Operation principle: Under the function of pressure, the gas gets into the filter. The grains of larger solid sharply and the ones of smaller moves freely. The element catches these grains through three types of screening, blocking and resisting. Due to the attracting function of filter element material numerator, the liquid is attracted to form larger drop. The filter element gets wet after attracting the drop to the fiber. More and more empty blanks among the filter element are filled up with solid and liquid. The drops getting into the separation cavity are caught by the mist eliminator and separated out gas. Application area: Natural gas, coal gas, gas, liquefied petroleum gas and other gas Main function: This filter can eliminate the solid grains and drops carried during the process of transport to ensure the normal operation of pipe system and equipment.
