Anping County Boli Hardware Wiremesh Products Factory, established in 1998, brings over two decades of manufacturing expertise to the B2B market with our MFK-032-39.4 Oil Mist Filter. This high-performance filter is specifically engineered for CNC machine tools, compressed air systems, and pneumatic equipment protection. Our factory, located in Hengshui, Hebei, China, annually exports US$5-10 million worth of precision filtration solutions to global markets including North America, Europe, and Southeast Asia. The MFK-032-39.4 combines rugged construction with advanced filtration technology to effectively remove oil mist and particulate contaminants, ensuring reliable operation of downstream pneumatic components.
The filter utilizes a multi-stage filtration design: first, a coarse stainless steel mesh captures larger particles; then, a fine coalescing element removes oil aerosols down to 0.3 microns. This process protects valves, cylinders, and actuators from oil contamination, extending equipment life by up to 30%. The unit features a transparent polycarbonate bowl for easy visual inspection of collected oil, with a manual drain valve for quick maintenance. All metal parts are corrosion-resistant aluminum alloy or stainless steel, suitable for harsh workshop environments.

Product Features and Benefits:
- High-Efficiency Oil Mist Removal: The coalescing element separates oil particles as small as 0.3 microns, achieving 99.5% removal efficiency. This significantly reduces oil carryover into pneumatic systems, preventing valve stiction and cylinder wear.
- Durable Construction: Housing is made from die-cast aluminum alloy with a powder-coated finish for corrosion resistance. The stainless steel mesh pre-filter extends the life of the main element.
- Easy Maintenance: The transparent bowl allows quick visual inspection of oil level. Manual drain valve enables simple purge without tools. The filter element is replaceable, reducing long-term cost.
- Compact Design: With dimensions of 100mm x 80mm (H x D), the MFK-032-39.4 fits easily into tight spaces on CNC machines or pneumatic panels. The universal mounting bracket supports wall or bracket installation.
- Wide Compatibility: Works with most compressed air systems operating at 0.1-1.0 MPa. Suitable for lubricated and non-lubricated lines. Optional accessories include automatic drain and pressure gauge.
- Energy Savings: By removing oil mist, the filter reduces downstream pressure drop and improves system efficiency. Lower maintenance frequency means less downtime for production lines.
Trusted by Global Manufacturers: Since 1998, Anping County Boli Hardware Wiremesh Products Factory has supplied filtration solutions to customers in over 15 regional markets. Our annual export volume of US$5-10 million demonstrates consistent quality and reliability. Each MFK-032-39.4 filter undergoes strict quality control: pressure testing at 1.5 times working pressure, and 100% flow and filtration efficiency inspection before shipment.

Frequently Asked Questions (FAQ):
-
Q: What is the filtration efficiency of the MFK-032-39.4?
A: It removes 99.5% of oil mist particles down to 0.3 microns, effectively protecting pneumatic components from oil contamination. -
Q: Can I use this filter for water separation?
A: This model is primarily designed for oil mist removal. For water separation, we recommend using a water separator in series. Contact our sales for combination solutions. -
Q: How often should I replace the filter element?
A: Replacement interval depends on oil concentration and operating hours. Typically change every 3-6 months, or when pressure drop exceeds 0.05 MPa across the filter. -
Q: Is the filter suitable for food-grade compressed air?
A: The standard version uses polycarbonate bowl and aluminum housing. For food-grade applications, optional stainless steel and special seals are available. Please specify when ordering. -
Q: What is the maximum working pressure?
A: 1.0 MPa (145 psi). Do not exceed this pressure to avoid damage. For higher pressure systems, ask about our HP series. -
Q: Does the filter come with mounting brackets?
A: Yes, a universal mounting bracket is included. It can be mounted vertically or horizontally. For special mounting, please consult our technical team. -
Q: What is the warranty period?
A: We offer a 12-month warranty against manufacturing defects. The filter element is considered a consumable part and is not covered under warranty. -
Q: Can I get custom port sizes?
A: Yes, we offer customization for port sizes (1/8", 3/8", 1/2" BSPT or NPT) and bowl material (metal bowl with sight glass). Minimum order quantity may apply.
