MELTBLOWN Filters by Profiltr: High-Efficiency Filtration Solutions

Profiltr’s MELTBLOWN filters, including the PROVent A Series, are premium-grade polypropylene cartridges engineered for outstanding liquid filtration. Manufactured using advanced melt-blown technology, they deliver exceptional particle retention efficiency of up to 99.98% (β=5000), making them ideal for demanding industrial, food, beverage, and pharmaceutical applications.

Key Advantages

Multi-layer graded density structure – ensures optimal contaminant capture while maintaining low pressure drop, resulting in extended service life and improved performance.

Pure 100% polypropylene construction – provides excellent chemical resistance, full FDA compliance for food and pharmaceutical use, and guarantees zero additives such as oils or silicones.

Versatile configurations – available in micron ratings from 0.5 to 120 μm, lengths from 5 to 60 inches, with options for polypropylene or stainless steel cores, as well as various end caps and O-rings.

Melt-Blown Technology

The melt-blown process involves extruding molten polymer into high-velocity hot air streams, forming ultra-fine fibers that bond into a three-dimensional matrix. This structure offers superior porosity, low flow resistance, high dirt-holding capacity, and excellent mechanical stability—even under differential pressures up to 10 bar.

Applications

These filters are perfectly suited for pre-filtration in RO/DI systems, chemical processing, food and beverage production (including water, juices, and beer), pharmaceuticals, and oil & gas operations. They effectively handle a wide range of fluids, including water, acids, bases, and fuels, with a maximum operating temperature of 80°C (up to 120°C for short-term exposure).
