Oil Purification Systems
Oil Purification Systems for Hydraulic, Turbine & Lubrication Equipment
Oil Purification Systems play a vital role in maintaining the efficiency and reliability of hydraulic, turbine, and lubrication equipment across industries.
Our industrial oil purification solutions are designed to remove contaminants that degrade oil quality and damage critical components. Using an advanced oil filtration system, we ensure effective hydraulic oil cleaning by eliminating solid particles, water, and air entrainment. The process also focuses on moisture & sludge removal, extending oil life and reducing unplanned downtime. By keeping oil clean and dry, these systems help improve equipment performance, lower maintenance costs, and enhance overall operational safety.
Oil purification systems and particulate/oil removal systems are important for keeping products in good condition and should be used in every fluid application. We offer online and offline filtration services, specialized in contamination control and extending equipment life.
At Minimac Systems, we understand the need for dependable and long-lasting systems, and we offer a range of standard or custom-built industrial oil purification systems. Our choice of systems depends on the specific needs of each application, and we use the right technologies to create affordable solutions for removing contaminants from lubricating oils. We are trusted across India, the UAE, Saudi Arabia, and Oman industrial sectors for giving effective products and services.
Why Is Purification Essential?
During normal operation, lubrication and hydraulic systems generate fine metallic wear particles—often smaller than 5 microns—that continuously circulate within the oil. These abrasive contaminants combine with surface wear and are responsible for nearly 50% of machine failures. If not removed, they can lodge within tight dynamic tolerances such as bearings, valves, and pumps, accelerating wear and causing premature component damage.
Effective oil purification in accordance with ISO 4406 Cleanliness Codes and NAS 1638 contamination levels removes these microscopic particles while controlling oxidation and varnish formation. Maintaining clean, dry oil helps prevent sticky deposits, improves equipment reliability, extends service life, and significantly reduces maintenance downtime.
How Our Oil Purification Systems Work
The FS Series Oil Filtration System is a bypass filtration skid designed for both online and offline operation. This multi-stage oil filtration setup allows oil to be continuously purified without interrupting equipment operation, ensuring consistent performance and extended oil life.
Stage 1 – Large Particle Removal (149 µm)
The purification process begins with a suction line strainer rated at 149 µm. This stage captures large solid contaminants and debris, protecting downstream components and preventing premature filter loading.
Stage 2 – Fine Filtration (3 µm)
After coarse filtration, the oil passes through high-efficiency stage filters using pleated fibreglass media with filtration ratings down to 3 µm. This fine filtration stage removes microscopic particles, sludge, and oxidation by-products.
Gear-Type Pump Operation
A robust gear-type monobloc pump maintains consistent flow and pressure throughout the filtration cycle, ensuring reliable contaminant removal across all operating conditions.
Safety Controls & Monitoring
The system is equipped with dry-run protection, overload safeguards, and visual or electrical clogging indicators. These safety controls support continuous monitoring, timely filter replacement, and safe, uninterrupted operation.

Frequently Asked Questions
Q1: What are the methods of oil purification?
Oil purification methods include centrifugation (separating contaminants using centrifugal force), filtration (removing solid particles), vacuum dehydration (extracting water and gases), and adsorption (using materials like activated carbon to remove impurities).
Q2: What are the three basic types of oil filter systems?
The three main oil filter systems are mechanical filtration (physical barriers to trap particles), absorbent filtration (using materials to absorb contaminants), and centrifugal filtration (using centrifugal force to separate impurities).
Q3: What are the 4 methods of filtration?
The four common filtration methods are surface filtration (traps particles on the surface), depth filtration (captures particles inside the filter media), absorption filtration (uses absorbent materials like activated carbon), and vacuum filtration (speeds up filtration by applying a vacuum).
Q4: What is the oil purification unit?
An oil purification unit is a system designed to remove contaminants from used oil. It typically includes filters, centrifuges, and sometimes vacuum dehydration to ensure the oil is clean and ready for reuse.
Q5: How does the oil filtration machine work?
An oil filtration machine works by circulating the oil through filters and other separation systems like centrifuges to remove impurities, water, and particles, improving the oil's quality for reuse.
