Brand Introduction
Industrial facilities struggling with compressed air contamination face a recurring challenge: conventional filters either lack sufficient precision to meet stringent purity standards, or create excessive pressure drops that inflate energy costs. Wuxi Yuanmei Filtration addresses both pain points through advanced folded filter media technology and precision-engineered stainless steel housings.
Founded in January 2016 and headquartered in Wuxi, Jiangsu Province—China's advanced manufacturing hub—Yuanmei Filtration has evolved into a National High-Tech Enterprise with ISO 9001 certification. With over 20 years of cumulative technical expertise in compressed air treatment and 32+ authorized national patents, the company operates a self-owned ACF compressed air testing laboratory equipped with oil content analyzers, particle counters, and dew point sensors for comprehensive quality verification.
The YM Stainless Steel Threaded Filter Series delivers measurable results: filtration precision down to 0.01μm, residual oil content as low as 0.001ppm, fully compliant with ISO 8573-1 Class 1 ultra-high purity standards—representing 99.9999% particle interception efficiency. The low-pressure-drop design reduces system energy consumption by 15-25% compared to traditional filtration solutions, translating to significant operational cost savings over the filter's 24+ month stable service life.
Core Technology & Product Architecture
The YM Stainless Steel Threaded Filter Series features seven precision-calibrated models spanning flow capacities from 1.2 to 13.2 Nm³/min, accommodating diverse compressed air system requirements:
Premium Material Construction: SUS304/SUS316 stainless steel bodies with polished inner and outer surfaces (Ra≤0.3μm), certified by SGS for food and pharmaceutical-grade applications. Working pressure rated at 1.0MPa with standard G-threaded connections for straightforward installation and maintenance.
Multi-Grade Filtration Options: Six distinct filtration classes address specific contamination profiles:
Compact, Field-Proven Design: Seven standardized models (YM-ST001 through YM-ST013) offer optimized dimensional footprints. For example, the YM-ST005 (5.8 Nm³/min capacity) features a G1-1/2" connection, 160mm width, 480mm height, and 89mm diameter—ideal for space-constrained installations.
Advanced Filter Media Engineering: Self-developed folded filter elements incorporate aviation-grade materials with CFD-optimized flow paths, maintaining high dirt-holding capacity while minimizing pressure differential. Elements are fully interchangeable with international mainstream brands including Atlas Copco, Ingersoll Rand, and Parker, reducing maintenance complexity.
