The VS1C automatic air vent is designed to automatically discharge/release air trapped in water-carrying pipes during water transport. It also automatically discharges the air that was entrained in the water during operation and has subsequently been separated and collected in specific locations in the piping.
The three types of cautionary items above are very important for safety: be sure to observe all of them as they relate to installation, use, maintenance, and repair. Furthermore, TLV accepts no responsibility for any accidents or damage occurring as a result of failure to observe these precautions.
