Material Selection and Application Focus

Our filters are crafted from a range of durable materials including plastic, galvanized steel, stainless steel, and aluminum, suitable for diverse industrial environments. Threaded flanges are offered in sizes RD60, RD72, RD73, RD100, and RD200.

Primarily focused on air and dust filtration, we use materials like polyester (our most popular), cellulose blends, nano-layered polyester, and flame-retardant options. For environments with explosive dust, our antistatic versions are essential. Additionally, all polyester filters can be treated with antistatic, PTFE coating, or PTFE membrane.

We also provide a comprehensive range of filter bags in these materials, catering to replacement filters for OEM dust collection systems and other known brands.
