Genuine HVAC Part: Carrier 30GX417133E Integrated External Oil Filter – Suitable for 30HXC Screw Chillers

Genuine HVAC Part: Carrier 30GX417133E Integrated External Oil Filter – Suitable for 30HXC Screw Chillers

The 30GX417133E is an integrated, external spin-on oil filter designed specifically for Carrier 30HXC, 30HX, and 30HXY series water-cooled screw chillers. It features a fully sealed, non-disassemblable seamless steel housing containing a multi-layer pleated fiberglass filter element supported by dual-layer galvanized steel mesh, utilizing an "outside-in" flow configuration. Installed in the external oil supply line, it captures metal wear particles, rust dust, welding slag, and sludge from the POE refrigeration oil, ensuring a supply of clean lubricant to the screw rotor meshing surfaces and sliding bearings, thereby preventing particulate-induced wear on precision components.

Core Filtration Features:
1. Core Filtration Performance of the Filter Element
Features a multi-layer pleated design using imported HV glass fiber media and a high-precision (10μm) composite glass fiber layer; the filtration surface area is optimized for low-to-medium flow oil circuits, efficiently capturing micron-sized metal debris, pipeline rust, and welding residue. It offers excellent temperature resistance, utilizing oil-resistant epoxy resin bonding that prevents cracking or fiber shedding—which could contaminate the oil—during thermal cycling.
2. Dual-Layer Galvanized Carbon Steel Support Mesh
The filter media is sandwiched between inner and outer galvanized steel mesh layers that are fully welded at both ends. This structure withstands instantaneous pressure surges during oil pump start-stop cycles, preventing media collapse or flow path obstruction, thereby ensuring stable, undiminished oil supply flow.
3. Fluid Flow Characteristics
The initial pressure drop of a new filter element is less than 0.22 bar. Even under full-load operation in small-to-medium screw compressor units, the pressure drop remains extremely low, avoiding issues such as low oil pressure or system shutdowns triggered by pressure differential alarms.

Product Internal Structure and Material Composition:
1. Seamless Epoxy-Coated Steel Cylinder (Main Housing)
A seamless steel tube formed via integral roll-forming; rated for 34.5 bar pressure to withstand the high-pressure oil circuit conditions of screw compressor units, with roll-sealed end caps.
2. Outer Galvanized Protective Steel Mesh
Acts as a primary coarse filter, blocking large welding slag and rust particles from directly impacting the fiberglass filter media, thereby extending the filter element’s service life.
3. Multi-layer Pleated Fiberglass Filter Element (Filtration Core)
Features an ultra-fine pleated fiberglass filtration layer that purifies refrigeration oil and removes all hard impurities, protecting screw rotors and sliding bearings from particle-induced scoring.
4. Inner Galvanized Support Cylinder
A central support framework that withstands negative pressure in the oil circuit, preventing the filter media from collapsing inward and blocking the oil flow, while stabilizing the oil pump’s supply flow rate.
5. Integrated Viton (Fluororubber) Gaskets at Both Ends
Prevents high-pressure oil leakage at the threaded connections and stops contaminated oil from bypassing the filter element.
