| Why do I need diffusers when I can simply drill holes in a length of pipe? |
|
| There are several reasons why you should use diffusers, especially in light of their relatively low cost. |
|
- Diffusers are designed to help keep the contents of your tank from entering your air supply lines and clogging them up when the blower is not operating. The membranes on coarse and fine bubble diffusers contract and serve as a check valve when air pressure is not applied internally.
- Diffusers help balance air flow because the airflow from an engineered diffuser is both predictable and consistent from one to the next. Calculating actual airflow from a length of pipe with drilled holes would be a wild guess at best, and equalizing air discharge over the full length cannot be assured.
- Diffusers generate smaller bubbles than those coming from holes drilled in pipe. A large number of small bubbles will transfer far more oxygen than a small number of large bubbles due to the increase in total bubble surface area. Therefore, when using diffusers you can achieve a desired amount of oxygen transfer with less air, and this equates to lower blower operating speeds and lower energy costs. This is especially true if you incorporate fine bubble diffusers into your system.
