Excess pressure in the system forces air containing oil out of the system. Large oil droplets are retained at the two-stage slosh guard and drip back into the system. The demister is used to condense larger oil particles, which stick to it, condense and also drip back.
Finer particles are separated at the 3µm glass fiber filter and returned to the tank. Only the finest oil aerosols end up in the high volume activated carbon. The 4mm cylindrical pellets adsorb all remaining particles, protecting the environment from contamination. At the end of the adsorber’s 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 in separating particles from the system and a low differential pressure.
