About Infastaub
Infastaub GmbH is a manufacturer of industrial dust extraction systems based in Bad Homburg v.d.H. The company develops and manufactures filter systems for volume flows from 20 to 100,000 m³/h, including bag filters, cartridge filters, hose filters, lamella filters, cartridge and HEPA filters, shaker filters, silo top filters, sintered lamella and sintered cartridge filters as well as pressure-shock-resistant and explosion-protected special versions. The complete production takes place in-house in Bad Homburg in series and single-unit manufacturing with 1800–2200 systems per year; process steps are welding, degreasing and phosphating, painting, drying, assembly and final inspection. Housings and product-contacting parts are made of steel and stainless steel (e.g. 1.4301); filter media include polyester needle felt, PTFE membranes, microglass fiber web, aramid and sintered polyethylene. Customers include industries such as minerals/earth/stone, cement/lime/gypsum, steel and non-ferrous metals, food, chemistry and pharmacy, energy, recycling, glass/ceramics, plastics, nuclear technology and wood processing. In addition to consulting, dimensioning, installation and commissioning, Infastaub offers after-sales services such as maintenance, air technology and acoustic measurements, training and spare parts supply. A subsidiary in St. Petersburg (OOO Infastaub RUS) serves the Russian market.

Materials and Processes
Stainless steel 1.4301
Used for housings and product-contacting parts, e.g. in hose and silo filters for hygienic and corrosive applications.
Mild steel S235JR
Structural steel for filter housings, e.g. in cartridge filters INFA-MICRON MKR and MPR.
Sintered polyethylene (PE)
Filter medium for sintered lamella filters IJS and sintered cartridge filters IJV with clean gas values below 0.1 mg/m³.
Polyester fleece / polyester needle felt
Standard filter medium with a broad quality range, also food-compliant and antistatic.
Microglass fiber web
Filter material of classes H13–H14 according to DIN EN 1822 for HEPA filter stages in pharmaceutical and chemical applications.
PTFE (membranes, felts)
Laminated membranes and felts for high-filtration and food-grade applications.
Aramid
Filter medium for hot gas dust extraction, e.g. in the bag filter INFA-JET AJN.
