Pneumatic Tube

Festo Pneumatic Tubing

1. PUN-H Series (Polyurethane Tubing)

The PUN-H is the most versatile and popular tubing in the Festo lineup. It is highly flexible and resistant to hydrolysis (moisture damage).

1. Key Features: Kink-resistant with a small bending radius; food-safe and resistant to microbes.
2. Applications: Standard industrial automation, food packaging, and wet environments.
3. Benefit: Its transparency allows for easy visual inspection of the air or fluid flow, and it is compatible with a wide range of push-in fittings.

2. PAN Series (Polyamide/Nylon Tubing)

For applications involving higher temperatures or higher pressures, the PAN series is the go-to choice.

1. Key Features: High thermal and mechanical resistance; excellent pressure rating even at elevated temperatures.
2. Applications: Compressed air systems, pneumatic brake lines, and heavy-duty machinery.
3. Benefit: Polyamide construction ensures the tube remains dimensionally stable under pressure, preventing "ballooning" or air leaks at connection points.

3. PEN Series (Polyethylene Tubing)

An economical solution for standard pneumatic applications that require chemical resistance.

1. Key Features: High resistance to common industrial cleaning agents and chemicals.
2. Applications: Simple pneumatic control systems and basic material handling.
3. Benefit: Provides a cost-effective alternative for systems where extreme flexibility is not as critical as chemical durability.

4. PFAN Series (Fluoropolymer Tubing)

Designed for the most extreme conditions, the PFAN series can withstand high heat and aggressive chemical environments.

1. Key Features: Operating temperature range from -20°C to +150°C; flame-retardant and highly resistant to UV and chemicals.
2. Applications: Chemical processing, pharmaceutical labs, and automotive engine compartments.
3. Benefit: The "non-stick" surface prevents deposits from building up inside the tube, ensuring consistent air pressure over time.
