VD-MULTI DIRECTIONAL DIFFUSERS

Product catalog summary

Overview: The document provides detailed information about VD Multi Directional Diffusers used in HVAC systems by GMCAIR HVAC SYSTEM & EQUIPMENT LLC. These diffusers are designed to create a swirl in air conditioning systems, enhancing room ventilation with minimal turbulence.

Description: VD diffusers are ceiling swirl diffusers that facilitate mixed flow ventilation in comfort zones. They are available in two types: VD with fixed blades and VD-S with adjustable blades. These diffusers are made from extruded aluminum and are powder-coated in RAL9010 as standard.

Functionality: The diffusers have adjustable air control blades that allow for different air patterns suitable for both cooling and heating modes. They support omni-directional horizontal air discharge and vertical discharge in heating mode, with a temperature difference range from -12 to +15 K.

Installation: The diffusers can be installed using bridge, screw, or no fixing methods. They are compatible with plenum boxes and actuators for adjusting air discharge direction.

Standard Sizes: The document lists standard sizes for ceiling swirl diffusers with square diffuser faces, suitable for both horizontal and vertical duct connections.

Plenum Box Details: The plenum box includes components such as diffuser face, adjustable-fixed blades, suspension hole, spigot, cable gland, and actuator with cross bar. It supports both horizontal and vertical air discharge patterns.

Installation Options: The diffusers can be installed flush with the ceiling or protruding, with options for freely suspended installation. They allow continuous adjustment of discharge direction and are suitable for industrial zones.

Order Codes: The document provides a coding system for ordering diffusers, detailing options for blade type, neck size, frame size, mounting type, finish, and coating.

VD-MULTI DIRECTIONAL DIFFUSERS DESCRIPTION: Ceiling swirl diffusers in air conditioning systems create a swirl to supply air to rooms. The resulting airflow induces high levels of room air, thereby rapidly reducing the airflow velocity and the temperature difference between supply air and room air. Ceiling swirl diffusers allow for large volume flow rates. The result is a mixed flow ventilation in comfort zones, with good overall room ventilation, creating only very little turbulence in the occupied zone.
