Extension Ventilation Hose

Extension ventilation hose1.StructureIts structure is as follows:Extension hose (Type G): the hose is made of inner layer, fiber heat insulation, cover layer, metal spire, and anti-wear strip. It is applicable under bent state condition.2.Main performancesWorking pressure (feeding pressure): Temperature: -30oC to +80oC Feeding medium: 5oC to +60oC cold & hot air Heat insulation: when cold or hot air through the hose under normal condition, the average temperature change is no more than 0.1/m of the hose. Retractility (type G):the hose can be compressed to 1/4 of its longest natural stretch length. Pneumatic property: leakage of feeding medium is no more than 1% of 10-meter hose. Liquidity resistance: the loss of feeding medium is no more than 0.1kPa/m of the hose. 3.Material propertyInner layer: it is made by coating nylon with PVC or CR, and have good performances in sealing, age-resistance, heat resistance and cold resistance, etc..Heat insulation: it is made of terylene fiber with thermal reflective film, has advantages of heat preservation, heat & cold resistance, anti-friction, no agglomerate, no powder, etc..Cover layer it is made by coating nylon with PVC or CR, has advantages of anti-sunlight or ozone aging, heat resistance, rain or water proof.Anti-wear rubber strip It is made of natural SBR which has good performance of anti-wear (which is the material for tire).4.ApplicationMobile air conditioning device (air conditioned car for aircraft)Stationary air conditioning device in airport (air conditioner for Gallery Bridge)It can transport cold and hot air in other occasions.
