Is This a Liquid Ink Filter?

A printer can contain liquid ink filters, tank vents, mist filters and cooling-air filters. Their names may look similar in search results, but the application matters. Check the parts diagram or service record to identify the circuit before ordering.

For example, Mimaki describes a UV-lamp filter used to keep dust and ink mist away from the lamp assembly. That is a different maintenance task from filtering liquid ink. Mimaki's UV-lamp filter guidance.

• Record whether the part serves a supply line, a return or circulation line, a vent, or a cooling system.
• Identify the ink channel and the filter's position from the machine documentation.
• Keep any direction markings and port labels in your reference photos.

If you are still comparing capsule and disc shapes or investigating flow symptoms, start with our inline filter format and troubleshooting guide. Here, the focus is specifying a UV liquid-ink replacement.

5µm vs 10µm: Which Option Matches Your Order?

The capsule product page contains several options. Its page title is not enough to identify the selected item: the current black CBT options include the following two different codes.

These values come from the current store options and reference labels. They are not independent filtration test results. The listing does not establish a nominal or absolute rating basis, a retention-efficiency test, or the pressure-drop curve for your ink.

Filter manufacturers distinguish between nominal and absolute product ratings. Parker, for example, lists these as separate filtration categories. Ask for the exact filter's rating definition and test basis when comparing suppliers; do not treat the micron number as a complete performance specification. Parker's inks, paints and coatings filtration reference.

A useful supplier question is: “Does this exact code meet the original filtration requirement at our ink's operating viscosity and required flow?” Include the machine specification instead of asking only whether 5µm is better than 10µm.

Does Black Housing Mean the Filter Is Suitable?

Opaque housing can help protect UV-curable ink from light, but housing color alone does not approve the complete filter. Pall describes light-blocking housings for its UV capsule range and separately addresses compatibility with the fluid being filtered. That is a selection principle, not a specification for the store products in this article. Pall's UV capsule filtration reference.

• Ink identity: provide the manufacturer, exact ink series and color or channel, including white where applicable.
• Wetted materials: request compatibility information for the filter medium, housing, seals and supplied adapters.
• Operating conditions: confirm the system's temperature, pressure and flow requirements against the offered filter's documentation.
• Maintenance fluids: confirm any approved priming or cleaning fluid separately; ink compatibility does not approve every solvent.

The store lists the black capsule options for UV applications. Still confirm the exact ink formulation and machine arrangement. Do not transfer an approval from water-based DTF ink to UV ink, or infer white-ink suitability from the color of the filter body.

Check Both Ends, Even Within the Same Filter Family

The caliper is an inspection prop, not a measurement. The reference is the Black 6*4 Tube option; no tube dimensions can be established from this scene.

The JYY-F-2600 page offers both Black 6*4 Tube and Black Push-in 6*4 options. These are different selections. The product card below opens the Black 6*4 Tube option, whose listing describes a screw connection.

Confirm the meaning of “6 × 4” with a labeled drawing showing tube ID and OD. Likewise, the capsule listing's bare “6mm” tube description needs clarification before it can establish a match.

• Compare both inlet and outlet: fitting style, mating dimensions, seal location and retention method.
• For threaded connections, ask for the thread standard and size; a photo cannot establish them reliably.
• Confirm which nuts, barbs, seals or adapters are included in the selected option.
• Check body clearance and access for replacement without bending the existing tubing into an unsuitable route.

The JYY listing provides no micron rating for this option. Do not treat it as a documented 5µm or 10µm substitute. Resolve the filtration specification and ink compatibility as well as the connector match.

For a fuller explanation of tube dimensions and mating connections, see our connector-size buying checklist. Do not stretch tubing or force mismatched fittings to make a replacement fit.

Inspect the New Filter Before Opening the Ink Circuit

Illustrative receiving inspection. Match the delivered label and fittings to your approved order; the pictured batch details do not identify current stock.

1. Check the delivery: compare the complete code, selected micron option, connector configuration and included accessories with the order. Inspect the housing and connections for damage.
2. Prepare the service procedure: follow the printer manufacturer's shutdown and isolation instructions, including pressure release where required. Use the ink safety data sheet for handling and protective equipment.
3. Protect the open circuit: have the correct replacement ready, keep connections clean and limit UV ink's exposure to curing light. Do not open a line merely to compare an uncertain part.
4. Install and prime as specified: a qualified technician should follow the machine's documented direction, sealing and priming procedure. Do not improvise pump pressure or force ink through the printhead.
5. Verify before production: perform the prescribed leak, supply and nozzle checks. Record the installed code and service date for the next order.

There is no universal replacement interval supported here. Follow the machine's maintenance schedule and any documented filter condition limits. A repeated restriction may call for investigating ink condition or the supply system, rather than repeatedly installing a finer filter.
