When you consider that a good PTO driven air compressor system is worth its weight in gold, it’s hard to imagine the value of a Waterous PTO kit to your fire department. Waterous offers three models available as OEM installation or retrofit. These CAFSystems™ are water-cooled and designed to discharge water, foam solution or compressed air. They come with a Rand rotary screw airend with integral speed increasing gear set, a 1310 shaft yoke and free on-site orientation. What’s more, all units are available with Aquis™ Foam Proportioners.
