Ceramic Fiber Filter Products

The deciding question is whether you need NOx control. If your emission permit covers particulate only, the standard ceramic fiber filter tube is the right product — same 1 μm filtration precision, >99.9% dust removal, and 1,100°C continuous rating at lower cost. If you must also reduce NOx, the catalytic version integrates a V₂O₅-TiO₂ catalyst layer into the tube wall, achieving 85–95% DeNOx within a 250–400°C reaction window — replacing a separate SCR reactor. One important check: for the catalytic version, your normal operating temperature must sit inside that 250–400°C window. Outside it, the catalyst does not react and you are paying for capability you cannot use. Tell us your permit limits and operating temperature and we will point you to the right product.

Standard diameters run from Φ60 to Φ200 mm with lengths up to 4 m. Dimensional tolerances are ±3 mm on diameter and ±10 mm on length. Beyond the standard range, customization of diameter, length, flange interface, and mounting hardware is routine work for us — we are the manufacturer, not a reseller, so non-standard dimensions do not involve a middleman’s markup or a tooling surcharge surprise. What we will not do is promise a dimension outside what the forming process can hold; if your requirement is at the edge of feasibility we will tell you and propose the closest workable design. Send a drawing or sketch with your inquiry — that is the fastest route to a firm answer and a quotation.

MOQ depends on specification — standard sizes start from a small trial quantity because we would rather you validate performance in your own system before committing to volume. For catalytic tubes, MOQ is somewhat higher because each production run involves catalyst coating and curing. Lead time for standard products is typically quoted in weeks; customized dimensions add tooling and first-article inspection time. Sea freight to major ports worldwide is standard practice for us — we have shipped to 30+ countries and handle export packaging, fumigation-free crates, and documentation (commercial invoice, packing list, certificate of origin, and test reports). State your destination port in the inquiry and the quotation will include a realistic delivery window.

Ceramic elements are rigid and must be protected from point impact, so packaging is engineered accordingly: each tube is individually sleeved, separated with molded end caps and dividers, and packed in fumigation-free export crates sized for container loading. We have shipped this product by sea to 30+ countries for over a decade; transit damage claims are rare and, when they occur, are handled with replacement shipment. On arrival, inspect crates before signing the delivery receipt and photograph any external damage — that protects your claim. Handling guidance ships with every order: no throwing, no stacking beyond the marked limit, and store dry before installation.

Yes. We provide samples of standard-specification tubes so you can verify dimensions, fit, and material quality before committing — and we genuinely encourage it, because a filter that fits your tube sheet perfectly is the cheapest insurance in this industry. For catalytic versions, sample availability depends on current production runs; tell us your target specification and we will confirm what we can ship and at what cost. Samples ship by international express with tracking. When you are ready to move from sample to order, the sample fee handling and any volume pricing are settled transparently in the quotation.

Yes, and it comes from the engineers who make the product, not a call center. Every order ships with installation and handling instructions covering tube sheet alignment, sealing, torque guidance for mounting hardware, and the pre-coating procedure where your fuel or dust requires it. For system-level projects we support commissioning remotely — pulse pressure tuning, cleaning cycle setup, and the first-week operating checklist. If something underperforms in service, our first step is always a data review (operating temperature, velocity, pulse pressure, gas chemistry) because most field issues are specification or operating issues that can be corrected without replacing hardware. Support is available in English by email with technical replies, typically within one working day.
