What buyers ask us before the first order.

Every note on this page started as a real inquiry: how to specify an element, which medium fits a duty, why a cartridge failed early, what a drawing review takes. Written by the engineers who quote the work, not by a marketing desk.

  • Written from live inquiries
  • How-to, diagnosis and buying — no press releases
  • Drawing review 3–5 working days

What We Write About

Four lines, all of them taken from live inquiries

If the question you arrived with is not written up yet, put it to the desk directly — that is how most of these notes start.

  • Specifying an element

    The inputs an element maker needs before it can quote, and what each one actually changes in the design.

  • Choosing the medium

    Woven wire mesh, sintered wire mesh or sintered fiber felt: which one suits the duty, and where each one gives up.

  • Replacement and cross-reference

    Reading an OEM part number, matching an element that is already qualified, and what a copy has to prove before it goes on the line.

  • Buying, lead time and MOQ

    What a drawing review takes, what a sample order costs, and how production lead time is actually built.

Asked at the Desk

Six questions that arrive most often

Short answers here. The linked page carries the detail, and the desk answers anything that is not written up yet.

  • What do you need from me before you can quote?

    Temperature, medium, pressure, contaminant, the rating you need, flow — and the drawing, if one exists. That is seven inputs, and each of them changes the design rather than just the price.

    What we ask for
  • Which medium fits my duty — mesh or felt?

    Sintered fiber felt covers 0.5 – 50 μm and holds the most contaminant; sintered wire mesh covers 2 – 200 μm and keeps its pore size under high differential pressure. Woven mesh is the medium we weave ourselves.

    Compare the three media
  • Will a replacement element hold the same rating as the brand it replaces?

    It is measured rather than asserted: bubble point, air permeability and precision are tested on every batch, and the record travels with the dispatch.

    How we test a batch
  • Can you work from a part number or a used sample?

    Yes. A part number, a drawing or a used element is enough to start, and the copy is confirmed with a sample before the first production run.

    Start from a sample
  • Do you hold the certification my supplier audit asks for?

    We hold ISO 9001 and every dispatch carries its batch test record. Material certificates and project-specific certification are confirmed per inquiry — and if an audit needs something we do not hold, we say so at the first call.

    Manufacturing and inspection
  • What is the smallest order you take?

    MOQ runs from a few pieces to a few dozen, and a sample order is a few pieces. Samples ship in 20 – 30 days; production runs 30 – 60 days.

    MOQ and lead time

Your question is probably not written up yet.

Send the duty — temperature, medium, pressure and flow — and an engineer answers it. If it turns out to be a question other buyers share, it becomes the next note on this page.
