Features

Inter-Connecting
Mechanism

All Ductgard units are
driven using a unique,
patented, interconnecting
rack mechanism as
illustrated. This
intrinsically simple
mechanism has been
ingenuitively applied to
the damper and its
characteristics ensure that
all units can operate
repeatedly with faultless
precision. Added benefits
include reliability,
durability, speed and low
torque operating
conditions.

Interlocking Blade
Operation

The Stainless Steel
Blades featured on the
Ductgard units,
incorporate a fishtail edge
detail which, with the help
of the precision single
rack operation, enables
the blades to close and
interlock extremely tightly.
This provides a tough,
effective screen against
smoke and flames for its
maximum 4 hour rating.

Stainless Steel
Edge Seals

These provide effective
barriers to cold smoke
penetration and allow the
blades to expand under
fire conditions minimising
leakage at all times

1.2mm welded duct to damper
extension fitted as standard to
house control options, offers
DW142 Class C specification.

Connections to suit most
proprietary ductwork flanges
and spigots.
