What is hvac adjustable diffuser
The diffuser is designed to distribute the airflow pattern required for cold or hot air. HVAC adjustable diffuser means that the air flow direction can be changed by adjusting the blades.
There are many different types of HVAC diffusers on the market. Each diffuser has its unique characteristics and applications. In order to determine which type of diffuser to use and why, six common HVAC diffusers are listed here: directional diffuser, linear slot diffuser, circular diffuser, vortex diffuser, double deflection diffuser and jet diffuser
What is HVAC diffuser! HVAC diffusers are used to deliver cold or hot air, depending on whether they are used for cooling or heating. The main difference between diffusers and grilles is that diffusers are usually associated with airflow control, while grilles are not. So, when we call something a diffuser, it means that we are talking about supply airflow. Similarly, most people will mention grille when discussing return air. Some common names of airflow distribution materials are diffusers, grilles, vents, registers, and louvers
Directional diffusers: most common
Directional diffusers include 4-way diffusers, 3-way diffusers, 2-way diffusers and 1-way diffusers. Directional diffusers are considered to be standard HVAC supply air diffusers. The size of directional diffuser is mostly 2 × 2 feet (W x L), they fit 2 × 2-inch ceiling. However, they have 1 × 1 foot and other sizes are available upon request. "Be careful when purchasing directional diffusers, because you need to specify whether the ceiling is measured in English units or SI units." The SI unit size of directional diffusers is 595x595mm. If the English unit directional diffuser (603x603mm) is placed on the SI unit ceiling, it will not fit. This also applies to other square ceiling diffusers. The standard directional diffuser is made of aluminum. Galvanized steel directional diffusers may rust. Directional diffusers can be seen almost everywhere, especially in office buildings and shopping centers. In particular, 4-way diffuser is the most common type of HVAC diffuser
Directional diffusers provide excellent airflow distribution. Each of them provides about 300 cubic feet per minute of air flow with low noise, which is almost inaudible. Most of them are coupled with radial damper, coronal damper or relative vane damper for air flow control. In addition, most of them are equipped with a circular to square adapter (or booster box) for flexible pipe connection. If you have a directional diffuser with a radial baffle, you can use a screwdriver to adjust the baffle to adjust the airflow without opening the diffuser.
