Atlas Filtri Big F Pro 256 20" x 4.5" SANIC Dual Stage UV Rainwater Filtration System with 56W Lamp (70LPM)

The Atlas Filtri Big F Pro 256 SANIC is a premium dual-stage UV water filtration system, engineered in Italy for safe, chemical-free rainwater disinfection. Combining two high-capacity 20" SANIC filter housings with a 56W UV lamp, it delivers whole-house protection at a flow rate of up to 70 litres per minute—making it ideal for medium to large households on tank, bore, or untreated rural water.

This system includes 25μm and 1μm SANIC melt-blown sediment filters, manufactured from polypropylene and enhanced with Microban® silver-ion antimicrobial technology. This not only filters out coarse and fine sediment but also helps reduce bacterial growth within the filter media—keeping the system cleaner for longer.

The final stage features a 56W low-pressure high-output (LPHO) UV disinfection chamber, built from 304 stainless steel, and protected by a lockable, weather-resistant cover. The IP54-rated controller provides a digital lamp countdown timer and audible alarm for safe and simple operation.

CARTRIDGE DETAILS

25 Micron Sediment: 

• The 25μm CPP SANIC Sediment Filter is a high-capacity pre-filter cartridge designed for use in 20" Big Blue housings. Manufactured using polypropylene melt-blown technology, it effectively captures coarse sediment such as sand, silt, and rust particles.
• Infused with silver-ion based Microban® antimicrobial technology, this filter inhibits bacterial growth on and within the media, helping to maintain system hygiene and extend service life—particularly important in rainwater or untreated water applications.

1 Micron Polyspun Fine Sediment Filter

• The 1μm CPP SANIC Sediment Filter is a fine filtration cartridge engineered for capturing microscopic sediment and organic matter, preventing fouling of UV quartz sleeves and enhancing water clarity. It is designed for use in 20" Big Blue housings
• Made from antimicrobial melt-blown polypropylene, the SANIC filter is embedded with Microban® silver-ion protection, actively suppressing microbial growth within the filter media for improved hygiene and longevity.
