Description
Three-lug chuck high-temperature filter cartridges adopt a three-lug chuck (triangular chuck) as the quick-mount interface. They are mainly applied to high-temperature preheating SLM equipment (100–150°C), special material printing and partial EBM Electron Beam Melting equipment.
This product is equipped with high-temperature resistant glass fiber filter media or PTFE membrane-coated high-temperature filter media, matched with high-temperature hot melt adhesive and FKM sealing components. Its continuous operating temperature ranges from 120°C to 200°C, with instantaneous temperature resistance up to 250°C. In compliance with EN 1822 standard, it reaches H13-H14 filtration grades with filtration efficiency of ≥99.95%–99.995% for 0.3μm particles. Featuring a three-lug chuck quick-mount design, the cartridge can be easily replaced under high-temperature conditions and is widely compatible with mainstream equipment such as EOS M290.
Core Technical Advantages
Quick-mount three-lug chuck design: Standard three-lug chuck interface allows full installation and removal by simply rotating 90 degrees without any tools. Even under high-temperature conditions, a single operator can finish replacement within 30 seconds, greatly cutting equipment downtime.
High-temperature resistant filter media system: Adopts high-temperature resistant glass fiber or PTFE membrane-coated filter media, operable at 120–200°C with instantaneous heat resistance of 250°C. The media maintains intact structure without shrinkage, softening or delamination under high temperatures.
High-temperature hot melt adhesive bonding: High-temperature resistant epoxy resin or thermosetting polyurethane adhesive is used to bond end caps and filter media. The cured adhesive layer features outstanding thermal stability and will not debond or crack after long-term operation at 150°C.
High-temperature sealing system: End cap sealing rings are made of fluoroelastomer (FKM) or silicone rubber, tolerating temperatures up to 200°C. They will not harden or lose elasticity after long service to guarantee reliable sealing under high heat.
High-temperature resistant support frame: The inner support frame is constructed of 304 stainless steel perforated mesh or thickened galvanized diamond mesh, featuring high collapse resistance and no deformation or oxidation at high temperatures.
Stable filtration efficiency at high temperatures: The microporous structure of glass fiber media remains stable under high temperatures without shifting filtration precision as temperature rises, keeping H13-grade efficiency consistently above 99.95%.

FAQ
Q1: What is the difference between three-lug chuck high-temperature filter cartridges and standard filter cartridges?
A: High-temperature filter cartridges adopt heat-resistant glass fiber media, high-temperature hot melt adhesive, FKM seals and stainless steel frames, enabling stable long-term operation at 120–200°C. Standard filters will soften and fail above 80°C.
Q2: How to confirm whether high-temperature filter cartridges are required for equipment?
A: Measure the operating temperature of the printing chamber. Heat-resistant cartridges (120°C rated) are required if operating temperature exceeds 80°C; dedicated high-temperature filter cartridges (150–200°C rated) are mandatory above 120°C.
Q3: Can high-temperature filter cartridges be used on room-temperature equipment?
A: They are technically usable yet cost-inefficient. Economical standard filters are recommended for normal-temperature applications, as high-temperature cartridges are purpose-built for heat-intensive working conditions.
Q4: How to determine the replacement cycle of high-temperature filter cartridges?
A: The cycle depends on operating temperature, printing materials and fume concentration. Replacement every 800–1200 hours is recommended for 100–150°C working conditions; every 600–1000 hours for 150–200°C environments. High temperatures accelerate media aging, so differential pressure monitoring is advised.
