VESDA RESTRICTOR FLOW PK10

The Xtralis VSP-871 is a pack of 10 spare flow restrictor discs, supplied as an ordering item within the Xtralis tamper-proof sampling point and refrigerated storage sampling kit ranges. These replacement discs maintain controlled sampling airflow across compatible ASD sampling assemblies.

VSP-871 provides replacement flow restrictor discs for Xtralis aspirating smoke detection sampling assemblies, ordered ten to a pack and used to maintain controlled sampling airflow. Xtralis ordering information carries the reference twice: the tamperproof sampling point documentation covering VSP-610 and VSP-620 lists the pack as spare flow restrictors, while the refrigerated storage sampling kit documentation covering VSP-860 and VSP-860-US names the same discs as flow restrictor discs. On the spares side the pack is stated compatible with the VSP-610 tamperproof sampling point for 25 mm standard pipe, and physical connection detail remains with the installation manual.
