The AFR and BFR Series are the primary “Filter-Regulator” (FR) units designed for modern pneumatic systems. By integrating a centrifugal filter and a relief-style pressure regulator into one body, these units provide the two most critical air treatment functions—moisture removal and pressure stabilization—in a compact, cost-effective package.
As a leading B2B supplier of AFR and BFR units, Anruk Pneumatic ensures that every component meets the rigorous demands of industrial automation, offering a high-performance alternative to brand-name Airtac components.
Series Breakdown: AFR vs. BFR
Both series utilize the modular design architecture common in global automation, differing primarily by body frame size:
- AFR Series (Small/Mini): Features the AFR2000 (1/8″, 1/4″). These are the most common units for small-bore cylinders and localized pneumatic control valves.
- BFR Series (Medium/Large): Includes the BFR2000, BFR3000, and BFR4000 (1/4″, 3/8″, 1/2″). These units feature larger internal flow paths and increased bowl volume to handle higher CFM requirements without losing pressure stability.
Why Choose the Integrated FR Design?
Integrating the filter and regulator into a single unit (AFR/BFR) offers several technical and economic advantages for distributors and machine builders:
1. Dual-Function Efficiency
Instead of purchasing and plumbing a separate filter and a separate regulator, the AFR/BFR series handles both tasks. This reduces the number of leak points in your system and simplifies the Bill of Materials (BOM).
2. Space-Saving Footprint
The “stacked” design (regulator on top, filter bowl on bottom) is ideal for narrow installation spaces. It is the go-to choice for mounting on the side of machines or inside control cabinets where depth and width are limited.
3. Precision Pressure Control
Equipped with a balanced-valve design and a locking “press-to-lock” adjustment knob, these units provide excellent pressure stability even during fluctuations in the primary air supply.
Technical Specifications & Manufacturing Standards
At Anruk Pneumatic, we prioritize durability to ensure long-term reliability in harsh factory environments:
- Superior Filtration: Standard 40μm (micron) sintered brass or PE elements remove water, oil-water emulsions, and solid particles. 5μm elements are available for sensitive precision instruments.
- Pressure Range: Standard 0.05 ~ 1.0 MPa (7 ~ 145 PSI). High-pressure versions available upon request.
- Rugged Bowl Construction: Polycarbonate bowls with high transparency allow for easy visual checks, while the steel bowl guard protects against physical impact and chemical exposure.
- Drainage Flexibility:
- Manual/Semi-Auto Drain: Opens when pressure is released.
- Automatic Drain (AD): Essential for high-humidity environments where manual maintenance is difficult.
Strategic Advantage for Global B2B Buyers
- Direct OEM Compatibility: Our AFR and BFR units are built to standard Airtac dimensions. They can be used as direct replacements for original parts, making them perfect for the MRO (Maintenance, Repair, and Operations) market.
- Universal Threading: We supply units with G (BSP), NPT, and PT (Rc) porting to ensure compatibility with global plumbing standards.
- Cost Leadership: By sourcing from Anruk, you receive industrial-grade air preparation components at a fraction of the cost of premium brands, allowing for higher profit margins on your projects or distribution lines.
