Preparing for the End of Service for TSI PortaCount: Why Many Organisations Are Transitioning to AeroFit

TSI has announced a significant change in support for two widely used respirator fit testing instruments: the PortaCount 8030 and 8038.

According to the announcement, 2027 will be the final year these devices receive service support, with calibration services scheduled to end in 2030. For many safety, industrial hygiene, and occupational health teams, this timeline marks an important planning milestone.

While these dates may feel distant, they are already prompting organisations to evaluate their long-term respiratory protection programs. Fit testing is a critical part of workplace safety compliance, and continuity of reliable equipment is essential. The good news is that transitioning forward does not require starting over or abandoning familiar technology workflows. Solutions such as AeroFit are designed to bridge this gap, offering continuity with meaningful modernisation.

What the End of Service Means for Current Users

The PortaCount 8030 and 8038 have been widely used for quantitative respirator fit testing across industries such as healthcare, construction, manufacturing, and emergency response. As these systems age out of manufacturer support, organisations will face several challenges:

• Limited access to manufacturer servicing after 2027

• Increasing difficulty obtaining long-term calibration support beyond 2030

• Higher risk of downtime due to aging hardware components

• Potential workflow disruption if devices fail without repair pathways

Maintaining consistent calibration and traceable records becomes increasingly important as devices reach end-of-support status. This is why many safety professionals are beginning to proactively evaluate replacement or upgrade strategies now, rather than waiting for service gaps to appear.

Introducing AeroFit: A Modern Path Forward

AeroFit has emerged as a next-generation fit testing solution designed specifically for organisations moving beyond older particle counting systems. Rather than requiring teams to relearn entirely new workflows, AeroFit builds on familiar testing principles while introducing updated hardware and software capabilities. 

One of the key advantages is continuity. AeroFit uses the same foundational technology that 8030 and 8038 users already understand, helping reduce training time and transition friction. At the same time, it introduces a more streamlined, modern experience designed for today’s safety programs.

AeroFit Key Benefits

Organisations evaluating their next step are increasingly drawn to AeroFit for several practical reasons:

• Revolutionary APC Technology
  AeroFit’s advanced APC system delivers precise, repeatable, and stable results, offering enhanced accuracy and reliability over legacy particle-counting models.

• Modern, Compact Design
  Lightweight and portable, AeroFit is designed for ultimate convenience, allowing effortless setup and use across both fixed and mobile testing environments.

• Quiet and Efficient Operation
  Engineered for near-silent performance, AeroFit is ideal for clinical, laboratory, and office environments where low noise levels are essential.

• True Flexibility with Battery Power
  Optional battery operation provides complete mobility, even without mains power.

• Standalone Functionality
  Operates independently with no need for a tablet, Bluetooth, or Wi-Fi, giving users greater flexibility and ease of use.

• Seamless System Integration
  AeroFit shares the same battery packs, adaptors, and OHD Logic cloud software as the QuantiFit2, simplifying management and reducing operational costs.

• User-Friendly Colour Touchscreen
  A clear, intuitive interface enhances operator experience and reduces training time.

Trade-In and Transition Support

The planned end of service for the PortaCount 8030 and 8038 represents a clear turning point for respiratory protection programmes worldwide. While these devices have provided reliable service for many years, the transition to newer platforms is now an inevitable part of long-term programme planning.

AeroFit is not simply a replacement; it is a step forward in usability, connectivity, and lifecycle sustainability. By planning ahead, organisations can avoid disruption, maintain compliance, and improve operational efficiency.

For most teams, the most effective approach is a structured transition: continuing to operate existing equipment while gradually introducing newer systems. This ensures continuity today while building a more resilient and future-proof testing programme.
