Features: 1. The products adopts electric magnetic motor, and the air is produced by piston in the way of straight-line and reciprocal motion, and it has more reasonable structure 2. Non-oil lubrication and pure compressed air 3. Adopt SF1 new type wearing-resistant material for the piston and cylinder , which is of low power consuption, large air output and high air pressure. 4. The case is made of high-quality ZL102 aluminum alloy with streamline design.and heat-dissipation is more effective. 5. Phosphorize disposition, regualar coloring and adhesive strength. Application It's used for planting aquarium plant, aerating for seafood in hotels, restaurants, seafood booths, and feeding pool etc, it's also used for air supply to spare parts of food machine, medical instrument, belching lamp and new type paint, making and designing advertising LPG and LNG etc. Note : Placethe machine above water level ot protect water from flowing backwards, or it should be fit wit a non-return valve.
