A precision filter is a highly efficient filtration device used to remove impurities such as tiny particles, oil mist, and moisture from compressed air or gas. It typically uses a multi-layer filter element structure with a filtration accuracy of up to 0.01μm, ensuring that the gas cleanliness meets industrial standards (such as ISO 8573-1).
Product features
✅ High-efficiency filtration: Removes oil mist, dust, microorganisms, and other components, purifying compressed air.
✅ Multiple filter stages available: Covers diverse needs, including coarse filtration (1μm), fine filtration (0.01μm), and activated carbon adsorption.
✅ Low maintenance: Easy filter element replacement, minimal pressure drop, and energy savings.
✅ Extends equipment life: Protects downstream precision instruments and pneumatic components.

Applications
• Food & Pharmaceuticals: Sterile compressed air (to prevent contamination)
• Electronics & Semiconductors: Chip manufacturing, precision assembly
• Spraying & Painting: Preventing particle contamination on paint surfaces
• Pneumatic Tools & Automation: Reducing equipment wear
• Laboratory & Testing Equipment: High-purity gas supply
FAQ
Q1: How do I choose a filtration accuracy?
A: Standard pneumatic tools (1μm), precision instruments (0.01μm), sterility requirements (with activated carbon layer).
Q2: How often should the filter element be replaced?
A: Typically 3-12 months (depending on the contaminant content, replacement is required when the pressure differential is ≥ 0.7 bar).
Q3: Can it remove oil and water?
A: It must be used in conjunction with a dryer. Precision filters primarily remove particles and oil mist, and some models can absorb trace amounts of oil.
Q4: Are there any installation location requirements?
A: Generally, it should be located downstream of the dryer, close to the gas point of use for best results.
Q5: Will it affect the air pressure?
A: A high-quality filter element has a pressure drop of ≤ 0.2 bar. If it becomes clogged, the pressure drop increases and needs to be replaced promptly.
