STJH-BUBBLE-TIGHT-ISOLATION-DAMPER-1219X406

Bubble-Tight Isolation Damper 1219 x 406 mm

A wide single-blade isolation assembly for substantial containment branches.

The low, wide format fits shallow rectangular duct envelopes.
A continuous blade avoids a row of independently sealed louvers.

Introdução do produto

The elongated frame carries one double-skin blade across a broad, low passage. Its full-length axle supports coordinated movement of the wide leaf, and the perimeter seal is mechanically attached so the sealing element remains replaceable.
