Popular Questions

What is Air Force?

Air Force® is Liberty Systems’ line of high-pressure, clean dry air generation systems designed to provide a continuous, reliable supply of compressed air for demanding industrial applications.

Air Force® systems remove moisture, oil, and particulate contamination from compressed air while boosting it to the pressure required by your equipment. The result is a dependable source of clean, dry air that helps protect sensitive machinery, improve process performance, and reduce maintenance costs.

Air Force systems offer:

  • High-pressure clean, dry air delivered on demand.
  • Low pressure dew points to protect equipment from moisture and corrosion.
  • Multi-stage filtration to remove oil, water, and particulate contamination.
  • Reduced downtime and maintenance by supplying consistent, high-quality compressed air.
  • Seamless integration with Liberty Systems’ Nitro Force® nitrogen generators or existing compressed air systems.

Air Force® is ideal for laser cutting, manufacturing, pneumatic equipment, and other industrial processes that require clean, dry, high-pressure compressed air for reliable operation.

What does my warranty cover?

Liberty Systems backs every system with one of the strongest warranties in the industry. Every system includes a standard warranty covering defects in materials and workmanship, with extended 2- and 3-year options available on select series. Coverage depends on series and routine preventive maintenance. Your Sales Engineer can confirm what applies to yours.

What is FilterStar?

FilterStar encompasses our service agreements and courtesy maintenance reminders. If you choose to perform preventive maintenance on your own, or you prefer to order service parts as needed, Liberty systems will send a courtesy message to you, reminding you of the items needed and when equipment service is due.

Will Liberty Systems ship the orders (freight-shipping arrangements)?

You keep full control over routing and cost. Liberty Systems provides everything needed to book the load: weights, dimensions, piece count, and handling requirements.

What happens if the product I received is damaged?

We will assess the damage, if it is cosmetic, we will put the system into operation and make any necessary repairs at the soonest date possible.

Can I install black iron pipe to interconnect the system components or to supply nitrogen gas or clean dry air to my application?

No. Consult with your Liberty Sales Engineer for more detail.

How do I buy an Air Force® High Performance Air system?

Please contact Liberty Systems and a Sales Engineer will help guide you through the process.
