Products Description
The coalescing filter cartridge is a critical functional element in precision filtration systems, specifically engineered for liquid-liquid and gas-liquid separation. Its primary purpose is to efficiently remove emulsified water and minute liquid droplets from hydrocarbon fluids or gas streams . The cartridge serves a dual function: it filters out solid particulate contaminants from the media while simultaneously demulsifying and coalescing emulsified water droplets into larger, separable water globules, thereby achieving deep purification.
coalescing filter for compressed air
*High pollution capacity Imported filter materials are selected, which can accommodate high quality particle pollution per unit area, large pollution capacity, and long service life.
*Stable filtering accuracy Good processing technology reduces the
damage of filter materials caused by mechanical force during wave bending processing, which can cause filtration failure andensure stable and uniform filtration accuracy of the filter element.

FAQ
Q1: How can I tell when the cartridge needs replacement?
Replacement is primarily determined by the operating differential pressure, rather than by time alone. When the pressure drop rises to 0.15 MPa (approx. 15 psi), the cartridge is severely clogged and must be replaced. Additionally, if the effluent free water content consistently exceeds the process limit, replacement is advised even if the pressure drop is still below the threshold. We recommend keeping regular records of initial and operating pressure drops for optimal maintenance scheduling.
Q2: Is the cartridge suitable for media containing surfactants?
Special attention is required: the coalescing performance is significantly inhibited in media with high surfactant content (e.g., emulsifiers or additives). Surfactants reduce the oil-water interfacial tension, preventing small droplets from coalescing into larger ones. If your media contains such components, we recommend upstream pretreatment (e.g., demulsifier injection or heating/settling) or selecting our specially designed anti-emulsification enhanced cartridge.
Q3: Can the cartridge be cleaned and reused?
No, the coalescing cartridge is a single-use consumable and is not recommended for cleaning and reuse. Washing or chemical backwashing will damage the microscopic fiber structure and surface treatment of the glass or polyester media, causing irreversible loss of coalescing efficiency and potential fiber shedding, which may contaminate downstream systems. To reduce operating costs, we suggest installing a pre-filter upstream to protect and extend the service life of the main coalescing cartridge.
