Precision Filtration Series:
ACF Precision Filters: 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 ultra-high pressure. The patented drainage structure and interface design ensure secure sealing and easy maintenance, making them ideal for semiconductors, laser cutting, medical equipment, and food processing.
MICRON High-Efficiency Filters: Designed for ultra-precision applications with flow ranges of 1.2–13 Nm³/min, these filters eliminate trace dust, oil, and moisture that can damage sensitive electronics or optical coatings. They support both manual and automatic drain configurations for operational flexibility.
High-Pressure Filters: Constructed from premium materials to handle working pressures up to 30-50 MPa, these filters achieve ultra-low oil carryover rates as low as 0.01 ppm. The optimized internal structure minimizes pressure drop, reducing energy consumption and system load.
ESP Filter with Internal Pleated Cartridge: A flagship innovation delivering 99.9% particle interception rate with 3–5 times larger filtration area than conventional designs. Constructed with 304/316L stainless steel body and PP/PTFE/stainless steel pleated cartridges, it features low pressure drop (≤70Pa), corrosion resistance up to 200℃, and compliance with ISO, FDA, and GMP standards.
Stainless Steel Series:
Sterile Filters: Made from food-grade 304/316L stainless steel with surface polished to Ra≤0.8μm, meeting GMP and FDA standards. Equipped with PTFE, PP, or hydrophilic polyethersulfone filter elements at 0.22μm/0.45μm precision, achieving 99.999% sterilization rate. Suitable for pharmaceutical liquid filtration, food & beverage processing, and compressed air sterilization.
Threaded and Flanged Filters: Offering 10-300 mesh customizable filtration precision with 1.6-10MPa pressure resistance, these filters feature industry-standard connections (ANSI/PN optional) for secure, leak-proof installation in industrial pipelines and compressed air systems.
Auxiliary Equipment:
XY Series Silencers: Adopting composite noise reduction technology to achieve 20-45dB(A) noise reduction efficiency, made of 304/316L stainless steel with working temperature range of -20℃ to 250℃ and low pressure drop (≤70Pa).
KS Series Diffusers: Utilizing precision vacuum sintering technology with customizable pore size (0.1-120μm) for uniform gas/liquid dispersion in wastewater treatment, chemical processing, and bioreactors.
