Welcome to HYDAC Australia. In this video, we will show you how to operate an Offline Filtration Trolley, HYDAC OFTM.

The OFTM is an air operated mobile oil service unit used to filter oil when filling systems, transferring hydraulic and lubricating fluids and to provide offline fluid filtration.

The unit has a unique foot operated lever that tilts the wheel into the best position, reducing the load on the operator. It also allows the unit to be locked safely into position before starting the operation.

Make sure you have clean dry air available. We recommend between 6 to 12 bar.

Select the oil card according to the fluid that is going to be used. As the trolley is capable of handling different fluids, including HDA Glycol, the cards inform other operators of the fluid that is currently being used.

To start the operation, remove the suction hose, which is the hose that has a larger diameter, from the trolley and places it in the tank or drum.

Do the same with the return line hose, which is the hose that has a smaller diameter.

Ensure that the air isolation valve is closed and connected to the air supply.

Turn the air isolation valve on.

The operating speed of the OFTM unit should be selected to avoid cavitation of the pump, in this case, we have a low viscosity fluid, but when using high viscosity fluid the pump speed must be reduced.

Select the mode you would like to operate the trolley in, transfer or filter. The ‘transfer’ mode will only transfer the fluid from one tank to another without using your filter element. On the ‘filter’ mode, the oil passes from the pump through both filters in cascade. You can change the mode without turning off the pump.

And it also has test points to allow the connection of a particle counter with 1 point pre-filter and 1 point after filter.

The filter element is easy to change and doesn’t require special tools. Use your hand to unscrew the housing and replace the element.

The pressure indicators are visible from both sides.

The OFTM is convenient for offline filtration, easy to operate and aimed to reduce the life cycle cost of your system.
