blade isolator for medium-width process ducts.

One blade spans the rectangular opening without intermediate blade joints.
External sleeve bearings allow service access from the duct exterior.

Введение продукции

A double-skin rectangular blade spans a 2:1 opening and turns about its central horizontal axle. The flanged body provides a bolted interface for isolation sections where a louver-style damper would introduce several blade-edge joints.
