Product details

1. Product Definition & Function

TheFRL Unit(Filter-Regulator-Lubricator) is a core pre-treatment device in pneumatic systems, integrating three functional modules:

• Filter: Removes moisture, oil contaminants, and solid particles (typical filtration精度: 5–40μm) from compressed air to prevent downstream component contamination.

• Regulator: Stabilizes output pressure (adjustable range: typically 0.5–10 bar) to meet the requirements of various pneumatic equipment.

• Lubricator: Injects atomized lubricating oil proportionally to extend the service life of actuators (e.g., cylinders, solenoid valves).

IMI NorgrenFRL units are renowned for high reliability, modular design, and low-temperature adaptability (select models), complying with international standards such as ISO/DIN.

2. Key Technical Specifications

【表格】

Parameter Typical Range Notes

Port Size 1/4" ~ 2" NPT/G Supports NPT (American tapered pipe thread) or G (British parallel thread).

Operating Pressure 0.1–16 bar (up to 25 bar for some models) Verify minimum startup temperature for low-temp models.

Filtration Rating 5μm / 25μm / 40μm Optional automatic drain valves available.

Pressure Regulation 0.5–10 bar (adjustable) Equipped with pressure gauges or digital displays (smart models).

Lubrication Rate 0.1–12 ml/8h (adjustable) Requires ISO VG32 pneumatic-specific oil.

Material Aluminum alloy (body) / Polycarbonate (bowl) Explosion-proof stainless steel options available.

Ambient Temperature -10°C to +60°C (standard) Low-temp models extend to -40°C (specify when ordering).

3. Modular Design Features

• Build-Block Assembly: Individual modules (F/R/L) can be disassembled for field replacement or upgrades.

• Mounting Options:

• Vertical Installation(recommended): Facilitates drainage and reduces oil mist deposition.

• Horizontal Installation: Requires drain valves for space-constrained applications.

• Accessory Options:

• Pressure Switches: Monitor output pressure and provide feedback signals.

• Soft-Start Valves: Prevent system shock during startup.

• Filter Blockage Alarms: LED indicators or electrical signal outputs.

------

4. Typical Applications

• Industrial Automation: Pneumatic grippers, cylinder-driven systems.

• Food & Beverage Packaging: Stainless steel filter modules for sterile environments.

• Cold Chain Logistics: Low-temp FRLs for refrigerated warehouse doors and conveyors (-40°C models).

• Energy Sector: Natural gas compression stations (ATEX-certified models).

------

5. Selection Guide

1. Flow Rate Matching: Select FRL port size based on the system’s maximum air consumption (e.g., 1000 L/min).

2. Pressure Rating: Confirm regulation range covers equipment requirements (e.g., 6 bar for cylinders).

3. Environmental Adaptability:

• High-humidity environments: Opt for automatic drain valves.

• Corrosive gases: Choose 316L stainless steel.

4. Certification Requirements: ATEX (explosion-proof), CE (EU), UL (North America), etc.

------

6. Maintenance & Troubleshooting

• Daily Checks:

• Drain valve blockage (manual drainage daily).

• Pressure gauge stability.

• Lubricator oil level (refill every 200 hours).

• Common Faults:

• Pressure Fluctuations: Check regulator spring or clogged filter.

• Insufficient Lubrication: Adjust oil flow or replace lubricator element.

• Air Leaks: Inspect seal degradation or loose threads.
