The Gamrat Went System includes polyvinyl chloride hoses with helical reinforcement used as conduits and exhaust ducts. The basic version of the system is used for removing dust and fumes in vacuuming devices.
The Gamrat Went hoses are available in two versions: standard and explosion-proof. For both versions, the wall consists of grey softened PVC material supported by a helix of hard PVC material. The inner surface is smooth.
The Gamrat Went System is suitable for operation at temperatures from -10°C to +55°C.
Depending on a type, hoses withstand without a damage different vacuum pressure. When pressure tested up to 10 minutes at 23°C, the Type 2 (light) hoses do not fail due to collapse or fracture at pressures up to 50 kPa (absolute pressure of 35 kPa) and the Type 3 (heavy) hoses do not fail due to collapse or fracture at pressures up to 60 kPa (absolute pressure of 40 kPa).
