Frequently Asked Questions (FAQs)

1. Do I need a filter regulator lubricator?

Yes, a filter regulator lubricator (FRL) is necessary to ensure that every tool or process receives clean, lubricated compressed air at the proper pressure for optimal performance. FRL units help maintain the quality of the compressed air supply and extend the lifespan of equipment.

2. What are the different types of air lubricators?

There are two main types of air lubricators - oil fog and micro fog. Oil fog lubricators deliver controlled lubrication to the internal moving parts of machinery and are commonly used. Micro fog lubricators provide the best atomized mist for optimal performance and reduced maintenance.

3. What kind of oil do you put in a FRL unit?

In a FRL unit, it is recommended to use SAE petroleum-based detergent automotive motor oil. If 10wt. or 20wt. oil is not available, 10w30 SAE petroleum-based detergent automotive motor oil can be used. Synthetic oils should be avoided as they may break down and form a black grease substance in the unit.

4. Does lubricator go before or after regulator?

In the air line setup, typically the lubricator is installed after the regulator. The sequence is as follows: shutoff valve, filter, regulator, and then the lubricator.

5. Where should air line filters and lubricators be installed?

Air line filters and lubricators should ideally be installed as close as possible to the point of use, within 10 meters. The filter should be the first component, followed by the lubricator. A pressure regulator should be installed after the filter, and a drip rate indicator after the lubricator.

6. What are the two types of compressor lubrication systems?

The two common systems for lubricating the pump in piston compressors are splash lubrication and pressure lubrication.

7. Where do you put an air lubricator in a pneumatic system?

In a pneumatic system, the air lubricator should be installed downstream of the filter and regulator, but upstream of the device it is intended to lubricate, such as valves, cylinders, or tools. The airflow should be from the 'IN' port to the 'OUT' port as marked on the lubricator.
