Pulse-Bac® units are made for the rugged conditions of a job-site. We don’t cut cost with molded plastic tanks, cheap electrical components and off-shore manufacturing. With tanks made of 16ga. cold-rolled U.S. steel and a steel assembly covered with by a high impact ABS plastic hood, Pulse-Bac® is made to keep working even in the most punishing conditions. Even details like wheels are heavy duty, non-marking polyurethane casters, instead of molded plastic wheels on thin spindles. Add the fact that every Pulse-Bac is assembled by hand in our facility in Tulsa, Oklahoma and you’ve got quality you can’t beat.
