Fokca Air Filter Regulator Lubricator integrate a filter-regulator with a lubricator, delivering the three core functions of filtration, pressure regulation, and lubrication in a more compact structure. This integrated design reduces overall length by 30%-40% and minimizes connection points to lower leakage risks. Available in options such as SMC AC series FRL combinations and Airtac AFC/BFC series, they are the ideal choice for control cabinet installation, small equipment integration, and OEM applications.
A Air Filter Regulator Lubricator (2-piece) is an air treatment assembly consisting of two main modules: a filter regulator (an integrated unit combining a filter and pressure regulator) and a lubricator. It performs the same functions as a three-unit FRL—providing clean, stable, and lubricated compressed air to downstream cylinders, valves, and pneumatic tools—but achieves a more streamlined piping layout by integrating filtration and pressure regulation into a single unit.
◆ Flexible Filter Media & Precision Options:
Offers sintered bronze filter elements (high strength, reusable after cleaning) and fiber filter elements (high filtration efficiency and large dirt-holding capacity). Standard filtration ratings of 5μm/40μm are available, with customization options to meet various cleanliness requirements.
◆ Multiple Drainage Options:
Manual, differential-pressure semi-automatic, and float-type fully automatic drainage options are available to suit different operating conditions.
◆ One-Stop Full Brand Coverage:
Covers mainstream brands such as SMC, FESTO, and Airtac, enabling fast selection and guaranteed authenticity.
• FESTO OU Series:
High pressure resistance, smooth and precise pressure adjustment, and an aesthetically pleasing design.
• SMC AC Series:
Large flow capacity, wide application range, precise and sensitive pressure regulation, with a locking mechanism to prevent accidental adjustment.
• Airtac AFC/BFC Series:
Integrated zinc/aluminum alloy body, available in white plastic coating or natural finish, featuring a clean and simple appearance.
◆ Integrated Design, Space Saving:
By combining filtration and pressure regulation into a single valve body, the overall length is reduced by 30%–40% compared to separate filter and regulator combinations. This is especially important for space-constrained applications such as control cabinets, compact equipment, and robotic end-effectors.
| Comparison Aspect | 2-piece (FR + L) | 3-piece (F + R + L) |
|---|---|---|
| Structure | Filter regulator (integrated) + lubricator | Separate filter, regulator, and lubricator |
| Space Requirement | Compact, 30%–40% shorter | Longer, requires more installation space |
| Maintenance | Replace filter-regulator module as a whole | Each component can be replaced individually |
| Leakage Risk | Lower (fewer connection points) | Higher (more connection points) |
| Applications | Space-limited setups, control cabinets, OEM equipment | Large production lines, flexible maintenance requirements |
| Cost Structure | Slightly higher initial cost, lower installation cost | Lower initial cost, higher piping and installation cost |
Q1: Can a 2-piece FRL unit fully replace a 3-piece unit?
A1: Functionally, yes. A 2-piece FRL unit provides filtration, pressure regulation, and lubrication just like a three-unit, with equivalent performance in filtration accuracy, pressure stability, and lubrication effect. The only difference lies in the physical structure: the 2-piece unit integrates filtration and regulation, while the three-unit consists of three separate components.
Q2: What if the filter regulator in a 2-piece FRL unit fails? Does it need to be replaced ?
A2: Yes. Since filtration and regulation are integrated into a single valve body, failure of either function typically requires replacement of the entire filter-regulator module. However, fokca.com maintains sufficient stock for all product lines, ensuring fast replacement and minimizing downtime. If your application requires independent replacement of components, a three-unit is recommended.
Q3: Is the 2-Piece FRL unit suitable for oil-free pneumatic systems?
A3: Yes. Simply remove the lubricator module. The essence of a 2-piece unit is the combination of a filter regulator and a lubricator. If lubrication is not required (e.g., when using oil-free cylinders), you can directly use the filter regulator (FR unit) alone without purchasing the complete 2-piece unit set.
