4.2 Description
The V-DTN range has a connecting thread on the pressure side and a silencer on the suction side. The as-
pirated air is cleaned by an inbuilt fi ne micro fi lter. The carbon dust caused by the scoring of the blades can
also be separated by an integral fi lter. The compressor is in a plastic sound cover. Inside the sound cover is
also a fan that cools the V-DTN.
The compressed air in sizes 16, 26 and 41 is cooled by a cooling segment with a greater motor output.
The pressure regulating valve (Fig. 2/D) is used to set the pressure to the required values with an upper limit.
4.3. Areas of application
These dry running rotary vane compressors, V-DTN 16 to V-DTN 41, are suitable for creating excess pres-
sure between 0 and the maximum limit (in bars) given on the data plate (Fig. 2/N). Constant operation is per-
missible.
The compressors have a nominal fl ow rate of 15, 25 and 40 m 3 /h at 50 Hz. The load limits (bars) on the pres-
sure side are given on the data plate (N). Data sheet D 381 shows the dependency of the fl ow rate on the
excess pressures.
These dry running machines are suitable for conveying air with a relative humidity of 30 - 90 %.
If the unit is switched on more frequently (at regular intervals of about 10 times an hour) or at
higher ambient temperatures and intake temperatures, the excess temperature limit of the motor
winding and the bearings may be exceeded.
Please contact the manufacturer should the unit be used under such conditions.
If it is installed in the open air the unit must be protected from environmental infl uences, (e.g. by a
protective roof).
