Aermec is the manufacturer of an aerosol propellant-filling machine. The aerosol propellant-filling machine is designed considering the need of a small perfume manufacturer. Salient features of the aerosol propellant-filling machine from aermec: the machine is compact and requires very little space for installation. It can fill gas in containers/bottles of size 200 mm [h] x 100 mm [dia]. Applications of the aerosol propellant-filling machine: the machine can be used to fill various items like perfumes, insecticides, mosquito repellents, lighter gases, oils, contact cleaners, pharmaceuticals and many other similar items, which need to be sprayed for maximum effectiveness. Process of feeling of the aerosol propellant-filling machine: the process of filling is very simple and can be easily mastered. The sealed container/bottle filled with liquid is placed on the bottle table of the machine and the table is pressed up to locate the bottle valve into the filling head nozzle. Then the ball valve provided above the head is opened to fill the liquid propellant into the container/bottle. The required quantity of the liquid is determined by the level of the liquid in the gauge glass and the scale provided under the acrylic front box. Once the desired quantity has been transferred into the bottle, the valve is closed and the container/bottle is removed from the machine. The container/bottle is now ready to spray. If pressure inside the propellant is not sufficient enough to fill the container/bottle, external pressure in the form of pure air or nitrogen must be applied through a booster inlet valve provided on the top of the machine. The machine is fitted with a silica gel filter/dehydrator to assure dust and moisture free supply of propellant.
