Question 141General Subjects - 1st Asst/Chief
70% to passWhich of the filter/strainer units listed permits you to clean the element while leaving the system on the line?
ABypass
BCanister
CDuplex
DSimplex
AI Explanation
The correct answer is C) Duplex. A duplex filter/strainer unit allows you to clean the filter element while the system remains on the line. This is because a duplex unit has two separate filter housings, allowing you to isolate one housing for cleaning while the other continues to filter the system. The other options, such as a bypass or simplex unit, do not provide this capability, as they have a single filter housing that must be taken offline for cleaning.
