RF-0511-CP
Alternative to 050-11-BQ
RF-0511-CP – Reliable 050-11-BQ Alternative (0.01 Micron Particulate Filtration)
The RF-0511-CP is a precision-engineered 050-11-BQ alternative for applications where corrosive or highly reactive gases (and compatible liquids) must be filtered with confidence. As a 100% compatible replacement, this element is designed to protect sensitive downstream components while maintaining stable performance under demanding chemical conditions.
Built for Corrosive Media: Microfibre Glass + PVDF (Kynar®) Bonding
When choosing a 050-11-BQ replacement filter, chemical resistance and adsorption behavior are often the deciding factors. The RF-0511-CP uses a microfibre glass filtration media bonded with Kynar® fluorocarbon (PVDF) resin, providing:
- Excellent chemical resistance for aggressive process environments
- Very low adsorption, ideal for reactive gas service where purity matters
- Wide temperature capability from -50°C to +150°C
High Efficiency at 0.01 Micron
The RF-0511-CP delivers 99.99% efficiency at 0.01 micron particles, making it a strong choice when you need a high-performing particulate element—not just a “fit”, but a true functional equivalent.
With air flow resistance < 6 kPa at 6 m/min (25°C), it supports efficient operation and helps keep pressure drop within predictable limits.
Dimensions and Mechanical Stability (Direct Fit)
Designed for seamless installation, the RF-0511-CP matches the required form factor:
- Inner diameter: 12.5 mm
- Outer diameter: 17 mm
- Length: 57 mm
- Burst minimum: 0.8 bar
- Collapse minimum: 1.2 bar
