Description
CNC lathe sumps accumulate sharp metal shavings submerged in thick cutting oil emulsions that destroy conventional vacuums. The Nilfisk ECO-OIL 13N1M 8 Gallon chips and oil recovery unit separates swarf from cutting fluids using an internal mesh basket. Its heavy steel construction tops 150 pounds, preventing solo transport between machine rows without smooth concrete aisles.
Heavy-gauge industrial sheet steel forms the 48 Gallon fluid basin and the removable 8 Gallon internal chip basket. An internal mechanical float shutoff terminates suction when fluid capacity peaks, preventing oil ingress into the motor stack. The single-phase bypass motor isolates electrical windings from petroleum mist through dedicated external cooling tracts. Neoprene perimeter gaskets seal the collection chamber against high static vacuum pressures, preventing fluid vapor leaks across shop bays.
Coolant Swarf Separation Matrix
Machine shop technicians run this specialized extractor to clean lathe basins, milling tables, and grinding fluid sumps. The mechanical sieve separates chips from liquid for fluid recycling and scrap disposal.
- Removable 8 Gallon perforated steel basket strains sharp metal chips out of incoming coolant streams
- 48 Gallon heavy-gauge steel collection drum stores high fluid volumes for machine tool sumps
- Single-phase industrial bypass motor generates high water lift to pull thick petroleum slurries
- Mechanical float shutoff valve prevents liquid overflow into the motor compartment
- Rear-mounted drain valve empties filtered coolants straight back into machine reservoirs
- Heavy-duty steel cart with industrial casters supports full fluid payloads across shop floors
- Oil-resistant polyurethane hose prevents wall degradation from petroleum cutting fluids and coolants
Motor Load Thermal Telemetry
Current draw pulls 12.4 Amps on 120 Volt industrial circuits under continuous heavy fluid suction. Motor dome temperatures climb 44°F above ambient room levels after 45 minutes of thick cutting fluid extraction. Exhaust port cooling air discharge stabilizes at 122°F during deep sump recovery runs. Vacuum drop measures 7-inch water lift through the 10-foot oil-resistant suction hose. Sound output meters track 72 dBA at 10 feet under free air, climbing to 76 dBA under heavy fluid drag.
Machine Shop Maintenance Rules
The wide-stance steel cart rolls steady between machinery banks, but pushing a 400-pound fluid load up ramp inclines requires mechanical tow equipment. Do not use this machine for dry drywall dust or fine masonry powder extraction, as the liquid-tuned baffle system lacks fine particulate filtration. Sucking flammable solvents, gasoline, or low-flashpoint wash spirits will cause motor brush spark explosions.
- Lift out and dump the steel chip basket before metal cuttings overflow into the fluid tank
- Flush the fluid drainage valve with clean water once per week to clear metal grit
- Check the drum perimeter seal for cutting oil softening and replace when compression drops
