Which is the most common type of eductor carried on our apparatus?

• A. Venturi eductor
• B. Inline foam eductor
• C. Non-Inline foam eductor
• D. IN-LINE foam eductor

Answer: (D)

Foam eduction works by drawing foam concentrate into the water stream as it flows, using a Venturi effect. The inline foam eductor is placed directly in the discharge line, so water from the pump passes through it and pulls concentrate up through a pickup tube into the stream. This arrangement is simple, rugged, and quick to deploy, giving a consistent foam ratio across a wide range of pump pressures. Because it’s integrated into the discharge path, it requires fewer extra fittings and steps than off-line or separate devices, making it the most commonly carried type on our apparatus. Venturi eductors and non-inline/off-line options exist, but they’re less convenient for regular use due to space, setup, or maintenance considerations.
