VIDEO: Blow-off between 2 PPV fans

VENTRY^® Fans...

The significant and numerous benefits of combining cutting-edge propeller technology, an open-flow guard, and our patented three-legged design are explained in later pages of this site. (See pages on Legs, The Propeller, and Open-Flow Guard using the menu above).

Additionally, VENTRY Fans...

• allow for easy one- or two-person transport and setup (see video and photos)
• set far back from the door/target (8 to 12 feet is ideal)
• are quieter than conventional fans because of the propellers and guards (more details are on the Solved/Quiet page)
• have low equilibrium CO levels well below OSHA warning levels
• have a simple design for ease of operation and easy field service
• are reasonably priced (see prices)
• offer long life, great value and impeccable safety records (see propeller safety too)
• have many models and options from which to choose to meet your specific needs and budget
• utilize reliable, familiar Honda engines
• offer several options, including Entry Point Lights and several different Wheel options, some even have Stair Skids (see the options page)
• are available powered by gas (petrol) or electricity
• are backed by long warranties and lifetime factory support (see warranty details)

PPV Fan Shopping Checklist

We try not to make claims about our products that can not be scientifically measured or proven; unfortunately, we see many claims using words like “highest, greatest, best, safest” and other words used to describe products which can not be proven. Please consider the following points before deciding which fan is best for you. Even poor performing fans last a very long time. Doing your research before you purchase may save YEARS of unnecessary hassles and hazards.

• Question how manufacturers determine their CFM values! There are many ways of measuring air volume and many variables in the process; at this time, there is no consistency in the industry. We verify our fans' air volumes using thrust! Newton's Third Law of Physics provides a reliable way by which anyone can measure fan performance. Use this Law to easily compare fans! Customers should never rely solely on manufacturers’ CFM values.

• When considering price, make sure you consider value and prioritize air volume over horsepower. Calculate the cost per CFM (cubic feet per minute). Air volume is what you need from a ventilation fan, not a big motor! With some manufacturers, sadly, horsepower and output do not always directly correlate.

• Consider the air volume you get per horse of engine power. Excess horsepower is used to compensate for inefficient propellers. With VENTRY, you get more air using lower horsepower motors, so you save weight, size, carbon monoxide, noise and money.

• Get as large a fan as you can, based on space and personnel. More air is always better than less when it comes to ventilation. If you have the space and manpower, we always recommend going with the largest fan possible; however, it must fit in the truck. Check dimensions and compare similar-sized fans.

• Please compare all-terrain VENTRY Fans with conventional ground-huggers and consider your particular needs.
