This kit lets you carry out quantitative face fit testing on Portwest bayonet cartridge half masks and full face masks. It gives you confidence that each respirator fits the individual wearer.
The adapter connects to a Portacount particle counting device. Its sampling tube draws air from inside the mask, so testing is straightforward and the results are reliable.
