ACF Precision Filter Series: Featuring aviation-grade silicon-aluminum alloy construction with multi-layer surface treatment (internal electrophoretic and external epoxy coating), these filters withstand up to 4.0 MPa pressure while achieving 99.9% filtration efficiency. The patented interface design ensures secure sealing and prevents system leaks in high-pressure food processing environments.
Stainless Steel Sterile Filters: Constructed from food-grade 304/316L stainless steel with surface polishing to Ra≤0.8μm, these units meet GMP and FDA standards. Equipped with PTFE, PP, or hydrophilic polyethersulfone filter elements at 0.22μm/0.45μm precision, they achieve 99.999% sterilization rates, effectively intercepting bacteria, spores, and microorganisms. The filters withstand working pressures up to 1.0-1.6MPa and temperatures from -10℃ to 120℃.
ESP Filter with Internal Pleated Filter Cartridge: This flagship product delivers 3-5 times larger filtration area than conventional filters, with 0.1-60μm customizable precision and 99.9% particle interception rate. The low pressure drop design (≤70Pa) reduces system energy consumption by 15%-25%, while the detachable pleated cartridge enables quick replacement without pipeline shutdown.
Gas-Water Separators: Utilizing advanced centrifugal separation technology, these units achieve 99.9% separation efficiency for liquid water, oil mist, and solid contaminants, ensuring dry compressed air output essential for food contact applications.
The company's testing infrastructure includes German CS Testing Instruments (OIL-Check 400 measuring residual oil to 0.001mg/m³, PC400 Particle Counter detecting particles down to 0.1μm, and FA510 Dew Point Sensor measuring pressure dew points to -80°Ctd), enabling rigorous verification against ISO 8573-1 Class 1 standards.
