OAS / OAH series: High Performance Filter Bags


High Performance Filter Bags feature of Tec are made of meltblown polypropylene. The hochpräzsien, ultra-fine polypropylene fibers have a large adsorption area and provide excellent results even less in the removal amounts of oil from aqueous solutions. The combination of high efficiency and oil adsorption is ideal for a wide range of applications.

applications:
● chemicals
● coatings
● discoloring agent
● cathodic dip coatings
● copper foil production
● boiler feed water
● syrups
● food & drinks and more

Features and benefits:
● Available in three different Kunststofdichtungsringen which is common to each
Bag filter housing adapt (see photos page 2).
● Depending on the customer's specifications either OAS (standard) or OAH (durable) can be used.
● Abscheideeffizienzen> 90% provide a powerful filtration (only OAH).
● Nominal Abscheideeffizienzen the OAS series.
● High dirt holding capacity and excellent adsorption of oils.
● material is free from paint-interfering substances (such as silicones, etc.) 1 *.
