Mainly used in gas filtering, pressure regulating and pipe lubricating inside the air pressure line. Based on different functions, can be divided into filter, regulator, lubricator and products with multipurpose, ex: filter regulator.

➤ Filter

• The Air with moisture and impurities enters the filter from primary air hole.
• The air flows through the vortex ring creates a cyclone and throws the condensed water to the cup wall.
• The gas flows out of the OUT terminal after it filtered by the element.
• The steam in the air will condense into water and collected in the PU cup. Then the drain will be turned on when the water level rises to raise the float and will be off when the level drops.

➤ Mist Separator

• The air with mist enters the mist separator from primary air hole.
• The mist will fill the cup when the element filters most of the mist from the air.
• The filtered air will flow out of the OUT terminal.

➤ Vacuum Filter

• Negative pressure enters the body from the OUT terminal.
• Negative pressure enters the body and fills the lower cup space.
• The filtered compressed air flows out from the IN terminal.

➤ Filter Regulator

• After the air supply enters from the primary air hole, the air flows through the vortex ring will create a cyclone and throws the condensed water to the cup wall, and then drops into the PC cup.
• When the water level rises, it will raise the float and open the drain, and then the water will be out from the drain.
• Adjust the spring and press down the diaphragm, and the diaphragm will push the shaft to separate from the gate. Then the air enters the gap between the rod and the shaft and discharges from the air outlet to keep the spring down.
• Adjust the spring up to reset the diaphragm. When there is gap between the shaft and the diaphragm, the air will discharge through the diaphragm port to the body exhaust port, to achieve the purpose of fast exhaust and pressure decrease.

➤ Mist Filter Regulator

• The air with moisture and mist enters the filter from primary air hole.
• The air will flow to the pressure plug ring after the element filters most of the mist from air, and then the pressure plug ring will go up to shut down the gate.
• Turn the pressure adjusting knob to set the secondary pressure, drive the pressure regulating spring downward, then press the diaphragm and push the pressure plug ring downward to open the valve port so that the air can flow out to the OUT terminal from the valve port.
• When reducing the pressure by reversing the pressure regulating nut, it will drive the pressure regulating spring upward and open the diaphragm immediately. Then the air will discharge through the diaphragm port to the body exhaust port, to achieve the purpose of fast exhaust and pressure decrease.

➤ Regulator

• After the air supply enters the body from the air inlet, the pressure plug ring will shut the valve port to make sure the air supply can’t discharge from the outlet..
• Rotate the pressure regulating knob clockwise to make the pressure regulating spring push the diaphragm and drive the pressure plug ring to separate from the valve port. At this time, compressed air flows in from the gap between the pressure plug ring and the valve port, and then discharges from the air outlet. If keep turning the pressure regulating knob clockwise, the pressure of the spring will keep rising.
• Rotate the pressure regulating knob counterclockwise to lower the pressure regulating spring and reset the diaphragm. At this time, it will create a gap between the shaft and the diaphragm, and the air will discharge through the diaphragm port and to the body port, to achieve fast exhaust and pressure decrease.

➤ Precision Regulator

• Starts the operation, the air supply enters from the primary side and guided by the inside, and pressed into the air conduction area through the throttle valve, and then flows into the air cavity through the nozzle, slightly gas will discharge to the atmosphere.
• Rotate the pressure adjusting button clockwise, the spring will compress, force the overflow diaphragm and steel ball go downward, and the amount of the overflow nozzle gas will reduce, the pressure of the air conduction area will increase, force the main diaphragm go downward.
• After the main diaphragm is pressed down, the valve port will open, allowing the air supply to flow into the secondary side from the valve port. At the same time, the gas will be pressed into the balance diaphragm through the orifice; the pressure will rise and equal to the spring pressure.
• Rotate the pressure adjustment knob counterclockwise, the spring pressure will decrease, and the overflow from nozzle will increase, so that the pressure of the air conduction zone will decrease and force the main diaphragm to move upwards. At the same time, the exhaust valve will be opened to discharge the unnecessary gas.
• By adopting the overflow flow control method of the nozzle and the steel ball, the pressure deviation can be adjusted sharply to achieve precise pressure control.

➤ Vacuum Regulator- ERV200

• Turning the screw right to rotate, force the nut to push down the main spring, and then the main diaphragm will push the shaft, avoiding the atmosphere from into the body, and open the valve to let the vacuum suction into the body.
• When turning the knob to left, the elastic force of the main spring drops, forcing the overflow hole above the main diaphragm to separate from the shaft and guide the vacuum force out of the body, reducing the vacuum pressure when the vacuum force drops.
• When keep turning the knob left to the origin and rotate the screw, forces the nut goes up to the origin and reset the main spring and the main diaphragm, and force the shaft to close the valve.

➤ Vacuum Regulator- ERV300

• After the vacuum air supply enters the main body from the left air inlet, the air at the suction port can’t be sucked in because the main valve port is closed.
• Adjust the spring to press down the main diaphragm; the main diaphragm will drive the shaft to open the main valve port. At this time, the vacuum air supply enters the suction port from the gap between the shaft and the valve port; Keep adjusting the spring downwards to raise the vacuum pressure.
• Adjust the spring upwards, the main diaphragm will instantly returns to its position. At this time, it will create a gap between the shaft and the diaphragm. And the atmosphere reaches the air outlet through the main body suction hole, diaphragm port and shaft central hole to break the vacuum and quickly reduce the vacuum pressure.
• Adjust the spring upwards to separate the main diaphragm and the shaft to create a larger gap. The atmosphere will pass through the diaphragm port, the shaft central hole, and then to the body suction hole to break the vacuum, achieve the purpose of quickly reducing the vacuum pressure and turn it back to square one.

➤ Lubricator

• Air enters the main body from the primary side, and most of the mainstream air pushes away the slider and discharges from the secondary side.
• The rerouted air enters from port A and blocked by pushing the check valve.
• A very small part of the rerouted air enters the oil cup through the tiny slot hole.
• When the oil surface is pressed, the lubricating oil will be pushed up along the oil suction pipe, and push the steel ball to flow to the oil volume adjustment button to control the oil volume.
• Rotate the oil volume adjustment knob to control the amount of oil into the oil window.
• The oil in the dropper flows into port C and atomized by the high-speed airflow, and then discharges from the secondary side.

➤ Shut-off Valve

• Starts the operation, the air supply enters through the primary side, without the upper knob turning clockwise to prevent the gas from flowing into the secondary side.
• Starts the operation, the air supply enters through the primary side, and rotates clockwise through the upper knob to drive the sliding shaft downward.
• Starts the operation, the air supply enters through the primary side, and the upper knob rotates clockwise to drive the sliding shaft downward, then the gas flows into the secondary side.
• Back to original, the air supply enters through the primary side, and the upper knob rotates counterclockwise to drive the sliding shaft upward to prevent the gas from flowing into the secondary side.
• Back to original, the air supply enters through the primary side, and the upper knob rotates counterclockwise to drive the sliding shaft upward to prevent the gas from flowing into the secondary side. At this time, the remaining pressure oil will be discharged from the underneath silencer.

➤ Start-up Valve

• The air supply enters through the primary side. After energizing the solenoid valve, the gas flows to the solenoid valve through the guide hole, and then the solenoid valve will supply gas to the upper layer of the P piston.
• The P piston operates downward to close the exhaust port. The gas flows in from the primary side, and the gas flows into the upper layer of the A piston through the guide hole. At this time, the internal and external pressures are balanced.
• Rotate the lower knob counterclockwise to drive the needle valve down, and the gas flows into the secondary side.
• After the solenoid valve disconnected, the air supply closed, the P piston returns to open the exhaust port and close the primary and secondary channels at the same time to prevent sonic boom. Then the internal air discharges from the exhaust port.
