Oil Mist Trap

オイルミストトラップ

Oil mist is pump oil fumes expelled with exhaust gas as oil-sealed rotary vacuum pumps operate.
Oil mist generation is particularly marked in the pressure range between atmospheric pressure and 133.3Pa, in which the load of suction → compression → discharge action is heavy. Oil mist trap elements catch the mist and prevent oil from leaking out and polluting the environment. This particular feature also helps reduce exhaust noise.

Oil mist trap (Standard type)


オイルミストトラップ オイルミストトラップ( 標準型)

Used when piping beyond the oil mist trap is not required. Change the elements periodically because oil mist leaks when the elements are saturated

 

Oil mist trap (Directional type)


オイルミストトラップ( インライン型)  オイルミストトラップ( インライン型) 

Used when piping to ventilation duct or outdoors is required. Change the elements periodically, since saturated elements increase exhaust resistance and lead to pump overload.
