G-Series GF Air Filter User Manual
Product Overview
The WENK G-Series GF Air Filter is a premium Airtac-type pneumatic component designed for compressed air purification. Featuring efficient filtration (standard 40μm, optional 5μm) and a unique diversion structure, it effectively removes moisture, oil mist, and solid particles from compressed air, providing clean air supply for pneumatic systems.
Technical Specifications:
- Working Medium: Compressed air
- Operating Pressure: 0.1-1.0MPa
- Proof Pressure: 1.5MPa
- Operating Temperature: -20-70°C
- Water Cup Capacity: 10-230cc (depending on model)
- Filtration Precision: Standard 40μm, optional 5μm (customized)
- Features: Unique diversion structure, multiple drainage options, transparent bowls for visibility, low pressure loss with high filtration efficiency
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 air filter for any damage or defects
2. Installation Direction
- Strictly follow the air flow direction: Inlet → Filter → 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 filter 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. 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
3. Filter Element Condition Check
- Observe the filter element condition through the transparent bowl
- Replace the element when it appears visibly dirty or when outlet air volume decreases significantly
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
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)
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
- Poor drainage: Check if the drain valve is clogged, clean or replace if necessary
- Leakage: Check connections for tightness, replace seals if necessary
Frequently Asked Questions
Q1: What is the correct installation direction for the air filter?
A1: Must be installed in the order of Inlet → Filter → 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 drainage options are available?
A3: Three drainage options are available: manual drain, differential pressure drain, and automatic drain, which can be selected according to the usage environment.
Q4: How to handle leakage in the air filter?
A4: Check all connections for looseness and inspect seals for damage. Retighten or replace seals as necessary.
Q5: What is the operating pressure range of the filter?
A5: The operating pressure range is 0.1-1.0MPa; do not exceed the maximum operating pressure.
