Linear Multi-Jet Ceiling Diffuser

SMARTEMP Linear multi-Jet Ceiling Diffuser, type LJC-AD: designed for high discharge heights; optionally available with thermal-element or electric cooling/heating discharge direction adjustment.

High capacity, high induction, 1-way blow or 2-way blow linear ceiling diffuser with 1-to-6 slots, each with multiple barrel nozzles discharging alternating multi-jets, suitable for high discharge heights and large volume spaces. Multi-jets adjustable through 90° (manually as standard; optionally by thermal or electric actuator for diffusers with 2 or more slots) to alter the air pattern from horizontal (cooling) through diagonal to vertical (heating).

Suitable for low temperature supply air (≥ 5°C) and CAV or VAV systems with extended turndown.

Nozzle barrels may be rotated to shut off airflow in segments, creating active and inactive portions (beneficial for achieving uniform aesthetics).

Installation flush with ceiling or free-hanging. Modular, continuous, flanged and flangeless options available. Mounting frame optional.
