KEY TAKEAWAY
Specify the cartridge's dimensions, end fitting, material and rating together; a micron number alone is incomplete.
Identify the cartridge and its housing
Send photographs of the housing label, installed cartridge and both ends of the element. Include measured length and diameter with units. An approximate length can be insufficient where end fittings or sealing surfaces differ.
For a repeat order, retain the original product code and packaging information. For an alternative, ask the supplier to confirm compatibility with the housing and operating conditions before shipment.
Define the filtration requirement
State whether the element is for sediment removal, a specified carbon duty or another defined process. Give the required flow, operating pressure and temperature, and describe the feed water. Cartridge material and seal material need to suit the application.
Ask whether the micron rating is nominal or absolute and what test basis supports it. These descriptions should not be assumed equivalent across different product families or suppliers.
Plan stock around actual operation
Estimate usage from service records and operating conditions. Record pressure changes and cartridge change-outs so future orders are based on evidence. A replacement schedule should follow the equipment instructions and site performance.
- Cartridge code, dimensions and end-fitting photographs
- Media, seal material and filtration rating
- Flow, pressure, temperature and housing details
- Quantity per pack and required order quantity
- Destination, packing and local import requirements
Make the export order easy to check
Ask for the supplied description and quantity to appear consistently on the quotation and packing list. Confirm labels and part codes before dispatch, particularly when an order contains multiple cartridge types.
Aqua Best offers cartridge and housing enquiries for African distributors and project operators. Include the destination country and exact application so the quotation can distinguish confirmed replacements from proposed alternatives.
