AIR COOLING KIT

TV 801 Bolted Flange with Navigator Controller

An air cooling kit (mod. 5214 NM) is available to
improve the TV 801 Bolted Flange cooling during
heavy operational conditions.
Single fan specifications:
3
− air flow: 187 m
− input voltage: 24 Vdc
− dimensions: 127 x 127 x 38 mm (5 x 5 x 1.5 in.)
− power: 4.6 W
To supply the fan it is necessary to connect the fan
supply to the P4 connector of the controller with the
special shielded cable included into the kit to reduce
noises and to accomplish to EMC norms.

CONNECTION OF THE FORE-VACUUM PUMP

A flange KF 40 NW is available to connect the
Turbo V 801 pump to the fore-vacuum pump. A
hose or vacuum approved pipe can be used. If a
rigid pipe is used, any vibration generated by the
mechanical pump must be eliminated through the
use of bellows.
The Turbo V801 pump is characterized by its high
compression ratio also for oil vapors. When using
a mechanical oil-sealed pump, it is advisable to
install a suitable trap between the turbopump and
the fore-vacuum pump in order to prevent oil
backstreaming.
