Description
All models are complete with an inlet threaded connection and a silencer on the exhaust. All the air handled is filtered
by a built-in micro-fine filter. A high efficiency cooling fan that pulls air in is situated between the pump housing and the
motor. On version (01) the fan is located in the fan housing (see pictures
exhausted out of the fan housing (W
the heated cooling air (F) can be directed either upwards or to the side depending on the position of the spiral
housing (W
). It is also possible to connect ducting to the spiral housing so that the cooling air (F) can be transported

away from the unit.
All the pumps are driven by a direct flanged three phase, standard TEFV motor via a pin and bush coupling.

suction filter (ZVF), motor starter (ZMS), softstarter (ZAD), unloading valve (ZAE), various vacuum gauges (ZVM) and
