FLUSH

Dispensing Unit

The FLUSH dispensing unit is one of the few – and currently the oldest – pressurized, “Pour-In-Place” dispensing units on the market. Similar to FSI’s SLUG unit, our FLUSH unit was designed, engineered and machined to give our customers a reliable, yet cost-effective, option for dispensing rigid polyurethane foam. Manufactured of 2024 T6 aircraft aluminum and other high-quality materials, the FLUSH unit is easy to maintain, offers various outputs, and can be used with both pour and froth-based systems.

With phase-outs and regulation of common urethane cleaning solvents and other flushing liquids over the years, the demand for dispensing units like the FLUSH has decreased drastically. As a result, FSI still offers support for customers who continue to use FLUSH unit technology, but we encourage our customers to convert to our SLUG unit system when possible.
