2. Synthetic fiber bag filter, (G4 . F5 / EU4 . EU5 );

2.1 Purpose:

⭐Filtration of smaller particles in air filtration systems; pre-filtration of high-efficiency filters and air filtration of large painting lines.

13.4.2 Features:

⭐Large air volume

⭐Low resistance

⭐Sturdy structure

⭐High dust holding capacity

⭐High frequency hot melt edge sealing

3. Pleated dry filter paper;

3.1Purpose:

Filters solid or liquid particles in the air flow and acts as a flow equalizer.

13.5.2 Features:

⭐The shape design is conducive to frontal speed distribution;

⭐Weak resistance to air, maximum filtration effect;

⭐Exceeds the service life of other types of filter paper, up to six times;

⭐Continuous use for 500-600 hours, in line with DIN53438 flame retardant standard: k1;

⭐The air outlet surface is lined with glass fiber cotton or synthetic fiber cotton for better results;

⭐Framed filters can be made upon request;

3.2Principle:

Overspray collection and separation filter paper are all based on the principle of inertial separation. The load airflow is forced to change direction multiple times so that those heavier-than-air particles stick to the wall, while the air continues to move without any particular hindrance. When air passes freely through the holes, the particles are adsorbed on the pleats until the filter is saturated.
