Research and shop around for a type of fan called a centrifugal blower or utility blower. These fans are designed specifically for entire space ventilation. They sound like tiny jet engines. The same fans that inflate bouncy fun houses or the fans you sometimes see on a storefront wet floor during a rainy day to blow dry. Output rates of small units 100 to 500cfm (cubic feet per minute) will replace all air inside a 2-car garage space every hour. Mid range blowers 600-900cfm will replace that same air space every 5-10min (approx. 6x per hour). Higher velocity blowers >1000cfm will clear an entire 1-story house (typically for HVAC or factory use) and is more efficient and quieter than the biggest attic fan style unit.

After you have bought the raw power of air movement, then experiment with positive pressure and negative pressure flow setups (suck vs. blow). And then finally other per room or per window configurations as needed.
