The difference between ducting and a hose essentially comes down to size,
wall thickness and the media you push through them.
Hoses are designed to be generally smaller in diameter than ducts.
Ducting and ventilation hoses are very lightweight and flexible.
They are designed to extract and convey gases and fumes of different substances,
dust, sawdust, wood shavings, wood chips,
loose bulk materials and granules, also highly abrasive.
Duct hoses are hoses that are installed in buildings, facilities, vehicles,
etc., and used for sending and exhausting, collected dust, discharging powder,
etc. Duct hoses have various characteristics such
as flame retardance, cold resistance, oil resistance, etc.

Hoses are designed to be generally smaller in diameter than ducts.
Applications mostly use nylon, polyurethane, polyethylene, PVC,
or synthetic or natural rubbers, based on the environment and pressure
rating needed. In recent years, hoses can also be
manufactured from special grades of polyethylene (LDPE and especially LLDPE).
