Description

1 Characteristic
1) Based on the high elasticity, high air-tightness and medium resistance of rubber and the flexibility and heat resistance of fiberglass fabrics
2) The product is designed with short metal pipes and flanges connection with fan and air duct on two ends so as to compensate for the thermal expansion needed by operating air duct and for the displacements.
3) For the main materials are rubber or finer fabrics and the fibers have features of temperature preservation and thermal insulation, no reserve thrust and light weight, it needs no pipe bearing and saves lots of materials and labors
