Recommended filters for controlling both air and water pollution.

• Made of 100% borosilicate glass fibres without binders.

• Glass fibre filters absorb the finest particles down to 1 μm from liquids, in air, gases and even aerosols with 0.3 –0.5 μm are separated.

• The large surface area (about 2m²/g) provides an outstanding retention capacity.

• Extremely low content in metals.

• Chemical stability: It keeps all its properties in contact with acid solutions (except hydrofluoric acid) and/or basic solutions at moderate concentrations.

• Stability at high temperatures: It keeps its properties up to 500 ºC.

• High flow speed and high permeability to air.

These types are available as filter circles with the following sizes (in mm):

25 – 37 – 47 – 50 - 55 – 70 – 90 - 110 – 125 – 142 – 150.

Other sizes, sheets, rolls and special cuts are available on request.
