  • Device and method for cleaning particulate material
    Patent number: 5562779
    Abstract: A device for renovating synthetic grass playing surfaces which optionally include a layer of particulate material. The device comprises a plenum chamber (10) which directs a fast moving jet of air against the particulate so as to dislodge it and direct the particulate into a manifold (11) which partially surrounds the plenum chamber. The manifold is designed to separate out the fine particles and direct them to a collection area, and to lay the coarse particulate back on the surface. Filtering and collection apparatus is also described.
