Gulf Oil & Gas International supplies the genuine Xtralis VESDA VSP-033 (516-018-326) VLI Aspirator Filter for VESDA VLI early warning aspirating smoke detection systems to maintain reliable airflow and detection performance in high-stakes environments like oil & gas facilities, data centers, and industrial plants. This aspirator filter is installed at the VSP-032 VLI Aspirator intake and works in conjunction with the VLI Intelligent Filter (VSP-030) and Secondary Foam Filter (VSP-031) to provide multi-stage filtration of airborne dust and particulates before air reaches the optical chamber. The VSP-033 helps preserve fan performance and extend the life of the VLI detector’s internal components while supporting accurate smoke-particle measurement and stable alarm behavior. Easy field replacement restores full VLI detector performance without system downtime and is recommended as part of routine maintenance in dusty, construction-prone, or high-traffic areas. The VSP-033 is compatible with the VESDA VLI series of aspirating smoke detectors used for very early smoke detection in critical infrastructure and high-value assets.
