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 PROFIBRE rolls are coloured green and white and it is the green side that faces into the spray booth therefore it is this face that the overspray hits. If you are using our specialist PROPORA filter, then it is the purple side that faces into the spray area.

Both these filters are ‘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.
