During every flight in the Gulfstream IV G450, fresh air is constantly supplied throughout the entire cabin of the aircraft. While many commercial planes rely on fans to recirculate cabin air, every aircraft in the fleet utilizes compressed air endlessly gathered from the sky throughout each flight. That air is cooled, conditioned, and distributed throughout the interior, nonstop. At the exact same time, air is being released from the cabin, so that every breath you take is crisp, clean, and unrecycled. Coupled with an in-cabin altitude of 6,000 feet and an 18-percent sound suppression improvement over its predecessor, the Gulfstream G450 helps you to arrive at your destination feeling your best.
