JA- JET NOZZLE DIFFUSERS

Product catalog summary

Jet Nozzle Diffusers Overview
The JA Jet Nozzle Diffusers are designed for industrial and commercial applications requiring long throws and precise directional control. They are suitable for environments such as convention centers, meeting halls, airports, shopping malls, and auditoriums.

Material and Design
The diffusers are made from aluminum and feature a modern architectural style, offering an alternative to traditional diffusers with enhanced performance.

Finishing Options
The standard finish is powder-coated in RAL9010, with other colors available upon request.

Installation Methods
Options include screw mounting or no fixing. Accessories such as a plenum box are available.

Standard Sizes and Selection
The document provides standard sizes in millimeters and includes selection tables for both JA and MPK dimensions (the latter specific to the U.S.).

Performance Metrics
All data complies with ANSI/ASHRAE 70-2006 standards. Key performance metrics include:

CFM: Airflow under standard conditions.
NC: Noise Criteria curve not exceeded with a 10dB room attenuation.
Total Pressure: Measured in inches of water gauge.
Projection: Distance from the nozzle discharge to the specified terminal velocity.
Nozzle Velocity: Discharge velocity in feet per minute.
Terminal Velocity: Maximum velocity at specified distances from the outlet face.

Order Codes
Order codes specify features such as neck diameter, mounting type, damper inclusion, and coating options. For example, 'JA 00 RAL9010 SM D 315mm' indicates a diffuser without a damper, screw mounting, and powder coating in RAL9010.
