Morning every body!

We are going too overhaul a SABROE 163 HR(Rotatune). The question that we have is following:
Is it possible that the SAB 163 HR unit have 2 pcs of oilseparationfilter(coaelsterfilter) or is it only 1 pcs.
The thing is that the unit is possible to open in both(flange) end of the oilseparator. But it is only one dishargepipe out from the oilseparator.
Is it two filter only because it is a rotatune??
The temperature is (Evap) 0 / (Cond) +35 celcius.
Oiltype Mobil SHC 226E.
