Technical Notes: 1. On Models PD0046 - PD0360 Walker Filtration recommends that an XA (0.01 micron) pre-filter, is installed upstream of the dryer and an RXA (0.01 micron) dust filter is installed downstream of the dryer. 2. Walker Filtration Water Separator supplied as standard. Walker Filtration Water Separator must be installed. If bulk water enters the adsorption dryer, it can cause heat expansion to the desiccant, substantial rise in the dryer differential pressure, lead to poor outlet dew point, and cause potential dryer failure. 3. All dryer applications and sizing should be confirmed by Walker Filtration. Please contact nearest sales team for information on recommended sizing and air quality for your application need. 4. Full Dew Point Management Control (DMC) option includes digital dew point display and dew point sensor (hygrometer), providing advanced dryer control based on outlet dew point. 5. Floor fixing dimensions are given in the above illustrations. 6. For PRODRY sizing and further information on service kits and accessories. 7. High Performance Cartridges are required for applications where -70° and -74°C dew points are requi
