POSITIVE PRESSURE FANS
A positive pressure fan (PPF) is a building’s tool to tame smoke and fires. Thousands of cubic feet per minute of outside air gets forced inside at a high rate, pushing the existing air polluted with smoke and toxins outside through doors and cracks. It’s common to have several of these throughout the building supplying staircases and elevator shafts.
Positive Pressure Fans require very little maintenance since they will only operate during emergencies. Although it’s imperative to schedule regular inspections on them four times a year. Our Blackrock HVAC team of technicians or the property manager can co-ordinate with the building’s fire safety contractor for scheduling of these important dates. See our Professional Commercial HVAC Maintenance program offer.
