+ PWTU 27/54 M82 &
PTU + PWTU 27/108 M82
Application:
The PTU 27/-series of filter separators are used for fine filtration and water separation
on hydraulic oils and turbine lube oils with a specific weight lower than that of water
and which does not form stable emulsions with water.
Function:
The filter pump sucks oil, e.g. from a system tank, and presses it through the filter
element. From the center of the element the oil flows down into the filter base where
water droplets, if any, adhere to the coalescer element, forming larger drops that will
settle in the bottom of the coalescer housing. From the top of the filter base the oil
will flow back to the tank.
On type PTU separated water can be drained manually from the filter base whereas type PWTU is equipped with an automatic water discharge system. The discharge function is monitored on the unit control box.
The pressure drop over the filter - and consequently the contaminant absorption of the filter element - can be monitored on the pressure gauge on the filter top. In addition, PWTU models are equipped with an electric pressure guard including automatic malfunction shut-down.
The filter is installed with a suction line connected to the most contaminated point in the system tank - preferably to the bottom drain, if existing.
