Coalescer Filters - Engine Room Consumables and Spares

Coalescer filters are separator elements used in marine engine rooms to remove liquid droplets, water, oil mist, and fine contaminants from fuel, lubricating oil, compressed air, or oily-water streams. They are normally replaced as consumable filter elements or coalescer packs.

ProShipWorks provides end-to-end support to source and supply Coalescer Filters for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Standards, Certifications & Class Approval

Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.

Applicable Standards & Certification System-level requirements may include IMO MEPC.107(49) for shipboard oily-water separators. Filter elements should be supplied to the original equipment manufacturer's specifications; no single universal standard applies to all marine coalescer elements.
Class Approval Approval is normally associated with the complete separator or treatment system rather than the replacement element alone. Depending on the equipment, relevant societies may include DNV, ABS, Lloyd's Register, Bureau Veritas, and ClassNK.

Installation, Maintenance & Safety Information

Installation Notes Confirm the element part number, dimensions, flow direction, seal material, and micron or separation rating before installation. Isolate and depressurize the system, clean the housing, lubricate compatible seals, and verify correct seating and sealing.
Maintenance Tips Replace at the manufacturer's differential-pressure limit or scheduled interval. Monitor pressure drop, leakage, water carryover, and treatment performance. Keep spare elements sealed and dry in their original packaging.
Safety Notes Isolate, depressurize, and drain the equipment before opening the filter housing. Treat removed elements as contaminated waste where applicable. Use required PPE and follow fuel, oil, bilge-water, and enclosed-space safety procedures.
