The distinctive feature of these components lies in the use of a special fabric and a dedicated format (<em>special format<\/em>) developed by STAUFF to ensure maximum operational safety and optimal engine protection.<\/p>\n<p>A key design element is the use of molded plastic end caps. This construction choice is not only structural but also intended to allow easy interconnection between components. Thanks to this molded end-cap system, maintenance operations are optimized: installation and removal of the filter elements can be carried out quickly and safely, reducing machine downtime. While the standard configuration uses plastic filter media, versions with stainless steel mesh are available on request for specific requirements.<\/p>\n<h3><strong>Dimensional Specifications and Filtration Capacity<\/strong><\/h3>\n<p>The dimensional range of the SFK Series is designed to meet various installation needs. The elements are available in two main lengths:<\/p>\n<ul>\n<li><strong>320 mm<\/strong> (12.59 inches).<\/li>\n<li><strong>445 mm<\/strong> (17.52 inches).<\/li>\n<\/ul>\n<p>The element diameter also varies within a defined range, from a minimum of 19 mm (0.75 inches) to a maximum of 33 mm (1.29 inches), ensuring compatibility with different system configurations.<\/p>\n<p>In terms of filtration performance, SFK pre-filters provide micron ratings calibrated for effective coarse pre-filtration, which is essential for engine protection. The standard options available are:<\/p>\n<ul>\n<li><strong>25 \u00b5m<\/strong>.<\/li>\n<li><strong>31 \u00b5m<\/strong>.<\/li>\n<\/ul>\n<p>This combination of dimensional flexibility and filtration capability makes the SFK-320 and SFK-445 Series a targeted solution for users requiring reliability and ease of maintenance in engine applications.<\/p>\n<h3>Technical summary table of the main features of the Plastic Engine Pre-Filters \u2013 SFK-320 and SFK-445 Series.<\/h3>\n<div style=\"width: 100%; overflow-x: auto;\">\n<table style=\"width: 100%; border-collapse: collapse;\">\n<thead>\n<tr>\n<th style=\"border: 1px solid #ddd; padding: 8px; text-align: left; background-color: #f2f2f2;\">Feature<\/th>\n<th style=\"border: 1px solid #ddd; padding: 8px; text-align: left; background-color: #f2f2f2;\">Value<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Product Series<\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">SFK-320 and SFK-445<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Function<\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Engine pre-filter<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Standard Filter Media<\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Plastic (with special fabric)<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Optional Filter Media<\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Stainless steel mesh (on request)<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Available Lengths<\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">320 mm (12.59 in) \/ 445 mm (17.52 in)<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Diameter Range<\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">19 mm to 33 mm (0.75 in \u2026 1.29 in)<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Filtration Rating (Micron Rating)<\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">25 \u00b5m or 31 \u00b5m<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">End Cap Material<\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Molded plastic<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>The <strong>Plastic Engine Pre-Filters \u2013 SFK-320 and SFK-445 Series<\/strong> are specifically designed to ensure maximum safety and optimal engine protection.
