In the highly competitive grease manufacturing industry, stringent quality control is paramount. Producers must ensure their finished lubricants are free from detrimental impurities, including large particles, unreacted raw materials, grease clumps, and foreign contaminants such as iron particles, dust, and dirt. Achieving this level of purity is critical for product performance, longevity, and ultimately, market trust and compliance.
The unique rheological properties of grease—behaving as a non-Newtonian fluid that flows only under shear—present significant filtration challenges. This characteristic often leads to filter clogging, necessitating filtration under specific high-pressure and elevated temperature conditions. Furthermore, the subsequent cleaning of fouled filters is notoriously difficult, time-consuming, and mandates taking production lines offline, resulting in costly downtime and reduced throughput.
Multifab™ has developed an innovative and robust filtration solution specifically engineered for high-pressure grease applications: the Multifab™ Grease Filter.
This advanced system efficiently removes all particles greater than 50 microns from pressurized grease streams. This precise filtration enables manufacturers to consistently achieve the coveted NLGI “Clean Grease” rating and, with continued integration, the “Super Clean Grease” rating for their products, aligning directly with critical industry particle size analysis standards such as DIN 51813 and DIN 51825. For the most demanding purity requirements, the Multifab™ Grease Filter can be seamlessly integrated with an additional Multifab™ super fine filtration unit to achieve an “Ultra Clean Grease” rating.
A hallmark feature is its self-cleaning capability, facilitated by a pneumatically operated cleaning ram. This system allows for efficient filter cleaning in situ between grease batches or at predetermined frequencies, virtually eliminating manual intervention and significantly reducing maintenance-related downtime. The filter can also be effectively cleaned with hot oil, providing exceptional versatility for processing various grease types, grades, and formulations without cross-contamination. Constructed from high-grade stainless steel, the Multifab™ Grease Filter is inherently durable, easy to sanitize, and compatible with food-grade and coloured greases. Its robust design ensures reliable performance even under high operating pressures, with custom-engineered filters available to meet unique application specifications.
Implementation of the Multifab™ Grease Filter delivers measurable operational and quality advantages:
Guaranteed Purity: Consistent removal of particles down to 50 microns and below, ensuring compliance with stringent particle size standards like DIN 51813 and DIN 51825, and enabling NLGI “Clean Grease,” “Super Clean Grease,” and “Ultra Clean Grease” classifications.
Optimized Uptime: The self-cleaning pneumatic ram significantly reduces manual cleaning cycles and filter changeouts, leading to substantial reductions in production downtime and increased throughput.
Enhanced Operational Efficiency: Automated cleaning between batches minimizes operator intervention, improving human power utilization and overall plant productivity.
Cost Efficiency: Reduced product rework and waste due to contamination result in tangible savings in raw materials and processing costs.
Production Versatility: Hot oil cleaning enables rapid changeovers between diverse grease formulations, maximizing manufacturing flexibility and asset utilization.
Superior Product Consistency: Ensures uniform product quality batch-to-batch, enhancing brand reputation and customer satisfaction.
