Excess pressure in the system forces the air through the two-stage slosh protection. Here, the large oil particles are blocked and drip back into the system. The subsequent demister is used for condensation of larger oil particles, which stick to it, condense and also drip back.
Finer particles are separated at the 3 µm glass fiber filter and returned to the tank. Only the finest oil aerosols end up in the high bulk activated carbon. The 4 mm cylindrical pellets adsorb all remaining particles and thus protect the environment from contamination. At the end of the adsorber life cycle, the bottom white silica gel layer turns a brownish oil-like color, indicating the end of the operating interval.
Due to the valveless design and multi-stage separation, this adsorber has a high efficiency for separating particles from the system to the environment and a low differential pressure.
VG-D adsorbers are made of polycarbonate, polyamide, activated carbon as well as FKM seals and can be used for the deaeration of all common hydraulic and gear oils, lubricants, fuels and isocyanates.
