Equipped with filtration precision of 0.22μm/0.45μm, it achieves a sterilization rate of up to 99.999%. The filter body withstands working pressures up to 1.0-1.6MPa and temperatures from -10℃ to 120℃, with flange-type or clamp-type connections allowing quick filter element replacement.
ESP Filter with Internal Pleated Cartridge: Delivers 3-5 times larger filtration area than conventional designs with 99.9% particle interception rate. The 304/316L stainless steel body features corrosion resistance up to 200℃, with PTFE cartridges rated to 250℃. Pressure drop remains ≤70Pa, and the detachable pleated cartridge enables quick replacement without pipeline shutdown, extending service life 1.5-2 times longer than ordinary cartridges.
Technical Testing Infrastructure: The company operates an ACF Testing Laboratory equipped with German CS Testing Instruments including 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 down to -80°Ctd). This infrastructure validates filtration efficiency, pressure drop, and dew point performance against ISO 8573 Class 1 standards.
