FAQs

What gases is the 44AAV24 booster designed to boost?

Model 44AAV24 is designed for air, nitrogen, or other inert gas pressure boosting.

What are the key engineering specifications provided in the manual?

The manual lists maximum gas discharge pressure, gas temperature range, maximum cycle rate, gas displacement per cycle, maximum gas displacement per minute, boost ratio guidance, and inlet/discharge connection types.

How should the booster performance curves be used?

The graphs show performance when drive air pressures are held constant while gas supply pressures vary; use them to size the 44AAV24 booster for the given application.
