When we think of shelters, thick walls and heavy doors come to mind. However, during an emergency, what truly keeps you alive in that enclosed space is the Shelter Ventilation Unit, which cleans the outdoor air and pumps fresh air inside.

What Does a Shelter Unit Do?

• Filters Dust and Smoke: If there’s smoke, dust, or toxic gas outside, it filters them out using special filters.

• Provides Oxygen: As oxygen levels drop with more people inside, it constantly refreshes the air with fresh supply from outside.

• Pressure Control: By slightly inflating the air inside (positive pressure), it prevents contaminated outdoor air from leaking through door gaps.

In short, a shelter unit is a professional "lung" designed so you can breathe safely during the toughest times. At Serin Air, we manufacture these systems to the highest safety standards.
