What is PPV?

Positive Pressure Ventilation uses positive airflow to remove heat and products of combustion from a structure on a fire scene.  PPV fans come in many different sizes from 16″ blades that fit in the tightest of apparatus compartments to large scale PPVs for the largest of jobs.  There are also a variety of options to power a PPV – electric, gas, water turbine.

How to select a PPV?

First, what is the best way for you and your department to power your PPV?  An Electric motor is reliable, has a perfectly clean airstream, is generally more quiet and no fussing with gas/oil, but requires generators for set-up.  Some electric can even be used in Hazardous Locations.  Gas has a faster set up and is more powerful than electric motors, but can add by products of combustion into the airstream and requires more maintenance.  Maybe water turbine?  These can be used in explosive environments but require a 100-250 PSI water supply that should be recirculated due to the high gallonage required.

Second, what is the best size for you and your department?  How much room do you have on your truck?  What size buildings are in your jurisdiction?  How much output are you looking to get out of your fan?

Next pick a specific motor/engine.  Do you need variable speed, hazardous location motors?  What engine manufacturer do you prefer and trust?

Finally, do you need any add-ons or PPV accessories?  Maybe an LED kit?  We highly recommend the exhaust hose extension for gas PPVs to keep the airstream clear of exhaust emissions.
