There is no sure method to detect sealants in an A/C system, but you can save time and money by installing The Removinator™ before your system becomes infected. The Removinator™ removes sealants before they can enter the machine and clog flow channels in your A/C service center. The Removinator™ also acts as a closed-loop flush system. Universally designed A/C filter works with all R134A service centers, and can be permanently installed on any A/C service equipment.
