FRC Filter Regulator Lubricator User Manual
Product Overview
The WENK Festo-type FRC Filter Regulator Lubricator is a premium pneumatic two-unit combination integrating filter regulator and lubricator functions. Featuring high-precision filtration (5μm), precise pressure regulation (0.05-0.85MPa), and adjustable oil mist lubrication, it delivers clean, stable, and lubricated air for pneumatic systems.
Technical Specifications:
- Composition: Filter Regulator (5μm) + Lubricator
- Operating Pressure: 0.1-1.0MPa
- Pressure Regulation Range: 0.05-0.85MPa
- Operating Temperature: 5-60°C
- Water Cup Capacity: Depending on model
- Oil Cup Capacity: Depending on model
- Recommended Oil: ISO VG32 turbine oil
- Features: Modular design, manual drain, transparent bowls for visibility, high-precision filtration
Installation Steps
1. Pre-installation Preparation
- Ensure the compressed air system is shut off and depressurized
- Clean connecting pipes to remove foreign matter and impurities
- Prepare necessary tools: wrench, thread seal tape, etc.
- Check the unit for any damage or defects
2. Installation Sequence and Direction
- Strictly follow the air flow direction: Filter Regulator → Lubricator
- Connect pipes according to the arrow indicators on the unit
- Connect the inlet port to the upstream air source and the outlet port to downstream equipment
3. Pipe Connection
- Use thread seal tape on threaded connections to ensure proper sealing
- Tighten connections evenly with a wrench, avoiding excessive force that may damage threads
- Ensure all connections are secure and tight
4. Mounting and Fixing
- Use the dedicated mounting bracket, matching the convex groove with the body's concave groove
- Secure with fixing plates and screws
- Ensure vertical installation with drain valves and oil cups facing downward
5. Post-installation Check
- Ensure all connections are secure and free from looseness
- Verify that the unit is installed vertically
- Confirm that the air flow direction matches the arrow indicators
Operation Guide
1. Startup Procedure
- Slowly open the upstream air source valve to gradually increase pressure
- Check for any leakage in all components
- Inspect transparent bowls for cracks or damage
2. Filter Regulator Operation
-
Pressure Adjustment:
- Pull up the pressure adjustment knob, turn clockwise to increase pressure, counterclockwise to decrease
- After adjusting to the desired pressure, push down the knob to lock in position
- Adjust pressure gradually and evenly to the required value, avoiding one-step adjustment
- Monitor output pressure through the pressure gauge
-
Drainage Operation:
- Rotate the drain knob at the bottom of the bowl clockwise to open the drain valve
- After draining, rotate the knob counterclockwise to close the valve
- Daily inspection of drainage is recommended, with increased frequency in high-humidity environments
3. Lubricator Operation
-
Oil Filling:
- Use ISO VG32 turbine oil or equivalent
- Remove the oil cup or filler plug, fill to 80% capacity
- Reinstall the oil cup or filler plug, ensuring proper sealing
-
Oil Flow Adjustment:
- Rotate the adjustment knob on top of the lubricator to adjust oil mist concentration
- Number 0 represents minimum oil flow, 9 represents maximum
- Cannot rotate from 9 to 0 directly; must rotate clockwise
- Recommended setting: 4-8 drops per minute
Maintenance
1. Daily Inspection
- Regularly check transparent bowls to observe condensed water level and oil level
- Inspect all components for leakage
- Check connecting pipes for damage
- Regularly verify pressure gauge readings
- Check lubricator oil drop rate
2. Filter Maintenance
-
Filter Element Replacement:
- Replace when the element appears visibly dirty or when outlet air volume decreases significantly
- Replacement steps:
- Shut off air supply and relieve pressure
- Unscrew the filter bowl and remove the old element
- Clean the inner wall of the bowl
- Install the new element, ensuring proper sealing
- Reinstall the bowl securely
3. Lubricator Maintenance
- Oil Refill: Refill when oil level drops below 1/4 of the cup capacity
- Cleaning: Periodically clean the oil cup and suction tube to prevent clogging
4. Maintenance Schedule
- Filter element replacement: Generally every 3-6 months, depending on usage environment
- Lubricator oil refill: Check weekly based on oil level observation
- Drainage operation: At least once daily
- Pressure calibration: Every 3 months
Precautions
1. Safety Precautions
- Always shut off air supply and relieve pressure before installation and maintenance
- Do not exceed the maximum operating pressure of 1.0MPa
- Avoid use in high-temperature environments (temperature not exceeding 60°C)
- Do not strike transparent bowls with sharp objects
2. Usage Limitations
- For compressed air systems only
- Not suitable for corrosive gas environments
- Avoid direct sunlight and strong vibrations
- Some parts are made of PC material; keep away from organic solvents
3. Oil Selection
- Must use ISO VG32 turbine oil or equivalent
- Do not use gear oil, engine oil, or other types of oil
- Oil should be clean and free from impurities
4. Troubleshooting
- Filter clogging: Replace the filter element
- Pressure regulation failure: Check if the pressure spring is damaged, replace if necessary
- Lubricator not dripping oil: Check if oil level is too low or if the suction tube is clogged
- Leakage: Check connections for tightness, replace seals if necessary
Frequently Asked Questions
Q1: What is the correct installation sequence for the unit?
A1: Must be installed in the order of Filter Regulator → Lubricator, strictly following the air flow direction.
Q2: How to determine if the filter element needs replacement?
A2: Replace when the element appears visibly dirty, when outlet air volume decreases significantly, or when pressure drop increases.
Q3: What type of oil should be used in the lubricator? What oil level should be maintained?
A3: ISO VG32 turbine oil should be used. The oil level should be maintained between 1/4 and 8/10 of the cup capacity, with the optimal level being 80%.
Q4: What should be noted during pressure adjustment?
A4: Adjust pressure gradually and evenly to the required value, avoiding one-step adjustment. Be sure to push down the knob to lock in position after adjustment.
Q5: How to handle leakage in the unit?
A5: Check all connections for looseness and inspect seals for damage. Retighten or replace seals as necessary.
