The use of sweepers places high demands on technical hoses. Heavily soiled media such as broken glass, metal parts, branches and leaves are transported through the hose at high speed. The hose wall is claimed immensely. For special operations such as these, the NORRES Group has developed special hoses that prove themselves in operation.

Special hoses for cleaning and sweeping machines

Long service life and a significantly reduced replacement of heavily used suction and blower hoses is a requirement for the NORRES Group in the area of hoses for municipal vehicles. Two hose types have been developed especially for this branch application, which can withstand the demands there: AIRDUC^® PUR 355 SWEEPER and AIRDUC^® PUR 355 SWEEPER REINFORCED. Both types of hose are abrasion resistant, microbe resistant and have a good low temperature flexibility. Despite its heavy and reinforced design, the AIRDUC^® PUR 355 SWEEPER is highly flexible and compressible. The protected, flow-optimizing exterior folds ensures high delivery capacity and low abrasion during use. Thus, a longer service life is achieved, resulting in an important product advantage. In addition, the AIRDUC^® PUR 355 SWEEPER has a good resistance to oil, gasoline and chemicals, is certified according to DIN 26057 Type 3 and conforms to RoHS guideline. The AIRDUC^® PUR 355 SWEEPER REINFORCED is a heavy-duty and reinforced hose type. It has outstanding interior smoothness and a good resistance to oil, gasoline and chemicals. Both types of hose can be used in a temperature range from -40 ° C to 90 ° C.
