Purge has been formulated to contain the industry’s highest pressure, more that 3 times of the closest competitor. Higher pressure allows the contractor to use less Purge when compared to other brands. Vapco’s proprietary formula also contains special acid and moisture absorbing abilities to ensure the trapping and removal of more system harming contaminants. Purging systems when necessary should be an integral standard for any major system repair, retrofit, or change-out and can cut down and avoid the need for time consuming repairs and repeat visits. Pair with one of Vapco’s Performance Xpress Injects for even better long term protection and system improvement.
