CCT Pneumatic Principles & Air Flow Mechanics 2

Question 1

What does CFM stand for in Casper pneumatic tube system blower specifications?

Accepted Answer

Cubic Feet per Minute

Answer

CFM (Cubic Feet per Minute) is the standard unit for volumetric airflow rate and is a key specification when selecting or replacing blowers in pneumatic tube systems.

Question 2

How does installation at high altitude affect Casper pneumatic tube system performance?

Accepted Answer

Reduced air density at altitude requires increased blower capacity to maintain performance

Answer

At higher altitudes, lower air density reduces the pressure differential a given blower can generate, requiring larger or faster blowers to compensate.

Question 3

What is the function of an inlet air filter in a Casper pneumatic tube system?

Accepted Answer

To remove dust, debris, and particles from the airstream before they reach the blower

Answer

Inlet filters protect blowers and system components from contamination by trapping particulates in the airstream before they can cause mechanical wear or blockages.

Question 4

In pneumatic tube system airflow analysis, what does 'static pressure' represent?

Accepted Answer

The resistance force that the blower must overcome to push air through the system

Answer

Static pressure is the resistance component of air pressure — it acts perpendicular to airflow and represents the system resistance the blower must overcome.

Question 5

In a bidirectional Casper pneumatic tube system, how is carrier direction reversed?

Accepted Answer

Reversing valves redirect blower airflow so it draws from the opposite end of the tube

Answer

Reversing valves switch which end of the tube network the blower draws from, flipping the pressure gradient and driving carriers in the opposite direction.
