AirSense Quick release airline valve

When the aspirating smoke detection system is installed in a dirty or dusty environment, the sampling pipes and sampling holes may get obscured over a period of time by various airborne particles. It is recommended that the sampling pipes and holes be cleaned by blowing them through with low pressure, compressed air in the reverse direction. The connection of the compressed air to the sampling pipe and the release of excess air at the end of the sampling pipe can be cumbersome but with the Quick Release Airline Valve (9-30976), the ¾” Large Check Valve (9-10978) and ¾” Large 2 Way Ball Valve (9-10980) this no longer needs to be the case. The quick-release airline valve should be installed close to the detector. During maintenance, the detector can be switched-off and the valve closed to prevent any damage to the detector during the cleaning process. The low pressure compressed air can now be easily connected to the quick release. At the far end of the sampling pipe the ¾” large check valve or ¾” large 2-way ball valve can be used. The check value is the easiest to use as it automatically opens to release excess pressure during the cleaning process and does not require human interaction. In some cases, where the check valve might not be suitable, then the 2-way ball valve can be used to manually open the far end of the sampling pipe.
