Regulation of The frequency of the NTP should be set or regulated with the pressure
frequency regulator of the maintenance unit. Use a 3/2-way valve.
The frequency is reduced by lowering the air pressure before the NTP.
The centrifugal force is hereby also reduced. At the same time the ampli-
tude remains almost constant.
Regulation of If required, install a throttle valve in the exhaust air line in order to regulate
amplitude the amplitude of the NTP by throttling the exhaust air.
Notice: Reduced cross-sections already throttle (observe the nominal di-
ameter).
By throttling the exhaust air, the centrifugal force is reduced. The frequen-
cy hereby remains almost constant.
Recommendation: Reduce the amplitude only up to approx. 50 %. This
can cause start-up problems if below.
Setting mist Set the mist lubricator to the smallest safely adjustable number of drops
lubricator while the NTP is running. The NTP is ready for operation only after ad-
justment and correct functioning of the mist lubricator.
