Plastic Air Diffusion
Some of the many types and benefits of plastic diffusers are described in the list below.
- Plastic Air Diffusion grilles (alternatively called plastic air diffusers, air conditioning diffusers, or simply diffusers) come in a variety of sizes, shapes, and configurations. Sizes vary and include 200 mm, 400 mm, 500 mm. They are made in square, rectangular, and circular forms. While the two smaller sizes typically have a four-way blow pattern, the larger ones typically have a six-way blow pattern.
- In the square and rectangular diffusers, grilles are usually adjustable through a series of levers. This allows you to adjust them so that air flows in one, two, three, or four directions. It also allows parts of the vent to be closed, so as to minimize airflow. They can also be closed completely in the winters, thereby keeping vital heat from escaping.
- These plastic grille pieces (also called “cores”) are removable to make cleaning easier. Because dust, lint, mildew, mold, and insects are all attracted to ventilation shafts and diffusers, it is recommended that you clean your grilles once a month. This is especially important in the warmer months, when insects are more prominent and people are more likely to track in dirt.
- Plastic air diffusers belong on the outflow end of ventilation ducts. They are generally easy to install. They come standard with plastic racket clips to ensure they fit snugly on the ends of vents and don’t fall out of walls or ceilings. When necessary, you can order adapters at a low price to attach them to flexible ducting more easily.
- Circular diffusers are appropriate for reverse cycle air conditioning systems. They come with removal “biscuits” (another type of core) for easy cleaning. They are multi-directional as well, pointing in four directions in a set or adjustable configuration.
The purpose of diffusers is to maximize air flow where you need it while reducing overall heating and air conditioning costs. Though low in cost, plastic diffusers have a significant impact on your heating and cooling budget.
