Filter straight oil
back to new condition.
The S.O.F. straight oil filter purifies neat industrial oils by removing solids and water associated with corrosive and abrasive wear. A field installation reduced new-oil purchases by more than half, and purification can extend oil service life indefinitely.
Oil purification that reduces new-oil demand
The S.O.F. unit removes solid particulates and moisture from straight industrial oils, controlling the acid, water, and silt contamination that degrades a fluid. Purified oil returns to new condition or better, and its working life can be extended indefinitely.
Bulk solids, fine solids, then water
Dirty oil passes through staged filtration: a bag for the bulk load, a cartridge for fine solids, and a moisture-removal stage that reduces bulk and trace water to 10 ppm. The treated oil returns to service after filtration.
Bag filter
Captures bulk solids first, reducing the coarse-solids load on the downstream cartridge.
Cartridge filter
Polishes the oil, removing fine solids down to 3 micron.
Moisture removal
Removes bulk and trace water to 10 ppm, reducing moisture that contributes to corrosion.
Clean oil out, to new condition or better. The example above shows a portable bag and cartridge canister configuration; the staging is matched to your fluid and contamination at quotation.
System functions and operating results
Supported straight-oil and industrial-fluid applications
The S.O.F. line purifies neat oils across a plant, from the machining floor to the hydraulics to the heat-treat shop.

S.O.F. is designed for straight, neat, and synthetic oils, not water-based coolant. Use C.R.O.S.S. for coolant recycling and T.O.S.S. for tramp-oil separation.
Oil back to new condition or better
The illustrated S.O.F. configuration removes bulk solids on the bag, fine solids to 3 micron on the cartridge, and trace moisture down to 10 ppm, the contamination that drives the corrosive and abrasive wear behind most equipment failures.
Purified oil performs like new and its working life can be extended indefinitely. An EdjeTech engineer confirms oil compatibility and system configuration during the application review.
Matched to your oil and contamination
The S.O.F. line is built to the fluid and the contamination it carries. The staging, micron ratings, and format are set with an engineer.
Portable canister unit
The portable bag and cartridge canister unit: bulk solids on the bag, fine solids to 3 micron on the cartridge, with moisture removal down to 10 ppm to rejuvenate the oil.
Sized to your fluid
Micron ratings, water-removal stage, flow, and portable or fixed format are matched to the oil and its contamination profile.
Configuration is application-specific. Hydraulic-oil reclamation and EDM-oil polishing require different filtration stages. The portable build uses a TEFC motor, self-priming positive-displacement pump, and NEMA 4 electrical enclosure with 120 VAC single-phase power; 240 VAC and Class I, Division I explosion-rated configurations are available.
Product and ownership questions
- 01
Which oils can it filter?
Compatible fluids include hydraulic, gear, turbine, compressor, cutting, drawing, EDM, quench, lube, engine, transformer, and rust-preventing oils, plus ATF, brake fluid, synthetic oils, and fuels. An engineer can evaluate oils outside this list because the filtration stages are selected for the fluid.
See the full fluid list → - 02
Does it remove water as well as solids?
Yes. It removes bulk solids and fine solids down to 3 microns, plus bulk and trace water down to 10 ppm. Water removal reduces corrosion and acid-formation risk, while solids removal addresses abrasive wear.
- 03
Will filtered oil really perform like new?
Purified oil returns to new condition or better, and its working life can be extended indefinitely. The right media for the contaminant is what makes that repeatable.
- 04
Is this for my coolant?
No. The S.O.F. line is for straight, neat, and synthetic oils, rather than water-based coolant. For coolant recycling, see C.R.O.S.S.; for tramp oil in coolant, see T.O.S.S.
See C.R.O.S.S. → - 05
How is the correct configuration selected?
Provide the oil type, contamination profile, required flow, and installation preference. An engineer selects the filtration stages and format and confirms application fit before quotation.

What routine maintenance is required?
Routine ownership care centers on condition-based filter-element replacement, accessible strainer cleaning, and hose inspection. The self-priming, self-lubricating pump requires no scheduled maintenance.
