Xinxiang Filter

Description:
Replacement square filters for EOS M400 are alternative filter elements specially designed for large-format M400 series metal 3D printing equipment manufactured by Germany’s EOS.

Designed in accordance with EN 1822 standard, this product comes with H13-H14 filtration grades, delivering particle efficiency of ≥99.95%–99.995% for 0.3μm particles and initial resistance ≤250Pa. Its dimensions precisely match the filter chamber of M400 printers with 100% compatible sealing interfaces, making it an ideal replacement solution for terminal high-efficiency filtration in M400 gas recirculation systems.

Core Technical Advantages:

Terminal high-efficiency filtration: H13/H14 filtration grades guarantee ultra-high cleanliness of recirculating gas inside large build chambers and maintain stable print quality during long-duration printing.

High dust holding capacity design: The large-volume square structure accommodates more filter media, boosting dust holding capacity by over 50% compared with M280 filters and extending the replacement cycle to 2000–3000 hours.

Compatible with four-laser models: It meets the higher airflow demand of four-laser M400 printers and maintains stable filtration performance.

Application Fields:

EOS M400 Series Equipment

Applicable Printing Materials (for large-sized parts):

Titanium Alloy (Ti6Al4V)

Nickel-Based Alloy (Inconel 718)

Aluminum Alloy (AlSi10Mg)

Stainless Steel (316L)

Typical Applications:

Aero-engine casings

Aerospace structural components

Large medical implants

Mass production of automotive components

Case & Data Verification:

Case: Square Filter Replacement for EOS M400-4 at an Aerospace Manufacturer

An aerospace manufacturer adopts four-laser EOS M400-4 printers for mass production of aero-engine parts. Original square filters need to be imported from Europe, resulting in long procurement lead times and heavy spare parts inventory pressure. After switching to domestic replacement H13 square filters, the units pass on-board PAO leak tests. The pressure differential stays below 400Pa after 2500 hours of continuous operation, printed components meet aerospace certification standards, and procurement costs are cut by approximately 45%.

FAQ

Q1: What special filter requirements does the four-laser M400-4 version have?
A: The M400-4 features higher exhaust airflow, requiring filters with larger dust holding capacity and slower pressure drop rise. The replacement filters are optimized with heavier media weight and deeper pleats for this demand.

Q2: Will replacement filters affect the consistency of parts printed by four-laser M400-4 printers?
A: No. The filter’s filtration precision complies with equipment specifications, and consistent print quality has been verified through customer mass production trials.

Q3: Does the sealing gasket of square filters need regular separate replacement?
A: The sealing gasket shall be replaced together with the filter cartridge to prevent leakage caused by aging of old gaskets.
