Product Overview
Copper powder sintered filter element is a porous filter element made of copper alloy powder sintered at high temperature, and its core function covers three major fields: filtration, protection and functional enhancement.
1. Efficient filtration and purification
Liquid filtration: It can intercept solid particles in hydraulic oil and fuel (accuracy 1-100μm), prevent equipment wear, and extend mechanical life.
Gas purification: remove the oil-water mixture and dust in the compressed air to ensure the stable operation of the pneumatic components.
Deep filtration mechanism: The internal three-dimensional mesh pores trap tiny particles through inertial collision and diffusion adsorption, and the pollution absorption is increased by 40%.
2. Safety protection characteristics
Flame retardant and explosion-proof: suitable for flammable environments (such as mine pressure air systems), blocking flame propagation through pores.
Corrosion protection: Resistant to strong corrosive media such as hydrochloric acid and seawater, and protect chemical equipment pipelines.
3. Additional function enhancement
Airflow noise reduction: The porous structure converts airflow sound wave energy into heat energy, reducing equipment noise by more than 30 decibels.
Thermal management assistance: High thermal conductivity (copper-based material) helps the equipment dissipate heat and avoid local overheating
Typical application scenarios
4. Industrial field
Petrochemical: filtering catalyst slurry, recovering precious metal particles.
Energy equipment: lithium battery electrolyte precision filtration (accuracy 0.5μm), nuclear power boric acid solution purification.
Pneumatic system: The SMC air source processor filters oil and water and dampens sound
Special environment
Mine pressure air self-rescue device: provide clean breathing gas, synchronous noise reduction and explosion prevention.
Marine/aviation: high-pressure fuel filtration to adapt to salt spray corrosion environment.
