Frequently Asked Questions (FAQs)

1. What are the two types of air pressure regulators?

There are two main types of air pressure regulators: upstream pressure regulators, which regulate the pressure from the source, and downstream pressure regulators, which regulate the pressure after the filtration process.

2. Do I need a filter and regulator on my air compressor?

Yes, it is recommended to have both a filter and a regulator on your air compressor. The filter helps to ensure a clean and reliable air supply to your downstream process, while the regulator helps to control and maintain the desired pressure for your equipment. They are both important components in maintaining the efficiency and longevity of your pneumatic system.

3. How do I know what size regulator I need?

To determine the size of regulator you need, consider factors such as the minimum and maximum inlet pressure, the required outlet pressure, the type of gas to be regulated, the load/capacity rating, the desired connection size, and whether a ventless or vented regulator is required. Taking these factors into account will help you select the appropriate size regulator for your specific application.

4. Which comes first, air filter or regulator?

In the pneumatic system, the air filter should come first before the regulator. The air filter ensures that the air entering the system is clean and free from contaminants. After the filtration process, the pressure reducing valve, or regulator, is used to control and adjust the pressure of the clean air downstream.
