Hybrid Ventilation System

pressure gravity system

A Hybrid Ventilation system® is ideal for buildings with lower ceiling height and/or less heat emanating from the process. It utilizes natural ventilation and powered ventilation together. We like to think of it as natural ventilation with an extra boost from powered ventilation.

One example is a Pressure Gravity system which uses passive natural ventilation for exhaust and powered sidewall fans for enhanced air intake.

Hybrid Ventilation Systems utilize a complete building approach to achieve the right solution for the given facility. By combining ventilators and exhaust fans in a way that works with the buildings natural air-flow, more effective and efficient systems can be designed.

This allows for a more comfortable environment where the plant personnel is working without wasting energy to cool spaces that don't need it. State-of-the-art computer control systems are often used determine the right conditions and adjust the system accordingly. With a Hybrid System, Natural Ventilation Solutions can be put to work in facilities where it may have previously been impossible.

Benefits of Hybrid Ventilation

  • Achieve the benefits of natural ventilation when possible
  • Cool naturally as often as possible
  • Improve indoor air-quality
  • Reduce Operation & Maintenance Costs
  • Remove humid air, smoke, and fog
  • Increase fresh air at the operating floor
  • Improve personnel comfort
  • Increase evaporative cooling effect
  • Create a positive pressure environment
  • Self-Adjusts to changes in Air-flow
  • Target Building Hot Spots & direct intake air to where it’s needed

Unlike a roof exhaust fan system that requires time-consuming, costly, and tedious roof modifications and maintenance hours each time more air is needed, a Pressure Gravity System® provides the ability to easily increase air-flow capacity.
