The M100 OIL coolant sump vacuum is built for CNC machine maintenance where coolant, cutting oil, metal chips, swarf, fines, and sludge collect in machine tanks and sump areas. Its 26-gal liquid capacity and mobile design make it a practical fit for recurring batch cleanouts in machine shops, precision machining cells, tool-and-die operations, and other metalworking environments.
Three independently switched by-pass motors provide up to 326 CFM airflow and 98 inH₂O vacuum, allowing operators to stage suction for the cleanup task. Recovered liquid and solids pass through a separation system designed for mixed CNC sump waste rather than ordinary dry-debris pickup.
A metal separation basket captures chips and swarf, while a washable 150 µm PPL liquid filter provides finer liquid filtration. An included oil-proof cartridge helps protect the suction unit, and a floating stop helps prevent overfilling during liquid recovery.
After collection, recovered liquid discharges manually by gravity. This makes the M100 OIL a strong fit for mobile CNC sump cleanout, coolant and cutting-oil recovery, wet chip removal, swarf separation, and sludge cleanup where a straightforward batch-discharge workflow is preferred.
Common recovered materials include water-based coolant, cutting oil, tramp oil, wet metal chips, swarf, fines, sludge, and mixed liquid/solid waste. Any decision to reuse or dispose of recovered fluid should account for coolant chemistry, contamination, process requirements, SDS guidance, and facility procedures.
Three independently switched by-pass motors let operators stage suction for the cleanup task, with up to 326 CFM airflow and 98 inH₂O vacuum in the current U.S. configuration.
The gathered liquid passes through a PPL filter with a 150µ efficiency, which enables the separation of even the tiniest solid particles. This process ensures that the filtered liquid becomes suitable for reuse. The filter is designed to be easily washed and reused. Additionally, there is an alternative disposable TNT filter with a 100µ efficiency that is also available.
A metal separation basket captures chips and swarf while a washable 150 µm PPL liquid filter provides finer separation of solids from recovered coolant or oil.
Recovered liquid drains manually by gravity from the tank, supporting a simple batch cleanout workflow without an onboard discharge pump.
Get answers about using the M100 OIL for CNC sump cleaning, coolant and cutting-oil recovery, metal chip and swarf separation, liquid discharge, model selection, and routine machine-tool maintenance.
The M100 OIL is a mobile oil-and-swarf sump vacuum designed for routine CNC machine maintenance. It is built to recover coolant or cutting oil together with metal chips, swarf, fines, sludge, and other settled contamination from machine-tool sumps and tanks.
With a 26-gallon liquid capacity, 13-gallon solids capacity, 326 CFM maximum airflow, and 98 inH₂O maximum vacuum, the M100 OIL fits machine shops that need more capacity and suction than a compact sump vacuum but do not require the larger tanks or powered liquid-discharge systems found on Depureco RAM OIL models.
Typical applications include CNC mills, lathes, machining centers, coolant tanks, chip pans, machine sumps, and other machine-side liquid-and-solid cleanup points.
Yes. Mixed liquid-and-solid recovery is one of the primary jobs of the M100 OIL. It can vacuum coolant or cutting oil containing metal chips, swarf, shavings, fines, and settled sludge during CNC sump and tank cleanout.
Larger chips and swarf are retained in the solids-separation basket while the recovered liquid moves into the lower collection area. This lets maintenance teams remove the mixed contents of a machine sump without treating the liquid and solid material as two separate cleanup jobs.
Actual performance depends on the amount and shape of the solids, fluid viscosity, hose diameter and length, tank depth, and the percentage of solids in the mixture. Long or heavily bird-nested swarf should be reviewed when sizing the vacuum and accessories.
The M100 OIL uses multiple stages of separation during sump cleanout. Larger metal chips, swarf, and shavings are retained by the internal sieve-grid basket while liquid passes into the collection tank.
Recovered liquid also passes through a washable 150 µm liquid filter that helps remove smaller suspended solids before discharge. A floating stop helps protect the vacuum when the liquid reaches its operating fill level.
This separation system makes it easier to remove the solid material independently from the recovered coolant or cutting oil instead of emptying one mixed tank of chips and liquid.
The standard M100 OIL uses gravity discharge. After the sump has been vacuumed and the recovered chips or swarf have been separated, liquid is drained from the lower collection tank through the bottom discharge connection.
The M100 OIL does not use a built-in pump for standard liquid discharge. This makes it a straightforward choice for batch sump cleaning when you can drain the recovered liquid into an appropriate container or collection point.
If the application requires powered pump-out, transferring liquid uphill, returning coolant through a hose, or vacuuming and discharging at the same time, a pump-equipped model such as the M130 OIL P or a RAM OIL configuration may be a better fit.
The M100 OIL can help recover coolant and separate metal chips, swarf, and other solids so the liquid can be evaluated for reuse instead of automatically being discarded.
Its solids basket and 150 µm liquid filtration remove bulk chips and suspended contamination, but the vacuum is not a complete coolant-treatment system. Before recovered coolant is returned to a CNC machine, its concentration, tramp-oil level, fine-particle contamination, bacteria, chemistry, and other process requirements should be checked.
Applications that require finer filtration, continuous tramp-oil removal, centrifuging, coalescing, or fluid conditioning may need additional coolant-treatment equipment.
The M70 OIL is the more compact option, while the M100 OIL is the step-up for machine shops that need greater liquid capacity, solids capacity, and pickup performance.
The M70 OIL has an 18-gallon capacity and delivers up to 230 CFM and 94 inH₂O. The M100 OIL increases liquid capacity to 26 gallons, provides 13 gallons of solids capacity, and delivers up to 326 CFM and 98 inH₂O.
Both are suited to routine oil-and-swarf recovery and use gravity liquid discharge. Choose the M70 OIL when compact size and smaller sump cleanouts are the priority. Choose the M100 OIL when larger tanks, more recovered liquid, more chips, or faster machine-side cleanup justify the additional capacity and airflow.
The main difference is the liquid-handling workflow.
The M100 OIL provides a 26-gallon liquid capacity, 13-gallon solids capacity, up to 326 CFM airflow, and gravity liquid discharge. It is a strong fit for batch CNC sump cleaning where collected coolant can be drained after the tank has been cleaned.
The M130 OIL P increases liquid capacity to 34 gallons and adds a submerged discharge pump capable of powered liquid transfer. That makes the M130 OIL P a better choice when operators need to move recovered coolant to another tank, drum, tote, or machine instead of relying on gravity drainage.
Choose based on the required cleanup and discharge process, not simply which model has the larger number.
Move from the M100 OIL to the RAM OIL family when the application requires substantially more liquid capacity, powered discharge, repeated high-volume tank cleanouts, or a more advanced coolant-transfer workflow.
For example, the RAM OIL 200 MP provides a 52-gallon liquid tank and built-in pump-out capability, while larger RAM OIL models increase recovery capacity further. These units are better suited to larger CNC sumps, multiple-machine maintenance, larger coolant volumes, and applications where recovered liquid needs to be transferred rather than drained by gravity.
The M100 OIL remains the more compact choice for routine machine-side sump cleanout when its 26-gallon liquid capacity, 13-gallon chip capacity, and gravity discharge match the job.
The two ratings describe different parts of vacuum performance.
The M100 OIL’s maximum airflow of 326 CFM represents the volume of air the vacuum can move. Higher airflow helps carry coolant, loose chips, swarf, and other debris through the hose during machine cleanup.
Its maximum vacuum of 98 inH₂O represents suction pressure, or the vacuum’s ability to pull against resistance. That becomes important when lifting liquid from a sump, recovering heavier mixtures, or working through hoses and accessories.
Neither number should be evaluated alone. Actual pickup performance also depends on hose diameter and length, tank depth, fluid viscosity, chip geometry, solids loading, and the accessory being used.
The M100 OIL may not be the best choice when the job requires powered coolant transfer, substantially more than 26 gallons of liquid capacity, continuous high-volume recovery, or cleanup of materials that have not been evaluated for compatibility.
A pump-equipped M130 OIL P or RAM OIL model may be better when recovered coolant needs to be transferred or pumped back instead of drained by gravity. Larger RAM OIL models are also better suited to higher-volume sumps and more demanding liquid-recovery cycles.
Material safety must also be considered. Do not assume a standard M100 OIL configuration is suitable for flammable liquids or vapors, hot fluids, reactive chemicals, unknown hazardous mixtures, or hazardous classified locations. Fluid chemistry, temperature, flash point, solids content, chip geometry, tank depth, hose run, discharge requirements, and operating environment should be reviewed before final equipment selection.
