The Apollo is a dual-purpose device that provides day-to-day ventilation and natural daylighting.

When the flaps are open it exhausts warm air and helps buildings stay cool. When the flaps are closed it provides weather protected daylighting. This daylighting natural ventilator is the best solution for highly efficient, low-cost natural ventilation.

The Apollo is designed for heavy commercial and light industrial applications. It has been installed at manufacturing plants, agricultural facilities, and more.

Each unit is composed of lightweight aluminum with poly-carbonate hatches. The openings are equipped with tested life-safety guards to prevent fall-ins. All units ship assembled to avoid installation problems.
