Danfoss FIASS Stainless Steel Filters
FIA SS strainers are a range of angle-way and straight-way strainers in special cold-resistant stainless steel, designed for highly demanding environments where corrosion is a risk — outdoor installations, coastal atmospheres, and food plants with daily detergent treatment.
They are used ahead of automatic controls, pumps and compressors, for initial plant start-up and where permanent filtration of the refrigerant is required — reducing breakdowns and wear on plant components.
