STEP 2 - Remove Filter Bowl
• Different styles of air filters are available. The following instructions are
given for the most typical filter used, one with 1/4” pipe thread.
• Remove the bowl of the air filter by sliding the button downward and
twisting the bowl about 1/8 of a turn. The bowl should slide downward
from the upper portion of the filter revealing the filter element. Unscrew
the element as you would unscrew a light bulb. Hand tighten the element
after replacing it.
Make sure to replace the correct filter element.
- Blue or black filter bowl:
QED Filter element Part No. 205071
- Silver filter bowl:
QED Filter element Part No. 205800
STEP 3 - Bowl Drain
Optional Float Drain
• Wash out any deposits and oil buildup from the filter bowl with warm
water and soap. To make sure the float drain is operating freely, shake it;
the drain should rattle. Test the float drain by filling the bowl with water,
assembling the bowl to the filter and reconnecting it to the air supply.
The water should drain from the bowl. When under pressure, the drain
should not leak.
Standard Manual Drain
• With water in the bowl, open the drain and ensure the liquid drains easily.
When under pressure and closed, the drain should not leak.
