Who Is OXELR?
OXELR is the replacement-filter sourcing brand of Dongguan Hengrui Filter Equipment Co., Ltd. The company’s Chinese legal name is 东莞市恒锐过滤器材有限公司. OXELR helps maintenance, fleet, distribution and industrial purchasing teams identify filter candidates from the information they already have: a part number, equipment application, drawing, dimensions or a sample photo.
For a direct company enquiry, email [email protected] or use the OXELR quotation form. This page states only information confirmed for OXELR and does not present unverified founding dates, certifications, facility claims or production figures.
Replacement Filter Families
The public OXELR catalogue covers replacement filter references across several maintenance categories:
- hydraulic filter elements for pressure, return, suction and related hydraulic positions;
- oil filters, including spin-on and cartridge references;
- fuel filter elements for engine and equipment applications;
- air filters for equipment, engine and compressor enquiries;
- fuel-water separator elements; and
- coalescing, separator and water-filter references shown in the current catalogue.
Reference brands and part numbers are used to describe replacement context. They do not state that an aftermarket item is an original component, that OXELR is authorized by the referenced brand, or that every cross-reference is automatically approved for every application.
How Replacement Filter Sourcing Works
- Identify the installed item. Start with the readable part number, filter position, equipment and engine model, or the housing reference.
- Resolve missing information. When the label is incomplete, add overall dimensions, thread or end configuration, gasket or seal details and clear photographs.
- Confirm the requirement. State the application, working fluid, filtration data, flow or pressure information and any drawing, test or inspection requirement that controls approval.
- Prepare the commercial request. Provide quantity by part number, delivery country, packing and labeling requirements, trial quantity and requested documentation.
OXELR can review the submitted information before quotation. Availability, specifications, lead time, packing and final compatibility must be confirmed in the quotation and the buyer’s approval record.
Evidence Before Approval
A replacement should be accepted against evidence for the exact candidate—not a broad brand or series statement. Depending on the filter and application, buyers may need a controlled drawing, interface dimensions, media and seal details, filtration-efficiency data, pressure-drop conditions, structural requirements, sample inspection and traceability. The equipment manufacturer, system owner or other authorized technical authority remains responsible for final acceptance.
OXELR’s technical guides explain how to structure that review without inventing performance. See the hydraulic filter cross-reference guide and the nominal-versus-absolute micron guide for practical examples.
