The IFEX trolleys with their capacities of 35 to 50 litres allow the user to achieve more than a first attack. He can use the standard breathing apparatus and still be mobile and flexible; the water capacity for up to 50 impulse shots provide him with a fire stopping power to keep even large structural fires under control. The trolley consists of a water/agent cylinder, a 6 litre air cylinder and the pressure regulator with two outlets. The unit is assembled on a wheel base with brackets for the impulse gun, the air cylinder and a 15 meter coaxial hose.
