DAMPERS / LOUVERS / FIRE DAMPERS / SHUTTERS Adaptable to Manual, Pneumatic or Electric Control . . . Available In Any Size and Any Material U/L Inspected Fire Damper The U/L label on fire dampers covers the design, construc tion, and automatic mechanism and further indicates they have been constructed under U/L supervision to exactly models tested ia their laboratory. AFFCO Model FR647 Dampers so labeled are available for protection of ducts passing through fire walls and for use in branch ducts as prescribed by NBFU. AFFCO Model L-FS Underwriters Laboratories' labeled fire damper now available for maximum fire haxard ap plication.' ' Specification of labeled fire dampers is your assurance of a proven,design and factory inspected construction. Tight Closing Damper A well designed factory built damper provides minimum clear ance between the ends of blades and damper frame. Dampers of lesser quality have greater clear ances. Whatever the clearance, it mnnnta to a crack through which air can leak by reason of the air pressure bearing on the damper when the blades are closed. Where tight shut-off is re quired, such as on multi-zone unit dampen, face and by-pass and fresh air dampen, a means for preventing excessive leakage is much to be desired. Affoo origi nated BLADE END SEALS are positive, permanent, effective and are suitable for temperature ranges from minus 30* to plus 300* F. Gear-Link Damper Specifications Frames--3" x x .094 Extruded Aluminum Channel. Blades--2%* wide Extruded Alumi num, airfoil shape. Linkage--Cycolac gears and shafts. Seals--Neoprene stripping along blade edges--optional where re quired for maximum shut-off.
