Built-In Motor Shield — No Mist, No Burn-Out.
Every Depureco USA sump vacuum routes its airflow through a dedicated oil-mist cartridge before the motor. Coolant droplets and vapor are trapped, not baked onto windings or bearings, so the motor lasts longer, runs cooler, and never spits mist back into the shop. No competing sump cleaner in this class offers the same protection.
Compliance Corner
OSHA Coolant-Mist Limit (29 CFR 1910.1000)
HEPA H14 exhaust cartridge traps 99.995 % of 0.3 µm droplets, keeping aerosol below the 5 mg/m³ 8-hr TWA.

NFPA 484-2023 – Annex D
Sealed motors and conductive hoses satisfy portable-vacuum requirements for combustible metal chips.
NFPA reference
EPA Used-Oil Rule (40 CFR 279.20 b 2 ii)
On-site filtering and reuse of coolant is not classified as processing—skip hazardous-waste permits.
