Fuel Oil Filter · Fuel Oil Treatment
The Boll & Kirch 6.46 Auto Filter is an automatic back‑flush fuel oil filter with integrated differential pressure monitoring, designed to continuously clean fuel oil and reduce manual maintenance. As a Fuel Oil Filter, it is normally installed in the fuel transfer, conditioning or booster system upstream of engines or boilers. In that role, its primary purpose is to filter, heat, transfer or condition fuel before it reaches the final consumer. Filters, heaters, pumps and separators perform different stages of fuel treatment and must be operated according to the actual fuel grade and installed system. Capacity: 5-50 m³/h, 25-50 µm. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
