YHB Eco Oil Mist Collectors: A Guide to the YMC and YOC Series
YHB Eco is a South Korean manufacturer of oil mist collectors and coolant cleaning equipment for machine tools. The company has been in business since 1987, and its mist cleaner catalog lists ISO 9001 and ISO 14001 certification. IndustryNest is the authorized US distributor for YHB Eco and also serves as its US office, so customers here can get sales and product support locally.
What an oil mist collector does
Machining with coolant or cutting oil throws a fine mist into the machine enclosure. When that mist escapes, it settles as an oily film on floors, machines and electrical cabinets, and operators end up breathing it.
A YHB Eco mist cleaner mounts on the machine and pulls air out of the enclosure. It separates the mist using centrifugal force and filters, then sends the collected liquid back through a drain hose. YHB Eco lists machining centers, milling machines, CNC lathes, tapping machines and EDM among the typical applications.
YMC or YOC: start with your cutting fluid
- YMC type: for water-soluble coolant. This is the standard model.
- YOC type: for straight (non-water-soluble) cutting oil. It adds a chip separator with a glass filter ahead of the collector.
Both types come in four sizes and run on 3-phase 220V, 380V or 440V power.
Sizes at a glance
| Size | Motor | YMC air flow | YOC air flow | Inlet and outlet |
|---|---|---|---|---|
| 300 | 0.4 kW | 7 m3/min (about 247 CFM) | 5 m3/min (about 177 CFM) | 100 mm |
| 350 | 0.75 kW | 12 m3/min (about 424 CFM) | 10 m3/min (about 353 CFM) | 125 mm |
| 400 | 1.5 kW | 25 m3/min (about 883 CFM) | 20 m3/min (about 706 CFM) | 150 mm |
| 420 | 2.2 kW | 30 m3/min (about 1,059 CFM) | 25 m3/min (about 883 CFM) | 150 mm |
Air flow figures are YHB Eco's catalog ratings at 60 Hz. At 50 Hz, air volume drops by about 20%. The right size depends on your enclosure volume, duct run and how much mist the process makes, so send us the machine model if you are not sure.

A, C and F variants
YHB Eco also builds each size in three variants, shown by a letter after the model number:
- A type: adds a cleaning nozzle for the fan and body, so the unit can be washed in place.
- C type: uses a reusable demister filter instead of the polyester filter.
- F type: adds a filter service indicator that shows the filter's condition.
If you need one of these, call us and we will check availability with YHB Eco.
Filters and after filters
Standard YMC and YOC units use polyester filters. We carry replacement filters for the YMC-350 and YMC-400 sizes.
An after filter is an optional second stage that mounts on the outlet for finer mist. It reduces air flow by about 8%, so allow for that when sizing. After filter sets are available for the 350 and 400 sizes.
Other YHB Eco products
We also list YHB Eco's coolant chip cleaners, the YHB-20S and YHB-40S, which pull chips and fines out of the coolant sump, and the YHB coolant gun.
