Product Range and Specialties of Shijiazhuang Yitong Filter Machinery Co., Ltd

The catalogue spans polymer‑based pleated cartridges (PP, PES, PTFE), high‑flow and string‑wound designs, melt‑blown media, and metal‑based cartridges constructed from stainless steel mesh or titanium powder. In the filtration industry, pleated cartridges are typically rated by micron retention (e.g., 1‑10 µm for fine filtration) and by efficiency class such as ISO 16890 or MERV 13‑16 for air filters. Stainless steel mesh cartridges are often specified by mesh count (e.g., 100‑200 mesh) and wire diameter, while titanium‑powder cartridges may be used for high‑temperature or corrosive gas streams and are evaluated by surface area and porosity. PP filter bags are commonly supplied in standard dimensions (e.g., 500 mm × 1000 mm) and weight ratings (e.g., 30‑80 g/m²). The medium‑efficiency air filter typically meets ISO 16890 MERV 8‑11 levels, suitable for general ventilation.

Trade and Export Information - Shijiazhuang Yitong Filter Machinery Co., Ltd

China is a major exporter of industrial filtration equipment, with shipments commonly directed to Southeast Asia, the European Union, and North America. Products such as pleated cartridges and metal mesh filters fall under HS codes 8421.29 (filtering or purifying machinery and apparatus) and 8421.30 (filtering elements for liquids). Buyers usually request certifications like ISO 9001 for quality management, CE marking for EU market entry, and UL listings for North American applications. Export packaging often involves wooden crates or steel pallets, with moisture‑resistant liners for polymeric media, and the standard Incoterms used are FOB Shanghai or CIF destination port. Chinese manufacturers typically provide test reports conforming to ASTM D737 for air permeability or ISO 29463 for high‑efficiency particulate filtration.

Sourcing from Shijiazhuang Yitong Filter Machinery Co., Ltd - Buyer Guidance

When sourcing from this supplier, buyers should request material data sheets confirming polymer grades (e.g., PP‑type B, PES‑type 5) and metal specifications (e.g., 304 stainless steel, 99.9 % titanium powder). Test reports for pressure drop, flow rate, and filtration efficiency at specified face velocities are standard verification documents. It is advisable to obtain a sample cartridge to validate dimensional tolerances, pleat density, and seam integrity before placing a full order. Confirm that the supplier can provide CE or UL certification copies if the target market requires them, and verify the HS code declaration matches the product description to avoid customs delays.

What types of filter cartridges does Shijiazhuang Yitong Filter Machinery Co., Ltd offer?

The supplier lists PP pleated, PES pleated, hydrophobic PTFE pleated, high‑flow, string‑wound, melt‑blown, stainless steel mesh pleated, and titanium‑powder cartridges, covering polymer and metal media.

Are the polymer cartridges suitable for high‑temperature applications?

PP and PES cartridges are typically rated up to 120 °C, while hydrophobic PTFE cartridges can withstand temperatures up to 260 °C, making them appropriate for elevated‑temperature air or gas streams.

What standards are commonly applied to the medium‑efficiency air filter?

Medium‑efficiency air filters are usually tested to ISO 16890, achieving MERV 8‑11 ratings, which correspond to a particulate removal efficiency of 40‑70 % for 0.3‑10 µm particles.

Which certifications should a buyer request for export to the EU?

Buyers should request a CE declaration of conformity and, where applicable, an ISO 9001 quality management certificate to satisfy EU import requirements for filtration equipment.

What is the typical packaging for the PP filter bag?

PP filter bags are commonly packed in sealed poly‑film bags within a wooden crate, with each crate holding multiple bags to protect against moisture and mechanical damage during transit.

What are the common HS codes for these filtration products?

Filtration cartridges and elements are generally classified under HS 8421.29 or 8421.30, while filter housings and metal mesh components may fall under HS 7326 for other articles of iron or steel.

What minimum order quantities are typical for the stainless steel filter housing?

Suppliers often set a MOQ of one hundred units for stainless steel housings, but the exact quantity should be confirmed with the seller based on size and material thickness.

What lead time can a buyer expect for a mixed order of polymer and metal cartridges?

Lead times for polymer cartridges are usually 15‑25 working days, while metal mesh or titanium cartridges may require 30‑45 working days due to additional machining processes.
