Cast Aluminum Filter Base with Disposable Steel Core Filter with Drain Bolt

Cast Aluminum Filter Base with Disposable Steel Core Filter with Drain Bolt  (For Fuel Transfer Systems)

Product Overview
The HBGL-3-DR series is an advanced filter holder assembly designed for fuel transfer and industrial liquid systems. It features a disposable steel filter core with a standard filtration accuracy of 30 microns, ensuring effective impurity removal. The key difference from standard filter assemblies is the inclusion of a drain bolt, allowing easy manual drainage of water or heavy liquids that may accumulate at the bottom of the filter during operation.

The assembly is installed in an inverted position, with the drain bolt facing downward. This ensures that any water, being denser than fuel, collects at the bottom and can be safely discharged, protecting the system and improving operational safety. The filter base is made using cast aluminum technology, providing excellent structural integrity, corrosion resistance, and long-lasting durability.

This drainable disposable steel mesh filter assembly is referred to by different names in various regions, reflecting local terminology and operational practices. In North America and Europe, it is commonly known as a drainable disposable steel mesh filter assembly, a cast aluminum filter base with a drain bolt, or a fuel filter holder with a manual drain. In France, the corresponding term is support de filtre à maille acier avec boulon de vidange, while in Spain and Latin America, it is widely called base de filtro con núcleo de acero y tornillo de drenaje. In Germany, users typically search for Filterhalter mit Einweg-Stahlfilter und Ablassschraube. Across Asian markets, common names include disposable steel core filter base with drain bolt, cast aluminum drainable filter, and fuel filter assembly with manual water drain.

Despite regional differences in naming, all of these terms refer to the same functional solution: a durable cast aluminum filter base with a disposable steel core, designed with a drain feature to remove water or contaminants, ensuring reliable fuel filtration and easier maintenance for fuel dispensing and industrial fluid systems.
