In industrial production, vacuum pumps serve as core equipment in semiconductors, heat treatment, new energy, and other fields. Their operational stability directly determines production efficiency and product quality. As the “protective barrier” and “purification core” of vacuum pumps, oil mist filters and exhaust filters are not only key components ensuring long-term equipment operation but also play an irreplaceable role in environmental compliance and cost control.
I. Core Value of Vacuum Pump Filters: More Than Spare Parts, But Equipment “Guardians”
The importance of vacuum pump filters goes far beyond ordinary consumables, with their performance directly impacting equipment lifespan and production benefits:
（1）Block contaminants and reduce failure risks: Efficiently filter solid particles (such as dust and metal shavings) in intake air and oil mist molecules in exhaust gas, preventing wear and clogging of precision components like pump chambers, vanes, and rotors, and reducing equipment failures by over 37%.
（2）Extend equipment lifespan and lower maintenance costs: High-quality filters can prolong the service life of core vacuum pump components by 2-5 times, and extend the pump oil replacement cycle from 6-8 weeks to 6-8 months, significantly reducing downtime for maintenance and consumable expenses.
（3）Ensure environmental compliance and purify the workplace: Oil mist filters achieve over 99.99% oil mist separation efficiency, with residual oil content in gas as low as 0.01mg/m³, meeting environmental emission requirements and protecting operators’ health.
（4）Maintain vacuum performance and improve product yield: Stable filtration keeps the vacuum pump’s pumping speed at over 95% of the nominal value, avoiding vacuum fluctuations that affect process precision and reducing workpiece rework rates.
II. Top Global Brands’ Bestselling Models + Main Filter Material Analysis
1. Key Characteristics of Main Filter Materials (Adapted to Different Working Conditions)
（1）Felt material: Filtration accuracy 0.01-10μm, high-temperature resistance up to 260℃, acid and alkali corrosion resistance, surface hydrophobic and non-dust-adhering, strong dust stripping ability, it is the mainstream choice for oil mist filter elements and exhaust filter elements, suitable for high-temperature, high-humidity and corrosive working conditions, with outstanding near-zero emission effect.
（2）Polymer Powder Sintered Material (fiberglass/PE/PP/PTFE): Processed from polymer powder (organic material such as polyethylene, polypropylene, or polytetrafluoroethylene) through temperature-controlled pressure sintering. It boasts high mechanical strength, good toughness, and impact resistance. Temperature resistance varies by material: PP up to 80℃, PTFE up to 260℃. Ideal for intake filters and oil mist filtration under harsh conditions, adapting to high-viscosity dust and continuous operation with long replacement cycles and low maintenance costs.
（1）Becker: 909510 (fits Rietschle 730545), 909529 (equivalent to Mann C78/6), 84040105 – adopting factory-customized glass fiber sintered material, tailor-made for its own vacuum pump models with perfect compatibility.
（2）Busch: 532025 (fits Becker 909514, Mann C718), 532015 (fits Mann C75/2) – glass fiber sintered material with PTFE coating, suitable for high-vacuum precision manufacturing scenarios.
（3）Rietschle: 731148 (fits Mann C612/1), 730354 (fits Mann C75/2) – using PP polymer powder sintered material, wear-resistant and anti-aging, ideal for heavy industrial applications.
