Suitability
The units DTB are suitable for use in the industrial field
i.e. the protection equipment corresponds to EN DIN
294 table 4, for people aged 14 and above.
The DTB compressors produce compressed air up to the maxi-
mum limits as shown on the data plate (N). They can be operated
continuously.
The ambient and suction temperatures must be be-
tween 5 and 40° C. For temperatures outside this range
please contact your supplier.
These dry running compressors are suitable for use with air of
a relative humidity of 30 to 90 %.
Dangerous mixtures (i.e. inflammable or explosive gases
or vapours), extremely humid air, water vapour, ag-
gressive gases or traces of oil and grease must not be
handled.
The standard versions may not be used in hazardous areas.
Special versions with Ex-proof motors can be supplied.
For all applications where an unplanned shut down of
the compressor could possibly cause harm to persons
or installations, then the corresponding safety backup system must be installed.
Handling and Setting up
Compressors that have reached operating temperature may have a surface temperature at position (Q) of more than 70° C.
WARNING! Do Not Touch. (see pictures
The filter housing (S), exhaust box (T), housing cover (b) and greasing points (L) must all be easily accessible. For maintenance purposes we
recommend a space of 0.4 m in front of the filter housing and housing cover. The cooling air entries (E) and the cooling air exits (F) must have a
minimum distance of 20 cm from any obstruction. The discharged cooling air must not be re-circulated. If the cooling air exits from the spiral
housing (W
) via ducting, then care should be taken so that the passage of air is not obscured (see pictures

The DTB compressors can only be operated reliably if they are installed horizontally.
For installations that are higher than 1000 m above sea level there will be a loss in capacity. For further advice please contact your
supplier.
When installed on a solid base, these compressors do not require fixing down. If the compressors are installed on a base plate we would recommend
fitting anti-vibration mounts. This range of compressors is almost vibration free in operation.
Installation (pictures
to
These compressors may not be operated without the standard pressure regulating and limiting valves fitted so that the maximum
pressure is not exceeded (see data plate).
The safety valve is a wearing item and must be changed after 10,000 h or at the latest 2 year operation.
For operating and installation follow any relevant national standards that are in operation.
1. Pressure connection at (B).
Long and/or small bore pipework should be avoided as this tends to reduce the capacity of the compressor.
2. The electrical data can be found on the data plate (N) or the motor data plate. The motors correspond to DIN/VDE 0530 and have IP 54
protection and insulation class B or F. The connection diagram can be found in the terminal box on the motor (unless a special plug connection
is fitted). Check the electrical data of the motor for compatibility with your available supply (voltage, frequency, permissible current etc.).
3. Connect the motor via a motor starter. It is advisable to use thermal overload motor starters to protect the motor and wiring. All cabling used
on starters should be secured with good quality cable clamps.
We recommend that motor starters should be used that are fitted with a time delayed trip resulting from running beyond the amperage setting.
When the unit is started cold, over-amperage may occur for a short time.
The electrical installation may only be made by a qualified electrician under the observance of EN 60204. The main switch must be
provided by the operator.
Initial Operation (pictures
The desiccant bags in the filter housing (S) must be removed before initial start-up.
Maximum number of starts per hour: 6 (DTB 180 / 250), 4 (DTA 340 / 500)
1. Initially switch the compressor on and off for a few seconds to check the direction of rotation against the direction arrow (O).
Note: On this initial start the pressure pipework should not be connected. If the compressor runs backwards with the pipework
connected a pressure could build up within the housing which could result in damaged rotor blades.
2. Connect the pressure pipe at (B).
For pipe work longer than 3 m we recommend using non-return-valves (ZRK), to avoid reverse rotation when the units are switched
off.
3. The required pressure ranges can be adjusted by turning the
pressure regulating valve (D) according to the symbols on the
top of the regulating valve.
Potential risks for operating personnel
Noise Emission: The worst noise levels considering direction
and intensity (sound power), measured according to DIN
45635 part 3 (as per 3. GSGV), are shown in the table at the
back. When working permanently in the vicinity of an operat-
ing compressor we recommend wearing ear protection to
avoid any damage to hearing.
