KAM-W-ACTIF
Thermodynamic Nozzle Jet Diffuser – Surface Mount
KAM-W-ACTIF is ideal when supplying both heating and cooling from the wall in large rooms. Nozzle jet diffusers provide very long throw for large spaces. They’re designed to achieve long projections without the use of Coanda effect. However, their long throw is also greatly affected by the natural effect of hot air going up and cold air going down. This often results in stratification, thermal discomfort and waste of energy. In order to counter that effect, KAM-W-ACTIF will self-adjust itself to send hot air downward 30 degrees and cold air upward 30 degrees.
ACTIF diffusers are self contained units which are automatically actuated by thermoreactive elements. They don’t require any power, configuration, controls nor maintenance.
KAM-W-ACTIF is made of aluminum and is suitable for drywall and other surface mounted applications. A removable rim hides the screws once installed, allowing for smooth lines and appealing design.
KAM-W-ACTIF is a perfect example of how EffectiV diffusers can combine architectural appeal, thermal comfort and energy efficiency benefits, all in the same product.

Description
The KAM Series aluminum adjustable punkah nozzle jet diffusers by EffectiV have been designed specifically to provide air diffusion from the sidewall in very large spaces. They can achieve a very long throw for both heating and cooling whilst given flexibility in direction.
Three methods of adjustment are available: manual (KAM-W and KAM-D), thermodynamic (KAM-W-ACTIF and KAM-D-ACTIF) and actuator-controlled (KAM-W-M5 and KAM-D-M5).
The design is the result of a collaboration of MADEL® and Benedito Design with the goal to provide a diffuser that encompasses smooth modern aesthetic lines appealing to the architectural market while providing a unique performance for specific applications.

They’re ideal for reaching long distances without the use of Coanda effect. However, their long throw is also greatly affected by the natural effect of hot air going up and cold air going down.

PART 1 – GENERAL
1.1 SUMMARY
A. Long throw jet nozzle supply diffuser(s) that autonomously adjust jet angle in response to supply air temperature using a thermodynamic piston, without controls and without electricity.
B. Adjustment time: approximately 30 minutes to transition between horizontal and vertical discharge modes.
C. Mounting types:
- KAM-ACTIF-W: Surface mounted; includes a removable rim to conceal mounting screws after installation.
- KAM-ACTIF-D: Duct mounted.
D. Construction: aluminum.
E. Thermodynamic actuator system: Actuator and thermodynamic mechanism shall be fully concealed within the product and not visible from the occupied space.
F. Autonomous operation: System shall be fully autonomous and shall require no controls, no electricity, and no wiring of any kind.
G. Factory configuration: System shall be factory pre-configured and shipped ready to install; no field adjustment, calibration, or configuration shall be required.
H. Finish: factory powder coated (TGIC-free), white RAL 9016 unless otherwise scheduled.
1.2 SUBMITTALS
A. Product Data: Manufacturer’s data for scheduled model(s), available sizes, and mounting type(s), including:
- Recommended airflow range and free area (as published).
- Pressure loss and diffuser-generated NC.
- Throw data with ceiling effect (Coanda) and without ceiling effect (as published).
- Temperature differential correction factors for throws (as published).
- Thermodynamic piston description and published adjustment behavior (horizontal/vertical transition).
- Installation/mounting details and service considerations.
B. Shop Drawings: Indicate model designation, mounting type (surface mounted or duct mounted), available size selected, finish, installation details, and service clearances. For -W models, indicate removable rim detail and required orientation.
C. Airflow Prediction Report (Required – SelectiV): Provide a manufacturer-generated SelectiV airflow prediction report for each diffuser type and each distinct room condition using manufacturer performance data and recognized airflow physics corrections (ΔT correction factors, Coanda effects, buoyancy effects, jet interaction, and wall/floor/ceiling collision effects). Report shall include:
- 3D room model with diffuser locations.
- Predicted airflow visualization views: plan (top), section (side), elevation (front).
- Throws for terminal velocities of 150, 100, 60, 50, 40, 30, and 20 fpm.
- Pressure loss at scheduled airflow.
- Diffuser-generated NC at scheduled airflow.
- Perceived NC at room center (5 ft height) from all sources combined across 63–8000 Hz octave bands; include key assumptions used.
D. Verified CFD Validation (When Indicated): Provide EffectiV Verified CFD validation and summary report for spaces indicated and/or when operation is outside published selection limits.
1.3 SUBSTITUTIONS
A. Substitutions per Division 01. Proposed equals shall provide a line-by-line compliance matrix including all Part 1 deliverables, including the SelectiV Airflow Prediction Report deliverables, and confirm autonomous thermal adjustment without controls/electricity.
