What to do if my WALKER FILTRATION PROSFD PD0046 has excessive or loud purge, or purge on only one tower?
- GGeorge MartinAug 17, 2025
If your WALKER FILTRATION dryer has excessive or loud purge, or purge on only one tower, it could be due to several reasons: * Jammed main control shuttle valve: Clean or replace the shuttles. * Jammed purge exhaust shuttle: Clean or replace the exhaust shuttles. * Faulty solenoid valve: Clean or replace the solenoid valve. * Not utilizing Energy Management feature: Refer to Energy Management instructions (Section 7). * Blocked and/or damaged silencer: Replace the silencer and check desiccant cartridges. * Damaged purge valve(s): Replace the purge valve bodies. * Incorrect purge orifice size: Double check and select the correct size.
