Service life The technical performance data changes over the service life (wear and
contamination).
Sound level The sound emitted by the NTP can be dampened by covers (on request).
reduction This is only worthwhile if the impacted sheet metal is also insulated (e.g.
by heat insulation material).
8
have no impact plate, the piston swings against an air cush-
ion.
have an impact plate made of steel in the base plate (hard-
hitting with high noise level).
have an impact plate (elastomer disc) that is inserted in the
base plate.
