The units combine an integrated motor-pump group, a preheating system, and a high-efficiency offline filter.<\/p>\n<p>The system draws oil from the tank, heats it, filters it, and returns it to the circuit, operating independently of the main system.<\/p>\n<h3>Operating Principle: Preheating and Radial Filtration<\/h3>\n<p>The unit integrates a gear pump and an electric heater with thermostat.<\/p>\n<ul>\n<li><strong>Preheating:<\/strong> Electric heating ensures that cold or high-viscosity fluids reach a viscosity suitable for filtration.<\/li>\n<li><strong>Fine Filtration:<\/strong> The oil passes through the filter element in a radial direction, preventing channel formation. Standard elements feature a filtration rating of <strong>0.5 micron<\/strong>, ensuring extremely clean oil and high dirt and water holding capacity.<\/li>\n<\/ul>\n<h3>Design Features<\/h3>\n<p>The units feature a compact design and are easy to maintain.<\/p>\n<ul>\n<li><strong>OLSH 30:<\/strong> Single-housing configuration with a 300 mm (11.81 in) long element.<\/li>\n<li><strong>OLSH 60:<\/strong> Single-housing configuration with a 600 mm (23.62 in) long element for higher capacity.<\/li>\n<\/ul>\n<p>The system is driven by an electric motor (standard three-phase 230\/400 V AC or optional single-phase versions).<\/p>\n<h3><strong>Technical Specifications and Performance<\/strong><\/h3>\n<ul>\n<li><strong>Flow rate:<\/strong> 2.1 l\/min (OLSH 30) and 4.2 l\/min (OLSH 60).<\/li>\n<li><strong>Pressure:<\/strong> Max differential pressure 6.2 bar; Max housing pressure 20 bar.<\/li>\n<li><strong>Fluid temperature:<\/strong> Max +80\u00b0C.<\/li>\n<li><strong>Connections:<\/strong> Suction G3\/8 (OLSH 30) or G1\/2 (OLSH 60); Return G1\/2.<\/li>\n<\/ul>\n<h3>SRM Filter Elements<\/h3>\n<p>The units are supplied as standard with 0.5 micron cellulose elements (Code H).<\/p>\n<p>Optionally available are inorganic glass fiber elements (1, 3, 5, 10, 20 microns) or polymer elements for water absorption (Code EA).<\/p>\n<h3>Summary technical table of the main features of the Stauff OLSH Heated Offline Filters<\/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;\">Unit Type<\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Heated Offline Filter (OLSH)<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Special Function<\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Integrated electric preheating<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Configurations<\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Single (L = 300 mm) \/ Single (L = 600 mm)<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Nominal Flow Rate<\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">2.1 l\/min (OLSH 30) \/ 4.2 l\/min (OLSH 60)<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Max Pressure (Housing \/ Diff.)<\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">20 bar (Housing) \/ 6.2 bar (Diff.)<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Standard Filtration Rating<\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">0.5 micron (Cellulose)<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Heater Capacity<\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">2 kW (tabular reference)<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Electric Motor (Std)<\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">230\/400 V AC, 50 Hz (Three-phase)<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Max Fluid Temperature<\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">+80 \u00b0C<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">Seals<\/td>\n<td style=\"border: 1px solid #ddd; padding: 8px;\">NBR (Standard), FKM (Optional)<\/td>\n<\/tr>\n<\/tbody>\n<\/table><\/div>\n","protected":false},"excerpt":{"rendered":"<p>The Stauff OLSH Heated Offline Filters are units designed for industrial hydraulic systems, featuring an integrated electric preheating system.<\/p>\n<p>This technology brings cold or high-viscosity fluids to the temperature suitable for filtration, ensuring optimal performance through the filter element (standard 0.5 micron).<\/p>\n<p>Available with 300 mm (OLSH 30) or 600 mm (OLSH 60) filter elements, they prevent channel formation and remove solid particles and water.<\/p>\n","protected":false},"featured_media":10156,"template":"","meta":[],"product_brand":[],"product_cat":[103,191,415],"product_tag":[281],"class_list":{"0":"post-10513","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-filters","7":"product_cat-stauff-filters","8":"product_cat-stauff-offline-and-bypass-filters","9":"product_tag-stauff","10":"yith_product_brand-stauff","12":"first","13":"instock","14":"shipping-taxable","15":"product-type-simple"},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v21.5 (Yoast SEO v26.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Stauff OLSH Heated Offline Filters \u2013 LubeTeam Hydraulic<\/title>\n<meta name=\"description\" content=\"Stauff OLSH Heated Offline Filters with integrated preheating.
