OBERLIN Filtration Products

Oberlin Filter Company specializes in advanced automatic pressure filtration systems that remove up to 99.99% of solids down to 1 micron, producing ultra-clean filtrate (~1 mg/L) and very dry solids discharge (up to 95% dry by weight). Their core technology uses up to 40 PSI differential pressure for superior efficiency over vacuum or gravity filters, with fully automated operation requiring minimal intervention.

General Benefits of OBERLIN Filtration Units

                  

• Superior Filtration Efficiency — Removes up to 99.99% of total suspended solids, capturing particles as small as 1 micron. This delivers filtrate quality down to ~1 mg/L, far cleaner than many conventional systems (e.g., vacuum or gravity filters), leading to better process consistency and product quality.
• Extremely Dry Solids Discharge — Outputs solids as a dry cake (up to 95% dry or more), often requiring no further dewatering. This reduces disposal costs, simplifies handling, minimizes waste, and can enable reclamation or higher-value recovery of solids (e.g., in chemical or sulfur processes).
• Versatility and Space Efficiency — Handles a wide range of liquids (oil, water-based, synthetics) and applications. Systems often require 50–75% less floor space than comparable vacuum filters while providing higher throughput and efficiency.
• Environmental and Sustainability Benefits — Reduces waste, fluid consumption (up to 90% savings in some cases), and environmental impact through better recycling/reuse and lower disposal volumes.

Benefits of Fluid Filtration with OBERLIN

           

• ​​​​​Extended Equipment and Fluid Life — In metalworking, cleaner coolants extend tool life, improve surface finishes, and reduce rejects. In food processing (e.g., frying oil), it slows oil breakdown, maintains consistent color/flavor, eliminates smoking/odor, reduces free fatty acids (FFAs), and can extend oil life indefinitely with ultra-fine filtration.
• Significant Cost Savings — Uses up to 20 times less filter media (e.g., paper) than vacuum/gravity alternatives due to longer cycles and thicker filter cakes from pressure filtration. This can save 80% or more on media costs. It also extends fluid life (e.g., coolants or frying oil by 3–5x or more), reduces replenishment/disposal expenses, lowers energy use, and cuts maintenance/downtime.
• Fully Automated Operation — Runs continuously without operator intervention for cleaning or solids removal, improving reliability (up to 99% uptime), reducing labor needs, and enhancing safety by minimizing exposure to process fluids or hazards.

Types of OBERLIN Filtration Systems​.

• Standard Oberlin Pressure Filters (core product line, often designated as OPF models): These are the flagship fully automatic pressure filtration systems, available in various sizes based on filter area (e.g., from small units like 4 ft² to larger ones like 50 ft² or more).
• OLIMIN8R™ (or Olimin8r): A compact, dedicated automatic pressure filter unit designed specifically for single CNC machines or smaller setups. It removes chips and fines bypassing the chip conveyor, handles coolant volumes up to ~400 gallons and tank heights ≤27", and supports various coolants (water-soluble, semi-synthetic, full synthetic, straight oils) for machining processes like milling, turning, broaching, etc.
• Oberlin Hot Oil Filter (or Hot Oil Processing systems): A specialized variant of the pressure filter optimized for food processing applications, such as continuous or batch filtration of frying/roasting oils. It removes crumbs, fines, and free fatty acids (FFAs), extends oil life indefinitely (especially with treatment powders), and is used by major food manufacturers. Configurations include single-fryer continuous, multi-fryer batch/central systems.
