RF-0511-BSI

RF-0511-BSI – High-Temperature 050-11-AH Alternative with Inorganic Silica Bonding

When standard filter elements reach their limits, the RF-0511-BSI steps in. As a fully compatible 050-11-AH alternative, this particulate filter element is engineered for extreme temperature applications where organic binders would fail. If your process runs hot, this is the element you need.

Completely Inorganic – A Different Class of Filter

Unlike PVDF-bonded elements, the RF-0511-BSI uses silica inorganic resin exclusively. No organic components, no thermal degradation risk. This makes it a fundamentally different – and superior – 050-11-AH replacement filter for high-temperature service:

• Fully inorganic construction – no organic binders that could off-gas or degrade
• Temperature resistance from -50°C up to +500°C – far beyond what standard particulate elements can handle
• Ideal for high-temperature gas lines, furnace atmospheres, and thermally demanding analytical systems

Typical applications include:

• High-temperature gas sampling and analysis
• Instrument protection in hot process environments
• Specialty gas lines operating above 150°C
• Industrial furnace or combustion gas filtration

Exceptional Filtration Efficiency

The RF-0511-BSI delivers an outstanding 99.9999% efficiency at 0.01 micron – the highest grade in the 050-11 replacement series. Combined with a low air flow resistance of < 2.8 kPa at 6 m/min (25°C), it provides maximum particle retention with minimal impact on system pressure.

Dimensional Compatibility – Direct Drop-In Replacement

The RF-0511-BSI is a direct-fit 050-11-AH alternative with identical dimensions to the original:

• Inner diameter: 12.5 mm
• Outer diameter: 17 mm
• Length: 57 mm
• Burst minimum: 0.8 bar
• Collapse minimum: 1.2 bar
