VENTRY Fans are engineered for aggressive, coordinated positive pressure attack (PPA) and ventilation (PPV; also called forced ventilation). They are valuable wherever a LOT of air is needed FAST. VENTRY brand gasoline, electric, and propane-powered fans...
- utilize all-terrain legs, aircraft style safety propellers and free-flowing guards
- push high CFM using minimal horsepower
- are known to be quiet, for better on-scene communication
- are robust without being bulky
- fit in small storage spaces
- have high-quality, narrow air cones
- may be set far back from the door (8 to 15 feet is ideal)
- may be set up off to the side, out of the way, leaving entry/exit path clear
- stand solid on uneven terrain
- straddle scene debris, clutter, hose, and other obstacles
- lift controls within easy reach
- lift fan off the ground for increased air supply to the propeller
- have open-flow guards to allow for maximum air supply to propeller
- allow fast, accurate aiming and infinite tilt angle
- lift airstream over common obstactles (porches, stairs, snow)
- are simple to operate and maintain
- are reasonably priced
- offer long life, good value and impeccable safety records.
As you navigate this site and discover VENTRY Fans, please begin with the fact that what you need from a fan is the most AIR, not the most POWER.
All fans -- and all propellers -- are NOT created equal!
If you choose efficiency and engineering over excess horsepower, you will save weight, bulk, noise, hassle, hazards and expense.
We are absolutely dedicated to providing high-quality, long-lived, fairly priced, safe, easy-to-use fans that stand up to the use and abuse of fire fighting. Our fans represent great value for our customers and are safety tools our dealers can be proud to supply to their customers.
We thank you for finding us and invite you to explore this site and learn, learn, learn. Call us if you prefer to speak with a person or have specific questions. Hint: The FAQ pages reveal a lot of the advantages. |
Why VENTRY Fans?
Ultimately, a good fan is one that moves a lot of air (usually expressed in cubic feet per minute or CFM). This is the main reason fire fighters, hot air balloonists and others choose VENTRY Fans, plain and simple. More air flow means better PPA and PPV, and VENTRY Fans with tried-n-true Honda motors move more air using less horsepower. Aircraft-style Safety Propellers and extendable legs provide a multitude of advantages over other fans and solve the problems commonly associated with PPA / PPV. Some of the most common challenges which are solved by VENTRY Fans are below. Click for info:

Consider these features of VENTRY Fans:
- State-of-the-art Smoke-Busting Safety Propellers.
- Require no new training. Same reliable, familiar Honda engines and simple, intuitive operation.
- Elevate air stream over obstacles and into elevated or awkward openings.
- Straddle obstacles, stand securely on uneven surfaces (even stairs!) and minimize “walking”
- Allow maximum flexibility in aiming airstream up and down at steep angles.
- Have low equilibrium CO levels well below OSHA warning levels.
- Have a simple design for easy field service (parts available through your local hardware store or via manufacturer).
- Are efficient so have low noise levels of 94dB (at full throttle) and won’t frustrate on-scene communications.
- Are covered by five-year warranties on all materials and workmanship.
Over the years, hundreds of fire departments have shown that our patented combination of extendable legs and smoke-busting Safety Propellers means that VENTRY Fans vastly increase fire scene and fire crew safety by delivering fresh air to victims and removing deadly smoke. They can also be used to pressurize and protect unaffected areas of a structure.
We recommend that the legs on VENTRY Fans be fully extended for every use, to maximize safety, extend the life of the propeller, and realize higher air volumes.
What challenges have you had with other fans? What problems do you need solved? Please see our FAQ pages, on which we have addressed 20 different topics relating to how VENTRY Fans will make you safer and more effective! Just click here and pick a topic...
The Basics
The whole idea of ventilation — especially for firefighting and PPV — is to deliver lots of fresh air FAST!The fan you use MUST...
- . . . allow for rapid setup on any terrain without extra crew or cribbing;
- . . . set up far from the door so as not to interfere with the entry/exit of crew and victims; and
- . . . push a LOT of air directly where it’s needed!

How long are you willing to wait?
Divide the cubic feet of the typical structure you ventilate by the CFM rating of your fan or the one you might purchase. Our 3.8-HP fan will completely replace the air in a 2000 square foot house in less than 1 minute! (See calculation at right.) Our 5.5 hp fan will do it in 33 seconds! |
