2 Drive or Industry-Specific Package
Each end user is grateful to know that high demands are made on hygiene in all “sensi-
tive production areas.” That statement applies to employees as well as all machines and
systems involved. Thus the food and beverage industry, as well as the chemical and phar-
maceutical industry make sure that no contaminated food, cosmetics or pharmaceuticals
reach the market. Oftentimes this even requires an absolutely sterile production environment.
The drive solutions used in such produc-tion areas have often seriously impaired the necessary cleaning processes of the production system. Standard motors often come equipped with cooling fins and fans in which dirt can accumulate and germs and bacteria may be distributed via air turbulences. It may also be impossible to remove the dirt completely due to poor accessibility of the drive components within
the system. Another problem occurs if the drive components are not resistant to the aggressive cleansing agents and disinfectants: The surfaces may be damaged (such as paint damages) and it may not be possible to maintain the hygienic guidelines.

Ambient conditions/sample applications
Suitable for machines and systems in buildings and rooms indoors with neutral atmospheres. Similar to corrosion category*: C1 (negligible) Sample applications – Machines and systems in the automobile industry – Conveyor systems in logistics areas – Conveyor belts at airports
Suitable for environments with condensation, and atmospheres with low humidity or contamination level, such as outdoors applications under roof or with protection. Similar to corrosion category*: C2 (low) Sample applications – Systems in saw mills – Hall gates – Agitators and mixers
Suitable for environments with high humidity or mean atmospheric contami-nation, such as outdoors applications subject to direct weathering. Similar to corrosion category*: C3 (moderate) Sample applications – Applications in amusement parks – Funiculars and chair-lifts – Applications in gravel plants – Systems in nuclear power plants
Suitable for environments with high humidity and occasionally severe atmospheric and chemical contamination. Occasionally acidic or caustic wet cleaning. Also for applications in coastal areas with moderate salt load. Similar to corrosion category*: C4 (high) Sample applications – Sewage treatment plants – Port cranes – Mining applications
Suitable for environments with permanent humidity and severe atmospheric or chemical contamination. Regular acidic or caustic wet cleaning also with chemical cleaning agents. Similar to corrosion category*: C5-I (very high) Sample applications – Drives in malting plants – Wet areas in the beverage industry – Conveyor belts in the food industry

DAS Series Motors
The DAS series motors are not equipped with fans, which prevents a distribution of germs
by air circulations. They are available in three motor sizes of types DAS80, DAS90 and
DAS100 that can be mounted directly to helical, parallel shaft helical, helical-bevel,
helical-worm or SPIROPLAN® gear units. The smooth surface of the DAS series motors
makes for easy cleaning. This design prevents the accumulation of dirt and almost
completely prevents the formation of germs or bacteria.
Advantages of the DAS series Gearmotors from SEW-EURODRIVE also create the perfect conditions in your production system for the production and packaging of food and beverages as well as pharmaceutical products.
– Smooth surfaces: no dirt build-up– No fans, pure convection cooling and no air
turbulences – Good protection against humidity– Three motor sizes DAS80, DAS90 and
DAS100– Motor power from 0.25 -1.5 kW in S1
continuous duty
– High degree of protection as standard – Motor protection TF thermistor in thermal
class F, TH optional– Connection via integrated IS connector in high
degree of protection (reliable four-bolt con-nection, high flexibility through star or delta connection in connector) – resulting in low maintenance and service requirements
– Motor to be mounted directly on standard R, F, K, S and W gear units

Advantages of the ASEPTICplus drive packageThe ASEPTICplus drive package for the gearmotor (DAS series) offers a high degree of protection against corrosion as well as aggressive cleans-ing agents and disinfectants. In addition to the high-quality material used for bolts, oil seals and output shafts, the drives are completely protected by the OS4 surface treatment.
SEW-EURODRIVE had the resistance of the OS4 surface treatment tested and certified for those cleansing agents and disinfectants customary in the different branches of industry. Such a sur-face treatment meets the high requirements made on a hygienic environment. It also dramatically increases the service life of the operated drives and the availability of the entire system.
