Hilco Oil Mist Eliminators

The HILCO Oil Mist Eliminator is the answer to economically reclaiming the oily vapor found in the air stream of vents of lubricating oil systems on large, highspeed rotating equipment.

These include gas turbines, steam turbines, turbo compressors, reciprocating engines and gearboxes. The Oil Mist Eliminator improves safety by eliminating oily residue caused by setting oil mist on engine room floors, equipment and stairways. It also keeps the environment clean and helps prevent exterior oil contamination of buildings and grounds.

Multiple versions are available. Coalesce only and coalesce with blower and silencer. Both models with coalescers eliminate oil mist with 99.97% efficiency regardless to partial size.


Blower-Assisted Oil Mist Eliminator is the most efficient design for oil systems that cannot withstand back pressure or where back pressure may not be desirable. It can be installed with an air flow-restriction device to pull vacuum. It is also designed to maintain atmospheric condition in the oil system.


HILCO Oil mist eliminators prevents oil mist from contaminating air or soil, helping facilities comply with environmental regulations. It also makes for a cleaner, safer work environment by eliminating oily residue buildup on engine room floors, enclosures and stairwells, while improving indoor/out-door air quality and reducing fire hazards.


Custom oil mist eliminators can be sized for your system. To place an order for a HILCO vent oil mist eliminator, you will need to have the following measurements: vent size, temperature of flow, flow rate (ACFM), and allowable back pressure and/or vacuum.
