A portable, versatile foam-generating system

Our foam-generating systems are self-contained and portable

Our foam-generating systems are built to handle even the most rugged terrain and weather conditions. The Pneumatic Foam Unit (PFU) 400 is ideal for remediation projects, dredging operations and hazardous waste sites, as well as odor containment at small landfills. Freeze protection enables outdoor storage and year-round use in any climate.

Thanks to its versatility, the PFU 400 can be towed easily to the location of concern. And its quick start-up time delivers immediate emissions control.

In short: less hassle, faster solutions.
