Basement Ventilation : Cars parked in an underground parking structure emit carbon monoxide (CO) and other noxious fumes into the atmosphere. There is a need for an efficient ventilation system to remove these toxins, circulate fresh air into the car park, and assist firefighters in the case of a fire emergency. The GreenJet® series includes a range of performances ideal for parking garage ventilation. Ductless designs use jet fans to dilute and remove contaminants and control smoke. The fans move air towards the exhaust area when installed on the ceiling. This creates a continuous flow, avoiding the creation of stagnant zones where air is trapped. Vane Axial fans are used to circulate fresh air & extract exhaust air during this process.
