Ventilation and Welding Hoses

Ventilation and welding hoses are used in low-pressure air suction and exhaust lines. Most hoses have PVC-coated fabric walls and are externally reinforced with a galvanized steel spiral against abrasion; flame-retardant and antistatic models are available. Compressible at ratios from 1:3 to 1:9, the hoses are also used for ventilating tents, vehicles, ships, tunnels and mines.
