Coalescing Filter Elements
Two coalescing element technologies — standard C-type for compressed air and process gas, plus CS-type with silica binder for vacuum pump exhaust service at elevated temperatures.
C-Type Coalescing Elements
Standard coalescing elements for compressed air and gas service
C-type coalescing elements use borosilicate glass microfibre media with a fluorocarbon (PVDF) binder, designed for removing liquid aerosols — oil, water, and hydrocarbon mist — from compressed air and process gas streams. Available in four efficiency grades, from general-purpose pre-filtration to ultra-high-efficiency final-stage coalescing.
Key Features
- Grade HE: 99.99% efficiency at 0.1 µm — ISO 8573-1 oil Class 1 (aerosol)
- Grade ME: 99.5% efficiency — high-quality general use
- Grade ST: 95% efficiency — general-purpose pre-filtration
- Grade PF: 75% efficiency — bulk liquid removal pre-filter
- Replace at 0.7 bar differential pressure
- Cannot be cleaned or regenerated — replace when loaded
CS-Type Coalescing Elements
Purpose-built elements for vacuum pump exhaust service
CS-type elements use a silica-based binder instead of fluorocarbon, providing superior thermal stability to 200 °C and optimised performance with the high oil loading typical of vacuum pump exhaust. These elements include an anti-reintrainment outer mesh to prevent coalesced oil from being stripped back into the gas stream.
Key Features
- 99.9% efficiency at 0.1 µm — Grade HE (CS)
- Silica binder: thermally stable to 200 °C (vs. 150 °C for C-type)
- Optimised for high oil loading in exhaust duty
- Anti-reintrainment mesh prevents coalesced oil re-entrainment
- Available in 4 sizes for the complete vacuum pump housing range
- Replace based on differential pressure or annual schedule
