Ultimate cost performance, stable flow, and flexible configuration — the Airtac series air preparation units offer a compelling choice in the mid-to-high-end market. With a streamlined design and flexible options, they deliver reliable performance while meeting diverse industrial needs at lower cost. Fokca’s Airtac series units are made from aluminum alloy with high-quality POM/PC components, manufactured through fully automated precision machining for consistent quality. The A series features a compact design with smaller ports and no protective cover, ideal for confined spaces. The B series is larger, with a PA protective cover, suitable for medium to high flow applications. Multiple options are available, including filtration accuracy, drain type, port size, and accessories, ensuring flexibility for various applications.
The Airtac series air preparation unit typically consists of an air filter, pressure regulator, and lubricator (FRL). Its function is to treat compressed air from the air compressor through three stages: filtration to remove impurities and moisture, pressure regulation for stable output, and lubrication for precise oil mist delivery. This ensures a clean, stable, and lubricated air supply for downstream components such as cylinders, valves, and pneumatic tools—extending equipment life, improving operational stability, and enhancing product quality.
Fokca’s Airtac series air preparation units are known for their cost-effectiveness, practicality, and wide application. The product range includes AC/BC series FRL units, AFC/BFC series filter-regulator units, AFR/BFR series filter regulators, AF/BF series filters, AR/BR series regulators, and AL/BL series lubricators—providing reliable and economical air supply solutions for automation systems.

Cost-effective and highly versatile—the Airtac series is a reliable all-purpose air treatment solution for applications below 1.0 MPa. It meets most industrial needs while maintaining stable performance at a competitive price.
Fokca units are made from aluminum alloy with high-quality plastic components and manufactured through fully automated precision machining for consistent quality.
· A Series: Compact, smaller ports, no protective cover—ideal for tight spaces and small equipment
· B Series: Larger size with protective cover—suited for medium to high flow and enhanced protection
Most models use HDPE filter elements, offering high efficiency, large dirt-holding capacity, and durability. Multiple options are available for filtration accuracy, drain type, and pressure range.
Step 1: Define Function Requirements
| Requirement | Recommended Product |
|---|---|
| Filtration only | AF/BF Series Filter |
| Pressure regulation only | AR/BR Series Regulator |
| Lubrication only | AL/BL Series Lubricator |
| Filtration + Regulation | AFR/BFR Series |
| Full treatment (space available) | AC/BC Series FRL |
| Full treatment (limited space) | AFC/BFC Series |
Step 2: Select Series Size
· A series: Compact, for small equipment and limited space
· B series: Larger, for higher flow and added protection
Step 3: Choose Port Size
· G1/8" ~ G1/4": Small equipment, single machines, end actuators
· G3/8" ~ G1/2": Medium production lines, multi-cylinder systems
Step 4: Confirm Thread Type
· BSPP (G): Parallel thread, general standard
· BSPT (R): Tapered thread
· NPT: American tapered thread
Step 5: Select Filtration Accuracy
· 40μm: General use, low pressure drop
· 5μm: Precision components (pilot valves, sensors, injectors)
Step 6: Choose Drain Type
· Manual drain: Cost-effective, requires regular inspection
· Differential pressure drain: Ideal for systems with daily shutdowns
· Float auto drain: Suitable for continuous 24/7 unattended operation
