Dusty Construction Sites? Anti-Clogging Oil Filter Elements for Excavators & Loaders
January 1, 2023
Construction machinery faces heavy contamination from dust ingress, seal wear, tank breathing, and metal abrasion. Customers often report fast clogging, slow hydraulics, rising return pressure, or spool sticking.
Two priorities for Oil Filter Elements here are surface area and anti-collapse design. Choose deep glass-fiber pleated media with large filtration area; dirt-holding improves by ~40% over standard paper. For main return lines, 10–25 μmelements balance flow and protection; add 10 μm fine filters before sensitive valve blocks. With heavy shock loads, use reinforced metal cores or mesh-supported composites to prevent collapse.
System tactics help: upgrade tank breathers, add magnetic traps on return ports, and monitor cleanliness (target ≤ ISO 18/16/13). Replace by ΔP trend and oil sampling, not fixed hours. If ΔP hits limits too quickly, investigate root sources like tank rust flakes or worn seals.
