Hydraulic Filters

Baldwin hydraulic filters mean pure performance, system protection and hours of trouble-free hydraulic system operation. Baldwin hydraulic filters mean pure performance, system protection and hours of trouble-free hydraulic system operation. Baldwin Filters utilizes two types of filtration media: Cellulose Media — The original and most common media used in hydraulic fluid filtration is made of natural fibers. These twisted fibers are large and irregular – creating more resistance to flow or pressure drop. This causes larger contaminant particles to become concentrated on the surface of the media, increasing restriction and limiting holding capacity. Although cellulose media comes in many efficiency grades, most cellulose hydraulic and transmission filters range from 15 to 40 microns. Synthetic Media — The applications using synthetic media have grown rapidly since the late 1970s. Synthetic media is the choice in higher pressure, heavy-duty mobile hydraulic and transmission applications. These man-made glass fibers are uniform in size and shape. Their aerodynamic characteristics present the least possible resistance to flow, while removing contaminants from fluid. Synthetic media elements may cost slightly more, but offer significant performance advantages. These advantages include: Lower restriction especially during cold start situations Improved efficiency (at smaller micron sizes) to protect sensitive controls Extended equipment life.
