Core Advantages of Leybold Vacuum Pump Exhaust Oil Mist Filter

Superior Filtration Efficiency: Filtration efficiency＞99%. It effectively captures fine oil mist particles, reduces vacuum pump oil loss and refilling frequency to cut consumable costs.
Low Pressure Drop for Stable Operation: Initial pressure drop ＜10 kPa; stable operating pressure drop ＜30 kPa. No extra backpressure will be imposed on the vacuum pump, so ultimate vacuum level and pumping speed remain unaffected.
High‑Performance Material Combination for High‑Temperature & Corrosion ResistanceWide Working Condition Compatibility: Max operating temperature ＜110 °C, suitable for most continuous‑operation industrial vacuum pump scenarios.
- German‑made fiberglass filter paper: high filtration efficiency, outstanding corrosion resistance and stable differential pressure performance.
- PA66+GF30 end cap: high‑temperature resistant, high‑hardness, wear‑resistant and anti‑aging.
- Special PET surface filter media: excellent oil‑repellent, flame‑retardant and anti‑corrosion performance.
- FKM fluororubber sealing ring: great oil and heat resistance to prevent leakage.
- Stainless‑steel safety valve assembly: cracking pressure at 90±10 kPa. Automatic pressure relief occurs upon filter blockage to protect the vacuum pump.
Direct‑Fit Replacement: Matched dimensions and interface with OEM filters. Simple installation and replacement without equipment modification.

Working Principle of Leybold Vacuum Pump Exhaust Oil Mist Filter

During vacuum pump operation, vacuum pump oil mixes with airflow and forms oil mist discharged from the exhaust port. When oil‑mist‑laden gas flows through the Leybold vacuum pump exhaust oil mist filter, composite fiberglass media intercept oil mist particles. Fine oil mist agglomerates into droplets and flows back to the vacuum pump oil tank for recycling, while purified gas is discharged outside. Once the filter element is clogged and differential pressure rises excessively, the integrated safety valve opens for pressure relief to avoid vacuum pump damage caused by excessive backpressure.

Usage & Replacement Tips for Leybold Vacuum Pump Exhaust Oil Mist Filter

Replace your Leybold vacuum pump exhaust oil mist filter promptly if obvious oil smoke appears at exhaust outlet, abnormal noise occurs or vacuum pump oil consumption rises sharply, which indicates filter clogging.
Keep operating temperature below 110 °C to avoid accelerated aging of filter media.
Inspect fluororubber sealing ring during replacement to ensure proper sealing and prevent bypass oil‑gas leakage.
Bulk foreign trade orders are acceptable; sample and full‑container shipments are available. Welcome your inquiry.

FAQ about Leybold Vacuum Pump Exhaust Oil Mist Filter

Q: Can the Leybold vacuum pump exhaust oil mist filter be cleaned and reused? A: The fiberglass coalescing media cannot be cleaned or regenerated. A new filter element must be installed once clogged. Cleaning will permanently damage filtration precision.

Q: How to select the correct model? A: Confirm the full vacuum pump model (e.g. SV300B) or OEM part number printed on your old filter, then you can get the matching Leybold vacuum pump exhaust oil mist filter.
