In industrial procurement, requesting a quote for filter cartridges might seem straightforward. However, incomplete information often leads to prolonged communication, inaccurate pricing, and potential delays for your projects. A professional and detailed inquiry not only saves you time but also enables suppliers to provide the most suitable product and a competitive price.
This guide will help you structure your inquiry based on your cartridge type to ensure a fast and efficient quotation process.
The information you need to provide depends entirely on whether you need a standard, off-the-shelf cartridge or a custom-designed one.
A. For Universal Standard Cartridges
If you are looking for a common, universal model (often a direct replacement for brands like Pall, Parker, HYDAC, or Donaldson), the process is simple.
You Need to Provide:
Clear OEM Model Number: The exact manufacturer and model number is crucial. (e.g., "Pall HC8900FKN39H" or "Parker 818445Q").
Required Quantity: The initial and potential annual volume. (e.g., "100 pcs for initial order").
Example Inquiry:
"Dear Team,
Please provide a quotation for the following standard filter cartridges:
Model: Pall HC8900FKN39H
Quantity: 100 pcsPlease include lead time, pricing including tax, and shipping options.
Thank you."

B. For Non-Standard or Custom Cartridges
This is where detailed information is critical. If your cartridge has no universal number or is built for a specific machine, providing comprehensive technical data is essential for an accurate quote.
Essential Information You Must Provide:
Physical Dimensions:
Outer Diameter (OD): The diameter at the widest point of the cartridge.
Inner Diameter (ID): The diameter of the center hole.
Length/Height: The total height/length of the cartridge.
(Please use consistent units: millimeters [mm] or inches [in]).
Interface/Connection Type:
Threads: Specify male or female threads and the exact thread specification (e.g., "M30x1.5", "3/4"-16UNF", "G1"").
Flat Ends: If the end caps are plain without threads, state this clearly.
Filter Media Material:
Specify the material, e.g., Polypropylene (PP), Polyester, Glass Fiber, Stainless Steel Wire Mesh, Sintered Stainless Steel.
Filtration Rating:
State the micron rating (e.g., 1, 5, 10, 25 micron) and specify whether it is an Absolute or Nominal rating.
Core and End Caps:
Core Material: e.g., Stainless Steel, Polypropylene, Galvanized Steel.
End Cap Material: e.g., Polypropylene, Stainless Steel, Galvanized Carbon Steel.
Seals/Gaskets:
Material and Location: e.g., "NBR O-ring on the end face," "FKM seal on the side."
Highly Recommended Supplementary Information:
Clear Photographs/Drawings: Photos from multiple angles are invaluable. Close-ups of the ends and any labels are extremely helpful. An engineering drawing is ideal.
Application Details: What fluid does it filter? (e.g., Hydraulic Oil, Water, Process Chemical, Compressed Air). Also, specify operating temperature and pressure.
Provide a Sample: For high-volume orders or critical applications, sending a physical sample is the most reliable way to ensure a perfect match.
