Compressed air lubricators are essential components in pneumatic systems, ensuring smooth operation and extending the lifespan of equipment. These devices are designed to deliver a precise amount of lubrication to the compressed air, which in turn reduces friction and wear on moving parts. By introducing oil mist into the system, compressed air lubricators provide continuous lubrication to valves, cylinders, and other components. This not only enhances performance but also prevents corrosion and helps maintain optimal efficiency. With their compact and reliable design, compressed air lubricators are a valuable addition to any industrial or commercial setting.

Frequently Asked Questions (FAQs)

1. What does a compressed air lubricator do?

A compressed air lubricator adds controlled amounts of tool oil into an air system to reduce friction in moving components. It is essential for air tools, cylinders, valves, air motors, and other air-driven equipment as lubrication extends their lifespan.

2. What are the different types of air lubricators?

There are two types of air lubricators: oil fog and micro fog. Oil fog lubricators deliver controlled lubrication to internal moving parts, while micro fog lubricators provide the best atomized mist for improved performance and reduced maintenance.

3. What kind of oil do you use for an air lubricator?

For an air lubricator, it is recommended to use ISO-VG32 or any lubricant specifically designed for pneumatic air tools. The oil flow can be adjusted by using the adjustment screw on top of the lubricator.

4. Do I need a lubricator on my air compressor?

Yes, lubrication is necessary for air compressors with piston or rotary components. These parts require smooth and consistent movement, which is achieved through proper lubrication.

5. Do I need an Oiler for air tools?

Yes, most air tools require lubrication to ensure optimal performance. Air tool oil is recommended for regular maintenance. Some tools may require daily lubrication, while others may have a grease fitting.

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

The two common lubrication systems for piston compressors are splash lubrication and pressure lubrication.

7. Can you use WD40 as air tool oil?

No, WD40 is not a suitable substitute for air tool oil. Pneumatic tools require oil specifically designed for their lubrication.

8. Can you use baby oil as a lubricator?

No, baby oil is not suitable as a lubricant for air systems. While it is safe for skin moisturization, it should not be used as a substitute for specialized lubricants. Baby oil can cause condom problems and skin irritation.
