Description:
Six-lug chuck flame-retardant antistatic filter cartridges adopt a six-lug chuck as the mounting interface. They are mainly used for large-format metal 3D printing equipment such as EOS M400-4 and SLM 500, as well as high-air-pressure filtration systems, capable of handling larger air flow volumes and higher pulse backblowing pressure.

Nano nitrogen-based flame retardants and embedded conductive carbon fiber mesh are incorporated into the filter media, achieving UL94 V-0 flame retardancy grade with surface resistance ≤10⁹Ω. Compliant with EN 1822 standard, it reaches H13-H14 filtration grades with 99.95%~99.995% efficiency for 0.3μm particles. The model φ324×660mm features a filtration area of 18–22 ㎡ and a long replacement cycle of 2000–3000 hours.

Core Technical Advantages:

Stable locking with six-lug chuck: Six evenly distributed clamping jaws deliver balanced locking force to withstand intense differential pressure shocks. It is especially suitable for high-air-volume, high-frequency pulse backblowing scenarios of four-laser large-format printers.

Dual flame-retardant and antistatic safety: The media undergoes integrated flame-retardant and antistatic treatment. Nano nitrogen-based flame retardants prevent flame spread, while embedded conductive fiber mesh rapidly dissipates static electricity, meeting safety standards for high-risk materials such as aluminum and magnesium alloys.

Large filtration area and high dust holding capacity: Optimized pleat height and density deliver a filtration area of 18–22 ㎡ for the φ324×660mm model, boosting dust holding capacity by over 30% compared with standard cartridges and extending service intervals.

Surface filtration with PTFE membrane coating: The coated layer forms a dense filter membrane with pore size below 200nm, trapping dust on the membrane surface for thorough ash cleaning and stable pressure drop.

Case & Data Verification

Case: Safety Upgrade of Large-Format EOS M400-4 Equipment in an Aerospace Manufacturer

An aerospace manufacturer adopts four-laser EOS M400-4 equipment for mass production of aluminum alloy aerospace components fitted with six-lug chuck H13 flame-retardant antistatic filter cartridges. Test results show V-0 flame retardancy grade (2 seconds of afterflame) and surface resistance of 6.5×10⁸Ω. The filter remains intact after 2500 hours of continuous operation with stable part quality, and no static or fire safety incidents occur. The six-lug chuck maintains firm locking without vibration loosening during high-frequency pulse backblowing.

FAQ

Q1: What special requirements apply to filter cartridges for large-format equipment?
A: Large-format printers feature higher air flow and more frequent pulse backblowing, which requires filters with larger filtration area, higher compression resistance and more secure locking structures.

Q2: Are flame-retardant antistatic filter cartridges applicable to titanium alloy printing?
A: Yes. Though titanium powder is less flammable than aluminum powder, splashing sparks still carry ignition risks; flame-retardant antistatic filters provide extra safety protection.

Q3: What is the operating temperature range of this filter cartridge?
A: The standard version operates below 120°C with instantaneous heat resistance up to 150°C. High-temperature customized versions with heat-resistant flame retardants and fluoroelastomer seals are available for high-temperature environments.
