S3CD - SQUARE 3 CONE DIFFUSER

Product catalog summary

Description: The Square 3 Cone Diffuser (S3CD) is designed with an aerodynamic backpan and cone assembly that ensures a 360° radial air pattern. It facilitates rapid air mixing, temperature equalization, and velocity reduction while maintaining low pressure drop and minimal sound generation. It is particularly suitable for Variable Air Volume (VAV) applications with high turndown rates, ensuring a stable air pattern even at reduced air volumes.

Construction: Available in Steel (S3CD) and Aluminum (AS3CD).

Application: Suitable for ceiling installations and compatible with most standard ceiling styles.

Finishing: Standard powder coating in RAL9010, with other colors available upon request.

Installation: Designed for 24” x 24” T-bar lay-in installations.

Accessories: Options include a Damper (D) and Plenum Box (PB).

Standard Sizes and Technical Drawings: The diffuser is available in a 24”x24” size, with options for configurations with or without dampers and insulation.

Performance Data: The document provides detailed performance data for various models (S3CD, S3CD-D, S3CD-R6, S3CD-DR6) across different neck sizes (6”, 8”, 10”, 12”, 14”, 15”). Key parameters include CFM (Cubic Feet per Minute), static pressure (Ps), throw distance, and noise criteria (NC). All units are tested according to ANSI/ASHRAE 70-2006 standards.

Order Code: The order code specifies the model, inlet size, frame size, and optional powder coating.

S3CD - SQUARE 3 CONE DIFFUSER DESCRIPTION: The Square Cone Diffuser (S3CD) features a highly engineered, aerodynamic backpan and cone assembly that creates a horizontal 360° radial air pattern. The S3CD promotes rapid mixing, temperature equalization, and velocity reduction with industry-leading low pressure drop and sound generation. Ideal for VAV applications with high turndown rates, the S3CD maintains a consistent, stable air pattern even as air volume is reduced, minimizing dumping and drafts.
