- Operating Temperature: -20-70°C
- Water Cup Capacity: 10-80cc (depending on model)
- Filtration Precision: Standard 40μm, optional 5μm (customized)
- Features: Embedded pressure gauge, multiple drainage options, transparent bowls for visibility, balanced pressure regulation mechanism
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 filter regulator for any damage or defects
2. Installation Direction
- Strictly follow the air flow direction: Inlet → Filter → Regulator → Outlet
- 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 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. Pressure Adjustment 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
3. Drainage Operation
- Automatic Drain: Drains automatically when water level reaches set value
- Differential Pressure Drain: Drains automatically when pressure difference reaches set value
- Manual Drain: 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
Maintenance
1. Daily Inspection
- Regularly check transparent bowls to observe condensed water level and filter element condition
- Inspect all components for leakage
- Check connecting pipes for damage
- Regularly verify pressure gauge readings
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. Maintenance Schedule
- Filter element replacement: Generally every 3-6 months, depending on usage environment
- Drainage operation: At least once daily (except for automatic drain models)
- 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 70°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. Troubleshooting
- Filter clogging: Replace the filter element
- Pressure regulation failure: Check if the pressure spring is damaged, replace if necessary
- Leakage: Check connections for tightness, replace seals if necessary
Frequently Asked Questions
Q1: What is the correct installation direction for the filter regulator?
A1: Must be installed in the order of Inlet → Filter → Regulator → Outlet, 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 should be noted during pressure adjustment?
A3: 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.
Q4: How to handle leakage in the filter regulator?
A4: Check all connections for looseness and inspect seals for damage. Retighten or replace seals as necessary.
Q5: What drainage options are available?
A5: Three drainage options are available: manual drain, differential pressure drain, and automatic drain, which can be selected according to the usage environment.
