Question

Technician A says that a crossdraft spraybooth is the most efficient type of dust control spraybooth used.

Technician B says that a downdraft spraybooth may recirculate heated air.
Who is right?
A) Neither A nor B
B) A only
C) B only
D) Both A and B

Answer 1

Technician B is correct. A downdraft spraybooth may recirculate heated air for energy efficiency.

Step-by-step explanation:

Technician B is right. A crossdraft spraybooth directs air horizontally across the work area, while a downdraft spraybooth pulls air down and out through the floor grates. Downdraft spraybooths are considered more efficient because they create a controlled airflow pattern that helps to minimize contamination. However, in a downdraft spraybooth, heated air can be recirculated to maintain a consistent temperature, increasing energy efficiency.
