Increased demand is placing a strain on compressor supply. To ensure stable production and to improve product lead times, we will be using different compressors in the model numbers listed in the product bulletin below. These compressors have a higher availability and will help alleviate some capacity constraints. Note that there will be new model numbers created, including one model number revision: 4TTR3036H1000PA will revert to 4TTR3036H1000NA.
