Exceptional Filtration Capabilities
The Inline Air Compressor Filter is designed specifically to remove oil and water from compressed air systems. It operates effectively at pressures up to 150 PSI, ensuring that your air tools remain clean and efficient. By using this filter, you can prevent moisture from entering your air compressor, which can lead to rust and damage. This is crucial for maintaining the longevity of your equipment and enhancing the performance of your tools.
Innovative Auto Drain Feature
One significant advantage of the Inline Air Compressor Filter is its automatic drainage system. This feature automatically expels accumulated water without any manual intervention. Therefore, it saves you time and ensures that the filter operates optimally without clogging. Regular maintenance is reduced because the filter constantly drains excess moisture, allowing you to focus on your work instead.
Easy Installation and Maintenance
The Inline Air Compressor Filter is designed for easy installation, making it a practical choice for both professionals and DIY enthusiasts. It connects seamlessly into your existing air compressor system, ensuring minimal downtime. Maintenance is straightforward; check filters regularly and replace them as needed to ensure consistent air quality. Because of its user-friendly design, you can maintain your air compressor system without a hassle.
Frequently Asked Questions
Q: How often should I drain the water separator?
A: Drain the ZN312 before each use session and during extended operation in humid conditions. The transparent bowl lets you visually monitor moisture accumulation. In high-humidity environments, you may need to drain every 1-2 hours of continuous use.
Q: What's the difference between the ZN312 and the ZN312E-3?
A: The ZN312 is a standard inline filter with oil/water separation and auto drain. The ZN312E-3 adds a desiccant filter stage that absorbs moisture vapor — providing much drier air than mechanical separation alone. Choose the ZN312E-3 for spray painting and moisture-sensitive applications.
Q: Can I install multiple filters in series?
A: Yes, installing filters in series improves air quality progressively. A common setup is: ZN312 first (removes bulk water and large particles), followed by a desiccant dryer (ZN312E-3 or ZN312-D-C1) for ultra-dry air. This two-stage approach extends desiccant life significantly.

What is the difference between the ZN312 and AI303?
Both are 1/4" NPT inline filters at 150 PSI. The ZN312 features automatic draining and is designed for set-and-forget installation. The AI303 has manual drain and is slightly more compact. Choose the ZN312 for permanent installation; choose the AI303 for portable or temporary setups.
How effective is the auto-drain feature?
The auto-drain activates when accumulated water reaches a threshold level. It works well for continuous-use environments. In light-use shops, you may still want to manually check periodically, especially in humid conditions.
Is this the same as an air compressor moisture trap?
Yes, the ZN312 functions as both a moisture trap and oil separator for air compressors. It traps condensed water (moisture) and oil mist from your compressed air line before they reach your tools. The auto-drain feature means trapped moisture is released automatically, unlike basic moisture traps that require manual draining.
