Model MDG1.7 nitrogen filler (referred to as filler hereinafter) can be used for filling nitrogen to cylinders to be pressurized by nitrogen in the manufacturers of fire fighting equipment. For instance, after the cylinder is filled with dry powder, inactive gas-nitrogen has to be filled for pressurization. When the dry powder cylinder is used for putting out a fire, the dry powder will be sprayed quickly to the flame together with the pressurized nitrogen to extinguish the fire promptly.
The filler is made up of the constant pressure control filing system and features safety and reliability, simple operation, high efficiency and great precision of filling pressure. Therefore it is an ideal filling device for manufacturers and maintenance works of fire fighting equipment at present.
