System Sensor DST5 InnovairFlex Sampling Tube - 4 to 8 Foot Duct

System Sensor DST5 InnovairFlex Sampling Tube

Overview

The System Sensor DST5 is an InnovairFlex sampling tube designed for air sampling detection systems in duct applications. This component supports 4 to 8 foot duct runs, providing flexibility in fire detection deployment across HVAC systems. The DST5 integrates with aspirating smoke detection networks where air is drawn from protected spaces through tubing to a central detection unit, enabling early warning capability across distributed areas without requiring detectors at every location.

Key Features

• InnovairFlex construction for flexible duct routing and installation
• Supports 4 to 8 foot duct run lengths for medium-span coverage areas
• Compatible with System Sensor air sampling detection systems
• Enables centralized detection across multiple sampling points
• Reduces installation complexity in HVAC systems with flexible tubing design
• Suitable for commercial and industrial fire detection applications

Integration & Compatibility

The DST5 sampling tube integrates with System Sensor's aspirating smoke detection platform, where the tube draws air samples from protected spaces to a centralized detection unit. This architecture eliminates the need for individual detectors in each monitored area, reducing component count and simplifying wiring while maintaining continuous air sampling surveillance. The flexible InnovairFlex construction accommodates routing around structural obstacles and through tight spaces common in HVAC ductwork, making it suitable for retrofit and new construction installations where rigid tubing would be impractical.

Technical Specifications

The DST5 is rated for duct applications with sampling runs between 4 and 8 feet in length. The flexible tubing material resists kinking and maintains structural integrity under normal installation and operational conditions. System Sensor's InnovairFlex line of sampling tubes is engineered to minimize pressure drop while maintaining sample integrity, allowing the connected detection unit to analyze air quality reliably across the full length of the run without degradation in response time.

Application Suitability

The DST5 sampling tube is commonly deployed in commercial HVAC systems, data center cooling infrastructure, warehouse ceiling plenums, and industrial ductwork where early smoke detection is required. The 4 to 8 foot span accommodates typical duct segments in mid-sized protected areas. Organizations standardizing on System Sensor air sampling detection benefit from standardized component sourcing and simplified maintenance procedures across their facility footprint.

Karl Wilson

I've specified the System Sensor DST5 sampling tube in several commercial HVAC modernization projects where traditional point detectors created coverage gaps in large plenum spaces. The InnovairFlex construction of the DST5 significantly simplifies installation compared to rigid alternatives, particularly when routing through existing ductwork with irregular geometry.

Technical Highlights:

• Flexible Sampling Tube: The DST5 InnovairFlex design allows routing flexibility while maintaining sample integrity across 4-8 foot duct runs without kinking or pressure loss that would degrade detection responsiveness.
• Duct Application Range: The 4-8 foot specification covers typical commercial HVAC segments, aligning with standard ductwork sizing in facilities with 8-12 foot floor-to-floor heights.

Deployment Considerations:

• Verify duct run length against the 4-8 foot specification before ordering; runs shorter or longer require different component selection to ensure proper sample flow characteristics.
• Route the DST5 tube away from high-velocity air streams that could introduce localized pressure artifacts affecting detection accuracy.
• Secure tubing at regular intervals to prevent vibration-induced movement that may cause connection fatigue in HVAC systems with significant operational cycling.

The DST5 delivers reliable performance in standard HVAC applications and integrates seamlessly with existing System Sensor detection infrastructure. For integrators already committed to the System Sensor platform, the DST5 sampling tube is a straightforward component selection for mid-length duct coverage requirements.
