Demos and Free Trials

There is a lot of creative marketing to wade through when shopping for PPV fans and scene lighting. Before committing to safety tools you may rely on for 20 years or more, please push aside the fancy terminology and gimmicks: try products for yourself and compare them side-by-side and face-to-face!

Seeing is believing with our products, plain and simple. As a bonus, you’ll also experience our exceptional customer service.

All manufacturers measure performance differently, especially CFM and light output. With no consistency between measurements, published specifications can be misleading. You will never know how incredible the air flow is on a Ventry® Fan or how bright a Lentry® Light System is, nor how versatile they are, until you try one for yourself—preferably alongside or face-to-face with comparable units from other companies.

Contact us today to arrange a demonstration or possibly a free trial of our exceptional all-terrain products.

1996 letter offering a free trial to any USA fire department
Letter we mailed in 1996 to fire departments in the USA.


We have offered free trials to firefighters and other industrial customers in the USA since we began building the first fans in the late 1980s. It continues to be an easy way for potential customers to learn the benefits of our exceptionally well-engineered products.

Today, our Dealers are usually able to arrange demonstrations. However, if no Dealer is able, we are still often able to arrange a trial.

We are unable to offer free trials to individuals, but we do guarantee our products. That means you can purchase any fan or light and, if it does not meet your expectations, you may return it within 30 days for a refund of the purchase price (less shipping charges and any amount needed to cover damages incurred above normal wear and tear).
