- Page 1 Installation and operating manual AOK 50B / AOK 50SS Please read the following instructions carefully before installing the product. Trouble free and safe operating of the product can only be guaranteed if recommendations and conditions stated in this manual are respected.
- Page 3 Description The AOK 50 was designed to eliminate condensate, and other non-corrosive liquids from high- pressure compressed air systems. Condensate forms when compressed air is cooled. It forms in the pipeline and collects in the lowest parts of the compressed air system (pressure vessels or pipeline). To remove the condensate from the system, it is necessary to install a drain valve.

Page 9: Safety Instructions
Safety instructions Installation and maintenance work may only be carried out when the device is not under pressure. To depressurize the device, close the ball valve and rotate the test button on device until the pressure in it drops. Installation and maintenance work may only be carried out by trained and ... -
Page 10: Operation
Operation AOK 50 works with compressed air, which is in the system from which we wish to drain the condensate. The AOK 50 minimum operating pressure is 8 bar (116 psi). When there is no pressure in the system the valve is normally open. The valve opens automatically if the pressure drops to below 1 bar (14 psi). - Page 11 On the front side of the AOK 50 is a TEST button, which if rotated in a clockwise direction activates the servo valve, which opens the outlet and drains the condensate. This can be done at any time. The button can also be used as a release of pressure from the system. But for longer release times of compressed air from the system, we recommend disconnecting all devices from the OUTLET connection, such as traps, oil separators, piping, ...
- Page 12 Installation guidelines Warning Before installing the device, check that the system is not under pressure. Wear necessary personal protective equipment and keep folow the safety rules when working with pressure equipment. Before connecting the drain, blow compressed air through the piping in order to thoroughly ...
- Page 13 Do not connect several condensed water sources to one drain device because air would bypass filtering (left). Instead, each drain where water condensate collects must have its own condensate drain device (right). Drainage piping must be built without traps that would trap air in the AOK 50 and prevent ...

Page 14: Maintenance
Maintenance Warning Before maintenance depressurize the device and keep to the safety rules when working with pressure equipment. Weekly: Rotate the "Test" button and manually drain the accumulated condensate until air begins to blow from the drain. If a significant amount of water (more than 0.5 liters) exits the valve then the drain must be thoroughly cleaned. -
Page 15: Troubleshooting
Troubleshooting Leaks from hole at bottom of artist but AOK 50 is working normally. In case condensate and gas is leaking out check the pipe 44 (20) and the seals the tube (12). You can also check the elbow (18) where the tube (20) is fixed and the surface of the seal. Leaking gas at the OUTLET connector but the AOK 50 is working normally. - Page 16 OMEGA AIR d.o.o.
