Festo PFAN-3X0,5-NT Pneumatic Tubing

Technical Overview

The Festo PFAN-3X0,5-NT (part number 8061167) is a high-performance industrial polymer tube designed for demanding fluid control environments. Engineered with a 3mm outside diameter and 2.3mm inside diameter, it offers exceptional thermal stability with an operating temperature range spanning from -20°C to 150°C. The tubing is highly resilient, capable of handling temperature-dependent operating pressures from vacuum (-0.95 bar) up to 15 bar. Approved by TÜV and resistant to chemicals, it is versatile enough to reliably transport compressed air (ISO 8573-1:2010), water, and water vapor, making it suitable for food processing, sterilization routing, and heavy-duty industrial automation applications.

Industrial Applications

1. High-Temperature Automation Cells

Utilized for pneumatic actuations in high-heat environments like plastic injection molding setups or drying kilns.

Problem Solved

Standard polyurethane tubes melt or degrade at high heat. This polymer tubing maintains structural integrity and operational pressure even when ambient temperatures reach 150°C.

2. Compact Vacuum Pick-and-Place

Serves as the vacuum line routing (-0.95 bar) for miniature suction cups in tight Cartesian robots and semiconductor handlers.

Problem Solved

The ultra-small 3mm OD and aggressive 10mm minimum bending radius prevent kinking in micro-cable chains, while efficiently holding full vacuum pressure without collapsing.

3. Food Packaging Steam Sterilization

Routes low-pressure water vapor (up to 1.5 bar) for localized sterilization and washdown within food-grade packaging machines.

Problem Solved

Provides a chemically resilient, TÜV-approved passageway for vapor that won't break down during SIP (Sterilization-in-Place) procedures.
