In the world of industrial pneumatics, the AF and BF Series are the definitive “Airtac-type” standards for standalone air filtration. These units are engineered to extract liquid water, rust, and scale from compressed air lines, acting as a critical insurance policy for your downstream solenoid valves and cylinders.
As a dedicated B2B manufacturer and exporter, Anruk Pneumatic provides the AF and BF filter series as high-precision, cost-effective alternatives to original brand-name units, ensuring your automation systems run on clean, dry air.
Defining the Series: AF vs. BF
While both series utilize the same high-efficiency centrifugal filtration technology, they are divided by body size and flow capacity:
- AF Series (Compact to Medium): Includes models like the AF2000 (1/8″, 1/4″) and AF3000 (3/8″). These are optimized for localized filtration on small-to-medium machinery where space is a priority.
- BF Series (Large/High-Flow): Includes the BF2000, BF3000, and the heavy-duty BF4000 (1/2″). The BF series features a larger internal volume and filter element surface area to handle higher SCFM (Standard Cubic Feet per Minute) requirements without significant pressure drops.
Why AF & BF Series are the B2B Industry Standard
For global distributors and OEMs, these series offer a unique combination of modularity and ruggedness.
1. Universal 1:1 Interchangeability
Our AF and BF filters are manufactured to exact Airtac dimensional standards. This allows maintenance teams to perform “drop-in” replacements on existing equipment without re-piping or changing mounting brackets, significantly reducing labor costs.
2. Superior Water Separation
Using a high-speed internal vane design, these filters create a powerful centrifugal “cyclone.” This spins out up to 95% of liquid water and heavy particulates before the air even reaches the filter element, extending the life of the internal media.
3. Modular “Quick-Connect” Design
The AF/BF series is designed for modularity. Using standard spacers and brackets, these filters can be easily joined with AR/BR regulators or AL/BL lubricators to create a custom F.R.L. assembly tailored to specific machine requirements.
Technical Excellence: The Anruk Manufacturing Advantage
We focus on the structural details that ensure reliability in 24/7 factory environments:
- Sintered Filter Elements: Available in standard 40μm for general industrial use or 5μm for high-precision applications. Our elements are made from high-porosity sintered bronze or plastic that can be cleaned and reused.
- Safety-Lock Bowls: High-transparency polycarbonate bowls allow for easy monitoring of condensate levels. For safety, these are protected by a reinforced aluminum or steel guard to prevent damage from external impacts or pressure spikes.
- Advanced Drainage Options:
- Manual/Semi-Auto: Standard for most applications.
- Fully Automatic Drain: Highly recommended for large-scale facilities where manual maintenance is difficult; the drain opens automatically when water reaches a specific level.
- Die-Cast Aluminum Body: Unlike low-cost plastic alternatives, our AF/BF series features a robust metal body for superior thread strength and environmental resistance.
Strategic Value for Global Procurement
- Direct BOM Optimization: Reduce your procurement costs by 40% – 60% compared to traditional “Big Brand” pricing while maintaining the same performance metrics.
- Global Thread Standards: We supply these units in NPT, G (BSP), and PT (Rc) threads, ensuring total compatibility with North American, European, and Asian piping systems.
- OEM & Private Labeling: We offer custom branding and specialized filtration grades to help distributors build their own market identity.
