Description
Product Description
Jet Nozzles are used where supply air must travel a large distance to the occupied zone. Particularly suitable for large rooms (halls, assembly rooms, atria) where ceiling diffusers are not practical. ONT jet nozzles are designed so they can be adjusted to meet requirements for heating or cooling.
Long Throw Capability
Designed for throws up to 43m+ (size 350, 4 elements) — suitable for airport terminals, atria, sports halls and large retail spaces.
±30° Vertical Adjustment
Nozzle adjustable 30° upwards to 30° downwards — accommodates both heating (upward) and cooling (downward) airstream deflection requirements.
360° Rotational Mount
Nozzle mounting plate rotatable through 360° — enables fully directional air jets without moving the plenum connection.
1–4 Element Configurations
Available in single, double, triple and quadruple nozzle assemblies per face plate for increased airflow capacity.
Plenum Box Option (ONT-P)
ONT fitted to rear plenum box with rear flange connection. Plenum box gives clean installation with concealed ductwork.
Damper Option (ONT-PD)
ONT-PD includes opposed blade damper in plenum box operable with external locking lever for volume control.
