Page 5: General Information
These operating instructions and the fan name plate describe how to use the EX fans safely. ♦ Read the operating instructions completely and carefully. ♦ If used in potentially explosive atmospheres, examine the name plate. Only use type PRF-EX fans. Warning Protective clothing must be worn in potentially explosive atmospheres to reduce the risks to employee health. -
Page 6: Important Safety Information
| Important safety information Warning Regarding the choice of material, the EX fans fulfil the requirements of Standard DIN 14986 (Construction of fans for use in potentially explosive atmospheres) as a result of specific protection measures in areas of potential contact between rotating and stationary components (rotor/intake nozzle). A safety clearance to the intake nozzle is guaranteed for the rotating part. -
