As water-based paint can consists of 10% solvent and 90% water it is obvious that a different spray booth filter is required to work effectively when compared to solvent-based paints.

Our PROPORA booth filter is a filter media especially designed for the filtration of fine, dry water-based particles. In comparison to our Profibre, the Propora is constructed of much finer fibres that are more able to filter the finest water-based paint particles far more efficiently. A special binder, gives more elasticity to these fibres, so that the initial pressure drop and consequently your energy costs are kept low. The paint holding-capacity is also substantially increased, when compared with the standard fibreglass material, by the progressive structure of the media and by a harmless binding-agent that is impregnated throughout the filtermedia.

The benefits of Propora:

  • Effective protection of the motor as well as the exhaust ducts.
  • Low pressure drop produces cost savings due to a solid stability of the filtermedia.
  • Extremely long service life, increasing your profits and reducing your down-time and waste.

Can I use Propora with solvent-based paints or just water-based?

You can use Propora with solvent-based paints and water-based paints or a mixture of both. This product will give a better level of filtration for both types of paint than the standard Profibre due to the density of the fibre however it is the better choice for water-based paints.

Can I get this material in any other sizes?

You can have the Propora in different widths, but this is only offered for orders of 10 rolls or more.

Which side is the front?

With all our fibreglass filtration products there is a back and a front. It may not always be obvious, but it is important that the product is fitted correctly so that you are getting the most efficient and effective filtration. Our specialist PROPORA filter is no differant and it is the purple side that faces into the spray area.

The Propora is ‘progressively built’ which means that the fibres are closer together the deeper into the filter you go. So, the fibres are closer together at the back of the filter than they are at the front. This is so that the larger overspray particles are held on the front of the filter whilst the smaller particles are held towards the back. If the filter is fitted, back to front, then it will block very quickly.
