Oil Mist Collectors
Smart-Alert Flagship Series
GEP-200M / GEP-300L
Upright vortex impeller draws air first, then filters — higher airflow and lower vibration than horizontal units.
Pollution-control equipment for machine tools · Designed and made in Taiwan
Oil mist, tramp oil and tank-bottom chips —
handled separately, at the machine
Since 2011, GREEN ECO PRO has built pollution-control equipment for machine tools: oil-mist collectors, coolant purification, chip and sludge removal, and precision filtration. Tell us about your machines, coolant tanks and the problems you see on the floor, and we'll work out the right model together.
- Taiwan precision manufacturing
- Industrial pollution control
- Custom engineering
- Better factory environments
Coolant changes, tank cleaning, consumables —
which costs can be reduced?
Coolant purchasing, manual skimming and tank cleaning, and outsourced waste-fluid disposal often add up to more than the equipment itself. GREEN ECO PRO separates tramp oil and contaminants by physical means — no additives, and no change to the coolant's original concentration. How much you save depends on your machining, fluid type and volume, and has to be assessed on site.
- Less manual skimming, tank cleaning and fluid changes
- Lower waste-coolant disposal fees and collection frequency
- Higher fluid recovery, less new-coolant purchasing
- Dewatered metal chips fetch a higher recovery value
- A better air and odour environment for operators
- Less oil build-up around machines, keeping them clean
There is no universal figure for the improvement. The result depends on machining method, coolant type, number of machines, and your current change and cleaning intervals. Send us your tank capacity and maintenance cycle and we will help you estimate it.
Four kinds of pollution, four responses
First identify whether the problem is in the air, the fluid or the tank bottom — then choose the right equipment.
Oil-mist control
Extract machining oil smoke and fine particulates at the source, preventing mist from spreading across the plant.
Common problems
- Oil mist and smoke atomised during CNC machining
- Declining plant air quality and visibility
- Long-term oil build-up around machines and on floors
- Prolonged operator exposure to an oil-mist environment
Our approach
- Upright design draws air first, then filters — stronger airflow, lower vibration
- Vortex impeller with multi-layer high-precision, washable filters
- Optional activated-carbon smoke tube captures smoke to 1μm and suppresses odour molecules
Equipment & technology
- GEP-series upright oil mist collector
- Original 2-D turbine blade (CE certified)
- IE3 ultra-high-efficiency motor
- Smart filter-saturation alert light
Benefits
- Upright layout draws air first, then filters — high airflow, low vibration
- Filter rated at 5μm; optional activated-carbon tube handles smoke and odour
- Alert light flashes when the filter saturates, so maintenance timing is visible

Coolant purification
Continuously remove surface tramp oil to reduce the oil layer anaerobic bacteria depend on — without changing the coolant's original concentration.
Common problems
- Coolant turning rancid and breeding anaerobic bacteria
- Fine chips and impurities contaminating the fluid
- Short service life and frequent fluid changes
- High new-coolant purchasing and waste-disposal costs
Our approach
- Patented floating skimmer self-adjusts to the level; operates from just 5 cm depth
- Patented S.T.P.M module, one-shot moulded from non-oleophilic material, speeds continuous oil separation
- Physical separation without changing coolant concentration or base oil
- Optional UV-C sterilisation suppresses anaerobes and nitrification
Equipment & technology
- Ultra-series pneumatic oil-water separator
- Patented S.T.P.M oil-water coalescing module
- Patented anti-twist floating skimmer
- UV-135 UV sterilizer
Benefits
- Physical separation of tramp oil; coolant concentration is unchanged
- Air-driven, so there is no electrical leakage risk on the floor
- Separated waste oil holds little water, giving better recovery conditions
- Float skimmer follows the liquid level, working down to 5 cm

Sludge & oil-water separation
Continuous vacuum filtration intercepts settled sludge, so the CNC never has to stop for tank cleaning.
Common problems
- Sediment building up at the tank bottom, taking up capacity
- Surface tramp oil and oil-water mix hard to separate
- Continuous iron chips, aluminium mud and tungsten powder
- High fluid content in metal chips lowers recovery value
Our approach
- Vacuum principle achieves high draw for continuous filtration
- FC-series self-cleaning vacuum drum raises suspended-impurity capture saturation
- Captures iron chips, aluminium mud, copper and tungsten powder in both neat and water-soluble coolant
- FCG precision filtration targets fine dust from grinding and EDM
Equipment & technology
- FC chip-recovery circulation series (FC180 / FC180 Plus / FC380)
- FC-series self-cleaning vacuum drum
- FCG-105 / FCG-105 AUTO precision filtration systems
- Japanese-imported submersible pump
Benefits
- Continuous vacuum extraction — no stopping the machine just to clean the tank
- FC series captures chips in a stainless basket that is rinsed and reused
- FCG precision filtration rated at 5μm; the cartridge is a replaceable consumable
- Chips do not pile up on the tank floor, so usable capacity is maintained

Four contaminants, four treatment paths
Air and liquid follow two different paths, and the liquid side splits again by contaminant. Below is what each path passes through and what it leaves behind. Everything is handled physically, without altering the coolant's original concentration.
What machining produces
One machine generates several things at once: atomised oil smoke, tramp oil floating on the surface, metal chips settling at the bottom of the tank, and suspended fine powder. They behave differently, so they are handled on different paths.
Air path
Atomised oil smoke and fine particulates
- Extraction at the machine
- GEP upright oil mist collector

Industries we serve
Different machining methods, different forms of pollution. Select an industry to jump to the matching solution or equipment.
01
Machine Tools
Whole machines need pollution-control equipment before shipment; turn-mill work produces oil mist and heavy chips at once.
02
CNC Precision Machining
High-speed machining atomises heavily; fine-chip contamination directly affects surface precision.
03
Aerospace Machining
Hard-to-cut titanium and aluminium alloys generate high-temp oil vapour with strict coolant-cleanliness demands.
04
Bicycle Industry
Aluminium extrusion and frame machining produce heavy aluminium mud that settles and resists dewatering.
05
Automotive & Transportation
Volume lines run continuously; coolant-change downtime is costly and needs long-life circulation.
06
Metalworking
Iron and copper powder in the coolant cause rancidity and odour, with oil build-up in the work area.
07
Precision Technology
Quartz, silicon-carbide and semiconductor grinding produce ultra-fine dust needing filtration below 5μm.
08
Heavy Industry
Large-part machining uses high fluid volumes; tramp-oil and sediment demands exceed a normal line.
Industry categories are drawn from GREEN ECO PRO's existing installation records. Actual equipment selection still depends on the on-site machining method, coolant type and fluid volume.
43 installation records
Across machine tools, precision technology, aerospace, bicycles, transportation and heavy industry. The records cover direct purchases, equipment supplied with new machines, and trial installations, so the type of engagement varies.
