What is the most efficient way to set up ventilation for a space 60 ft away?

• A. 2 fans, 4 sections of 15 ft hoses
• B. 1 fans, 2 sections of 30 ft hoses
• C. 3 fans, 6 sections of 10 ft hoses
• D. 4 fans, 8 sections of 7.5 ft hoses

Answer: (A)

Ventilation efficiency over a 60-ft run comes down to keeping air moving with enough pressure while minimizing resistive losses from hose length and joints. Two fans provide staged pressure, helping push air steadily through the entire path without overtaxing a single blower. Keeping the hose path in short, 15-ft segments reduces the chance of kinks and bending losses, and it makes routing around obstacles easier while keeping each section manageable for sealing and setup.

A single fan, or very long continuous runs, can struggle to maintain flow against friction and potential leaks over 60 ft, and more fans or longer segments add setup complexity without guaranteeing much more effective delivery. So the setup with two fans and four sections of 15 ft hoses achieves a good balance of sustained airflow, easier handling, and lower joint-related losses for a 60-ft distance.
