Air Filters Fully Auto Drain

Automatic Drain Inline Air Filters for Compressed Air Systems

The Pneuforce XOF Series automatic drain air filters are designed to remove water, dirt, rust particles and contaminants from compressed air systems while automatically discharging accumulated condensate. Ideal for industrial automation, packaging machinery, machine tools and manufacturing equipment, these filters help maintain clean compressed air while reducing routine maintenance requirements.

Featuring a fully automatic condensate drain system, the XOF Series eliminates the need for manual bowl draining, helping prevent moisture carryover and improving pneumatic system reliability. Built around a modular compressed air preparation platform, these filters can be used independently or assembled with regulators and lubricators to create a complete FRL (Filter-Regulator-Lubricator) system.

Key Features

• Fully automatic condensate drain system
• Modular FRL platform design
• Quick-release bowl assembly
• 40 micron standard filter element
• Optional 5 micron polyethylene filter element
• Suitable for standalone or modular FRL installations
• Reduced maintenance requirements
• Compact industrial design

Why Use an Automatic Drain Air Filter?

Compressed air naturally contains moisture that condenses as air cools within the distribution system. If not removed, this condensate can damage pneumatic valves, regulators, cylinders and instrumentation while contributing to corrosion and contamination.

Automatic drain filters continuously remove collected moisture without operator intervention, helping maintain filtration efficiency and reducing maintenance requirements in busy production environments.

Benefits of Automatic Condensate Drains

• No manual bowl draining required
• Reduced maintenance labor
• Improved system reliability
• Prevents excessive condensate buildup
• Protects downstream pneumatic equipment
• Ideal for difficult-to-access installations

Modular FRL Assembly

The XOF Series can be combined directly with air pressure regulators and airline lubricators using FRL assembly kits. This modular design creates a compact compressed air preparation station that simplifies installation while providing filtration, pressure control and lubrication from a single assembly.

This style of modular air preparation system is widely used by machine builders and industrial automation companies throughout North America and Europe.
