Replacement cartridge filter coalescer 52-553 is a C.A. Technologies 2nd stage filter cartridge designed for air line component systems, so it serves as a key element in keeping downstream equipment performing consistently. The product is described as a REPLACEMENT CARTRIDGE FILTER/COALESCER, which means it is intended to be swapped into an existing coalescing filter body when performance starts to drop. As part of an air line Filters, Regulators, Lubricators setup, this cartridge works within that assembly to support cleaner, more stable air delivery to spray or pneumatic tools. The N/D FILTER CARTRIDGE 2ND STAGE, 52-553 designation highlights its role specifically as a second stage, which helps installers match it to the correct point in a multi-stage air treatment system.
The REPLACEMENT CARTRIDGE FILTER/COALESCER description identifies this part as the internal element that sits inside a compatible coalescing filter housing, so its job during installation is to take the place of a spent cartridge. Being labeled as a 2nd stage cartridge means it is intended for the second position in a staged air line treatment system, helping installers maintain the original filtration order when servicing equipment. As an Air Line Components item within a Filter/Regulator/Lubricator class, this cartridge fits into that broader assembly, so it supports a predictable workflow when servicing FRL stations along a line.
The product name N/D FILTER CARTRIDGE 2ND STAGE, 52-553 ties this cartridge directly to second stage duty in an air line system, so it is used downstream of initial filtration as part of staged air treatment. Because it is classified under Air Line Components and Filter/Regulator/Lubricator, it fits into FRL assemblies commonly found on shop air drops feeding spray guns or other pneumatic tools. The C.A. Technologies branding associates this cartridge with C.A. Technologies setups, so it is suited for service work where their filter/coalescer bodies are already installed. The REPLACEMENT CARTRIDGE FILTER/COALESCER description defines its role as the replaceable filtering element, so it becomes the part that technicians change during scheduled air line maintenance.
The manufacturer part number 52-553 provides a precise identifier for this REPLACEMENT CARTRIDGE FILTER/COALESCER, which matters when matching parts so the serviced unit continues to perform as originally configured. Its designation as a N/D FILTER CARTRIDGE 2ND STAGE means it is tailored to the second stage in a multi-stage setup, helping maintain consistent air preparation from point to point across a line. Being categorized as a Filter/Regulator/Lubricator class component signals that it is part of a coordinated FRL system, so using this cartridge supports a predictable approach to maintaining air quality at workstations. The link to Air Line Components directs installers toward its use within compressed air infrastructure, so it fits into regular service routines alongside regulators and lubricators in woodworking or similar shops.
The 52-553 filter cartridge is a REPLACEMENT CARTRIDGE FILTER/COALESCER, so it functions as a service element inside a compatible coalescing filter body within an air line system.
The N/D FILTER CARTRIDGE 2ND STAGE, 52-553 is identified as a second stage element, so it fits in the second position of a multi-stage air line treatment setup.
The 52-553 cartridge belongs to the Filter/Regulator/Lubricator product class, placing it within FRL assemblies that condition compressed air for tools and finishing equipment.
This C.A. Technologies filter cartridge is identified by manufacturer part number 52-553, which provides a clear reference when selecting the correct replacement element.
As an Air Line Components item, the REPLACEMENT CARTRIDGE FILTER/COALESCER works inside a filter body to help condition compressed air as it moves toward downstream equipment.
The second stage designation means this filter/coalescer cartridge is used after an initial treatment stage, helping maintain the intended sequence in a multi-stage air line system.
The REPLACEMENT CARTRIDGE FILTER/COALESCER with manufacturer part number 52-553 is specified as the N/D FILTER CARTRIDGE 2ND STAGE for C.A. Technologies air line component systems, so it aligns with service needs in Filter/Regulator/Lubricator assemblies. Its placement in the Air Line Components category ties it directly to compressed air conditioning tasks around woodworking and similar shops. When the existing second stage element is due for changeout, choosing this 52-553 cartridge maintains the defined 2nd stage role within the FRL stack and supports consistent air treatment performance across serviced stations.
