The oil-water filter is bigger and the filtering effect is better Directly inflate the diving cylinder without air filter Water-cooled submersible breathing high-peable diving cylinder, with activated carbon filter, pure output. 110V Electric Air Compressor Diving Pump 30MPA. Voltage: 110-130v, 60Hz Rated power:1.8kw Motor speed: 2800r / min Working noise: 70dB Air output: 130L / min Cooling mode: water cooling Compression level: secondary compression Lubrication method: splash type Motor material: all copper coil Cylinder head material: cast aluminum Shell material: Steel Pressure range: 0-40MPa Working pressure: 0-30mpa (4500psi) Maximum temperature: 80?

Note: Oil: add piston type air compressor oil (the machine has no oil, because it is not allowed to carry oil by air) Speed test: it takes 3 minutes for 0.5L oxygen cylinder to inflate 30MPa, 6 minutes for 1L oxygen cylinder to inflate 30MPa, and 40 minutes for 6.8L oxygen cylinder to inflate 30MPa. Operation method of electric air pump: 1. Check the amount of oil before each use, the oil should exceed the red dot, but not too much. The Lubricating oil that is exported to foreign countries is taken out and needs to be added by itself. Replace the breathing plug. Change the oil cover used for transportation to a strip-shaped breathing plug. Loosen the air bleed screws on both sides before starting the machineRemember, the machine needs to start under zero pressure. If the bleeder screw is not loosened, the machine will not start. After starting the machine, tighten the bleed screws on both sides to press normally After the end of the inflation, loosen the deflated screw and then deflate, then take the inflation joint. To install the water pump, you need to put the water pump into the water. The more cold water, the better. After the water pump is normally circulated, the electric air pump can be turned on Manually shut down after reaching the required pressure, the whole process needs attention, and it is forbidden to leave. The mechanical pressure gauge directly screws the pointer to the required pressure. When the pressure rises to the set pressure after starting, it will automatically stop. Press the”SET”button to set the required pressure. PressON to start the machine. When the pressure rises to the set pressure, stop automatically. 1 x set of 30MPa high pressure air pump 1 x water pump 2 x water pipes 1 x filter 1 x spring hose 2 x pressure relief screws 1 x tank breather plug 1 x shock pad 1 x This manual.
