· •Clean the pump interface with a dry cloth to remove residual oil.

· •Align the new cartridge and rotate clockwise (or snap into place) until the seal is tight.

· •Test operation: Check pressure gauge (-0.06 ~ -0.08MPa) and noise levels to confirm proper installation.

​​2. Replacement Cycle​​

· •Light duty (≤8 hours/day): 6-8 months.

· •Standard duty (8-12 hours/day): 3-4 months.

· •Heavy duty (24/7 operation + high dust): 1-2 months.
Replace immediately if the cartridge turns dark brown or pump pressure exceeds -0.05MPa.

​​3. Maintenance Tips​​

· •Inspect O-rings monthly for cracks or deformation—replace as needed.

· •Avoid exposure to strong acids/bases or direct sunlight.

· •Handle with gloves to prevent oil contamination of the filter media.

​​（Q&A）​​

​​Q1: As a China manufacturer, what makes your oil mist filter cartridges different from others?​​
A: We combine German-imported glass fiber (superior filtration) with strict factory QC (ISO 9001 certified). Our cartridges offer 30% higher efficiency and 50% longer lifespan than generic market products.

​​Q2: Do you provide custom sizes or interfaces for GL3/GL6/GL9 models?​​
A: Yes. For special vacuum pump models (e.g., non-standard thread sizes), we offer custom adapter solutions. Contact us with your pump’s technical drawings for a quote.

​​Q3: Is the “99.9% filtration efficiency” tested independently?​​
A: Yes. Our filters are tested by SGS (third-party lab) using ISO 5011 standards, with reports available for download on our website.

​​Q4: How long can the cartridge last in high-temperature environments (e.g., foundries)?​​
A: Our standard cartridges withstand up to 150°C (180°C short-term). For continuous use above 180°C, we recommend our ceramic-coated upgrade model.

​​Q5: Can I replace the cartridge myself, or do I need a professional?​​
A: Our quick-connect design allows self-installation with basic tools (wrench). We provide video tutorials on our Alibaba store for guidance.

​​Q6: Are your products compliant with European/US environmental regulations?​​
A: Yes. Materials are RoHS-certified (no lead/heavy metals) and meet REACH standards. Filtered exhaust meets EU 2015/2193 (oil mist emission limits).

​​Q7: What is the lead time for bulk orders (e.g., 100+ units)?​​
A: Standard lead time is 15-20 days after order confirmation. For urgent requests, we offer expedited production (7-10 days) with a small surcharge.

​​Q8: Do you provide after-sales service for international clients?​​
A: Yes. We have a global service network and can arrange on-site technical support for large orders (e.g., 500+ units) at additional cost.

​​Q9: Why choose a China factory over local suppliers?​​
A: Our factory offers factory-direct pricing (15-30% lower than distributors), flexible MOQs (50 units minimum), and faster customization than overseas suppliers.

​​Q10: My cartridge arrived with a minor scratch—can I get a replacement?​​
A: Yes. Notify us within 24 hours of delivery with photos of the damage. We will send a free replacement and cover return shipping for defective products.
