Cassette sweeper brush

for airport runwayrubberwith metallic thread

The profile on SAJA® tufted brush cassette is filled with bundles of galvanized steel wire. Sturdy construction ensures peak performance in the maintenance of runways, taxiways and other paved areas – no matter if there is ice, snow, rubber, or FOD on the surface. Tufted steel wire cassette is available in various profiles and lengths to fit the brush core of the sweeper. The length of SAJA® brush cassettes is optimized for the brush core of each runway sweeper and sweeper-blower manufacturer. With just the right fit, you achieve the full sweeping width for your machine. TECHNICAL SPECIFICATIONS We use steel wires only from the most recognized suppliers, to ensure the highest standards and steady quality. Steel wire is galvanized to withstand chemicals used for the runways and taxiways. Single wires have 3-dimension corrugation to prevent the wires to break in rpm’s up to 1250. Material used in the bushings is ”thermoplastic elastomer”, in order to ensure the highest durability in most demanding weather conditions and physical stress. The bushing retains its flexibility even in very low temperatures. The material has been tested in Finland’s rough winter conditions for example in Ivalo, Enontekiö and Kittilä Airports, where the temperature can easily reach -35 degrees Celcius. The core of the cassette is made of Polyethylene for many reasons. As the bushings, also the profile endures low temperatures down to -35 degrees, which is mandatory in Scandinavian winter conditions. Polyethylene (HDPE) provides high stiffness in combination with outstanding impact strength even at very low temperatures.
