Pump Ranges
These operating instructions concern the following dry running rotary vane compressors: Models DTA 40 to DTA 140.
Versions (01) to (30) are with cooling exits from two sides (picture
on one side only (picture
). All models have nominal capacities of 40, 50, 60, 80, 100 and 140 m
cycles. The pressure limits (bar) are indicated on the data plate (N). The pumping curves showing capacity against
pressure, can be found in data sheet D 355.
Description
All models are complete with a threaded connection on the exhaust and a protection cap on the inlet. The carbon dust
which is the result of the carbon blades wearing is also separated by built-in filters. A high efficiency cooling fan is located
between the compressor housing and the motor. The compressor unit is encased in a rugged black sound enclosure. The
compressed air is cooled by an after cooler. All the compressor's pumps are driven by a direct flanged three phase,
standard TEFV motor via a pin and bush coupling.
Pressure can be adjusted to the required levels, however, they are limited to a maximum point.
Optional extras: As required, non-return valves (ZRK), suction filter (ZAF) and motor starter (ZMS)
Suitability
The units DTA are suitable for the use in the industrial field i.e. the protection equipments corresponds to
EN DIN 294 table 4, for people aged 14 and above.
The DTA units produce pressure up to the maximum limits, which are shown at the data plate (N). They may be operated
continuously.
The ambient and suction temperatures must be between 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 humidy of 30 to 90 %.
Dangerous mixtures (i.e. inflammable or explosive gases or vapours), extremely humid air, water vapour,
aggressive 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.
