Desiccant cartridge for dMED 25 & dMED 35 dryer 

 

1.  Remove prefiltration and hoses. 

2.  Unscrew four bolts ¾ turn on the opposite tower to aid 

desiccant changeout process. 

3.  Unscrew the four pressure housing retaining bolts and 

slide out the pressure housing. 

4.  Remove banjo fixing bolt using hex key. 

5.  Extract end cap and banjo assembly from pressure housing. 

6.  Using banjo fixing bolt, retract the cartridge from pressure 

housing. 

7.  Replace with new cartridge supplied as part of the cartridge 

service kit. 

8.  Ensure O-ring seals are in place when installing cartridge and 

assembly in pressure housing. 

9.  Follow above steps in reverse to finish installing new 

cartridge into the dryer. 

10. Repeat steps 1 – 10 for the second pressure housing. 

11. Ensure the dryer is leak-free before operating pressure is applied to the dryer. 

12. Follow start up procedure as stated in the operations section of this manual. 

 

 

Desiccant cartridge for dMED 45 - dMED 300 dryer 

 

Maintenance information leaflet is provided with each desiccant cartridge replacement kit 

showing how to carry out the change out. 

 
Warning 

 

 

 

To ensure that the unit always produces pharmacopoeia compliant air, only dedicated and 

genuine spare parts must be used. 

 

The installation and maintenance must be done by trained and certified personnel. 

 

 

 

Pharmacopoeia compliance

 

 

 

 

When replacing desiccant, make sure that the desiccant is disposed of according to the 

local regulations. 

Consult the parts list for part numbers. 

 

 

 

 

 

After carrying out any maintenance or repair work, Pharmacopoeia testing must be done 

by a local testing company to assure reliable and correct operation of the unit. 

 

 

 

Ensure shutdown and start up procedures are followed prior to carrying out any 

maintenance work on the dryer
