What maintenance schedule is recommended for the DEP compressed air fine filter, SYNTESIÂ® series to ensure optimal performance and when should the coalescing cartridge be replaced?

For optimal performance of the DEP compressed air fine filter, SYNTESIÂ® series: - Daily/weekly: Check pressure drop across the filter and inspect visual condition. Verify condensate drain operation (manual or semiâautomatic RMSA) and remove accumulated condensate to prevent carryover and element saturation. - Monthly: Inspect housing, connections and seals for leaks or damage. Ensure operating pressure and temperature remain within specified limits (SY1 up to 15 bar, SY2 up to 13 bar; temperature â10Â°C to +50Â°C). - Every 3â6 months (or sooner under heavy use/dirty intake): Measure differential pressure; if pressure drop approaches the manufacturerâs recommended limit or increases significantly from baseline, service is required. - Replacement of the coalescing cartridge: Replace the coalescing cartridge when the differential pressure reaches the recommended service threshold or when filter performance declines (e.g., visible carryover of liquid/particulates, decreased air purity). As a guideline, replace every 6â12 months under normal conditions; shorten interval for higher contaminant loads or continuous operation. Always follow field differential pressure indicators and visual/operational signs first. Sizes and flow guidance: follow the recommended flow rates (SY1: 460 l/min, SY2: 620 l/min at 6.3 bar) to avoid overload and premature cartridge saturation.

How does the DEP compressed air fine filter, SYNTESIÂ® series perform at varying inlet pressures and temperatures, and does efficiency change between SY1 and SY2?

DEP compressed air fine filter, SYNTESIÂ® series maintains high filtration efficiency across its specified operating range. Both sizes use a coalescing cartridge delivering 0.01 Âµm filtration (ISO 8573-1 class 1-7-2). Operating temperature range is â10Â°C to +50Â°C; within this range efficiency remains consistent provided condensate is drained properly (manual or RMSA semi-automatic). Supply pressure limits differ: SY1 up to 15 bar, SY2 up to 13 bar. Recommended flows at 6.3 bar are 460 l/min (SY1) and 620 l/min (SY2). In short, performance is stable across the allowed temperatures and pressures; the main differences are maximum allowable supply pressure and recommended flow rates, not filtration efficiency between SY1 and SY2.

Can the DEP compressed air fine filter, SYNTESIÂ® series be used with oil-lubricated compressors and does the coalescing cartridge handle oil aerosols?

Yes. The DEP compressed air fine filter, SYNTESIÂ® series can be used with oil-lubricated compressors. Its coalescing cartridge is specifically designed to remove very fine liquid aerosols and solid contaminants from compressed air with high efficiency (filtration down to 0.01 Âµm, ISO 8573-1 class 1-7-2). This means oil aerosols produced by oil-lubricated compressors will be coalesced into larger droplets and separated from the air stream, providing high air purity. Ensure you select the appropriate size (SY1 or SY2) for your flow and pressure conditions (SY1 up to 15 bar, SY2 up to 13 bar) and follow recommended maintenance and condensate drain procedures (manual or semi-automatic RMSA) for optimal performance.
