Model: OL2/OL21; OL2S/OL21S

The lubricator is intended for mist-lubrication of controls and peripheral equipment in pneumatic lines, as required, by automatically sending oil in mist from the pneumatic line. This extends the service life of the components in the pneumatic line and improves their efficiency.

Operation

❶ Check valve 

Part of the air entering the IN port passes through the check valve and pressurizes the oil in the bowl. When the oil is added（filter plug removed）with the oil under pressure, the ball of the check valve is forced against the seat, and the air is prevented from entering the bowl. In practice, however, the check valve is not closed completely, and a very small amount of air continues to enter the bowl. This does not hinder lubrication.

❷ Siphon tube 

A pressure differential in the sight glass causes oil to pass through the siphon tube to the adjusting screw section.

❸ Oil spray section 

Here, oil droplets turn into minute mist particles and are diffused in the air.

❹ Sight glass 

As pneumatic pressure enters the IN port, a pressure differential results in the sight glass. The oil sent there through the siphon tube falls in the form of droplets through the drip tube.

❺ Oil quantity adjustment 

The rubber plate automatically adjusts the oil quantity if the airflow varies.

❻ Adjusting screw 

Turning the adjusting screw counterclockwise increases the number of oil droplets while turning it clockwise reduces the quantity.

❼ Side glass 

This is used to check the oil level in the bowl.

Operating Instructions

1. Installation 

● The install of the lubricator bowl must be downwards vertically.

● Install the lubricator as near to the actuator as possible. Avoid placing a rising pipeline between the lubricator and actuator.

● Provide room so that the bowl can be removed for maintenance and checking.

2. Adjusting the quantity of oil droplets 

● To increase the quantity, turn the adjusting screw counter-clockwise.
● To reduce the quantity, turn the adjusting screw clockwise.

3. Type of lubricator oil 

● Use JISK2213 turbine oil with additive, or the equivalent of ISO VG32 or 46. （Do not use spindle oil.）

4. Lubrication 

● Oil can be added even during operation. To feed oil, remove the filler plug and pour oil through the filler port.
● It is recommended that oil be supplied at regular intervals on the basis of the expected amount of oil consumption, calculated from the frequency of line operations.
