DAMPERS AND LOUVERS

Application and Design

Round transitions are available as a 2 in. (51mm) offset, 1 in. (25mm) offset, or size on size. Type ‘R’ transitions are centered on end of sleeve for FSD, SMD, CFSD, and VCD models. Type ‘R’ transitions are centered on end of sleeve or damper frame for FD and DFD models.

2 in. Offset, 1 in. Offset, or Size on Size

Transitions

2 in. (51mm) Offset X = D+2 in. 1 in. (25mm) Offset X = D+1 in. Size On Size X = D

X = Nominal outside dimensions of damper

frame (1/4 in. [6mm] undersize)

D = Nominal outside dimensions of round

transition (1/8 in. [3mm] undersize)

* Dimension are in inches (mm).
