1. Premium Multi-Layer Filtration Material
Core filter medium: Imported German glass fiber filter paper, high filtration efficiency, low pressure drop, excellent anti-corrosion performance, stable filtration performance under long-term high temperature operation.
Surface protective layer: Special PET oleophobic fabric, strong oil repellency, flame retardant and corrosion resistant, prevent fine glass fiber shedding.
End cap material: PA66+GF30 reinforced plastic, high temperature resistance up to 110℃, wear-resistant, high hardness, no deformation under continuous working heat.
2. Ultra-High Separation Efficiency & Stable Pressure Drop
Filtration efficiency ≥99%, almost all lubricating oil mist can be coalesced and recycled back to the pump oil tank, greatly cutting oil consumption cost.
Initial pressure drop <10kPa, stable operating pressure drop ≤30kPa, will not increase pump load or affect ultimate vacuum degree during the whole service cycle.
Wide working temperature range, long-term safe operation below 110℃, suitable for continuous industrial production 24/7.
3. Full Series Matching for Busch RA Rotary Vane Pumps
We supply 5 complete models LOA-910 / LOA-911 / LOA-912 / LOA-913 / LOA-914, covering mainstream BUSCH RA0020F to RA0630B single-stage vacuum pumps, one-to-one interchange with original OEM filters, direct replacement without modification.
4. Cost-Effective Replacement Solution
Compared with genuine Busch original filters, our exhaust filter elements have equivalent filtration performance but lower procurement cost; stable structure prolongs replacement cycle, reduces downtime and maintenance labor cost.
5. Eco-Friendly & Clean Workshop
Clean exhaust air without oil mist emission, meet global industrial environmental protection standards; no oil stain on workshop floor, machinery and product surfaces, improve working environment and staff health safety.
