RF-0505-ESI

RF-0505-ESI – High-Temperature 050-05-DH Alternative (Inorganic Silica-Bonded Particulate Element)

The RF-0505-ESI is a fully compatible 050-05-DH alternative designed for applications where elevated temperatures rule out conventional, organically bonded filter elements. Built as a dependable 050-05-DH replacement filter, it combines an inorganic construction with stable particulate filtration—ideal when process conditions demand thermal robustness and reliable system protection.

Completely Inorganic for Hot Gas Service

The RF-0505-ESI uses a microfibre glass filtration media bonded only with silica inorganic resin. This fully inorganic design is the key advantage when your application involves high temperatures or heat cycling:

• 100% inorganic bonding (silica resin only)
• Temperature resistance from -50°C up to +500°C
• Suitable for high-temperature gas lines, hot sampling points, and thermally stressed instrument protection

Typical use cases include:

• High-temperature gas sampling and conditioning
• Protection of downstream sensors and analyzers
• Hot process streams where organic binders may degrade
• Applications requiring a stable element during thermal cycling

Performance Profile: Low Pressure Drop, Stable Filtration

If you need a 050-05-DH replacement filter optimized for high-temperature environments, the RF-0505-ESI provides a predictable operating profile:

• Filtration efficiency: 95% @ 0.01 micron particles
• Air flow resistance: < 2.8 kPa at 6 m/min (air at 25°C)

This makes the element a practical choice where maintaining flow and minimizing pressure drop are priorities, while still providing fine particulate retention.

Direct-Fit Dimensions and Mechanical Strength

The RF-0505-ESI is manufactured to match the required form factor for the 050-05 series:

• Inner diameter: 12.5 mm
• Outer diameter: 17 mm
• Length: 32 mm
• Burst minimum: 0.8 bar
• Collapse minimum: 1.2 bar

Cross Reference Coverage – 050-05 Series

This 050-05-DH alternative is part of a cross-reference family covering common 050‑05 variants, including:
