INTRODUCTION

GU-H series filters are high pressure type and used in the pressure line of hydraulic system. Filter element is made of glass fibre.This new filter media has high efficiency and large dirt capacity.The absolute filtration is high.beta ratio is over 100.

The differential pressure indicator signals when pressure drop across elementreaches 0.35MPa.As the pressure drop rises to 0.4MPa,the by-pass valve in this filter will open allowing oil flowing directly. When the element being changed or cleaned, the oil of system can counter flow to prevent air and contaminant entering the system.The counter flow has not been filtered and is quarter of this filter flow rate.

Filter using the new chemical filter material, so it has high filtration precision, through the oil capacity, the original pressure loss, pollutant carrying capacity, etc., the filtration precision absolute filtration precision calibration, filtering than β3,5,10,20> 200 filtration efficiency n≥99.5%, in line with ISO standards.
