Operating & Feature

Condensed water is flowed into the trap through Inlet① (Refer to How to install) Condensed water reach a certain level(about 2/3), Float② is up by buoyancy.                            
At that time, the external Magnet③ sticked to Float② get down the internal Magnet④.                          
The external Magnet③ & internal Magnet④ are assembled with the same pole and they never sticked each other.               
When the internal Magnet④ get down, Control air is flowed to air cylinder⑤ and the cylinder get down and make ball valve(Φ15)⑥ open and then condensed water in trap is discharged.
The condensed water remains about 1/4, Float② get down and Magnet④ move up and shut control air supplying to air cylinder⑤.  Air cylinder⑤ discharge the balance air through the hole in cover and return by spring and ball valve is closed. It is done within 2~3sec. to discharge the condensed water by cylinder and shut again.
And there is no loss of compressed air because of remaining condensed water in bottom.

Installation 1

1. Connect inlet and outlet of condensed water pipe

2. Connect Control air line. [Use the clean dry air]

3. Connect the balance line as the picture.[The pipe of balance line should be over 15A]

4. Connecting should be separate for repairing.

5. Installation1) is the best connection.

6. Caution : Do not join the balance line to the water inlet.

 

 

 

 

Installation 2

1. Connect inlet and outlet of  condensed water pipe

2. Connect Control air line. [Use the clean dry air]

3. If the Balance line is not connected, open  slightly Speed control v/v.

4. There is a loss of air in the case of  Installation 2)

 

 

 

 

 

Installation3

1. If the condensed water outlet is higher than the trap,use the balance line hole with the condensed water inlet
2. Stop up the inet at the bottom with plug or valve.
3. Connect the control air line with clean dry  air.
4. Check the condensed water is flowed.
5. Discharge the early condensed water manually.

**  Notice
1. Shut the compressed air before installation.
2. Check the leakage of trap and pipe after installation.
3. Check the inflow to the trap.
4. Push test button and check how it works.
5. Connecting should be separate for repairing.
