SPECLINE REGULATOR DAMPERS
MINIMUM LEAKAGE DAMPER REGULATORS

Specline Regulators are designed for minimum leakage applications. Each regulator is comprised of a frame, an indicator handle, a serrated cast alloy core and a cast alloy nut. Serrations on the cast alloy core mesh with serrations in the frame to firmly lock the regulator in position. A spring washer situated between the core and the cast frame allows for smooth non-binding adjustment. A wedge pin is used to eliminate rattle and take up slack between regulator and damper shafts.
All SR and SRH type regulators include a cast alloy cap nut and neoprene frame gasket. SR stands off duct 1-3/8″. SRH stands off duct 5/8″.
All SRHS, SRS and SRST type regulators utilize a stamped regulator frame. SRHS stands off duct 5/8″. SRS stands off duct 1-3/8″.
