Cab Air Quality and Filtration

The Hidden Dangers in the Cab

Without specialized intervention, an equipment cab is not a safe haven; it can easily become a trap for dangerous, invisible threats that jeopardize your operators’ immediate safety and long-term health.

• Harmful Respirable Particulates: Prolonged exposure to microscopic airborne hazards like silica, asbestos, diesel particulate matter, and coal dust is a leading cause of irreversible occupational illnesses, including silicosis, black lung, and mesothelioma.
• Loss of Cab Pressure: When standard HVAC performance is choked by dirt and debris, the cab loses its positive pressure. Once pressure drops below ambient levels, the cab begins actively drawing these toxic particulates inside.
• Elevated CO2 Levels: In a sealed, enclosed cab, an operator’s exhalation rapidly spikes carbon dioxide levels, particularly when the HVAC is stuck in recirculation mode. High CO2 exposure leads to fatigue, slowed reaction times, drowsiness, and micro-sleeps, directly resulting in catastrophic site accidents.

Leading the Standard: ISO 23875 Compliance

Protecting operators requires more than standard filters; it requires engineering controls that meet rigorous international safety benchmarks. The ISO 23875 standard is the definitive global requirement for air quality control systems in operator enclosures.

As active participants in the development of these crucial standards, Climatrans intimately understands the engineering requirements necessary to achieve compliance. We design systems that meet strict ISO 23875 mandates for real-time monitoring, sustained pressurization, CO2 management, and rapid decay rates for airborne particulates—ensuring your operators are shielded from long-term respiratory illnesses.

Our Solutions: The RESPA® Cab Air Quality System

To mitigate these risks and meet ISO compliance, Climatrans integrates the industry-leading RESPA® Cab Air Quality System by Sy-Klone International. This comprehensive 3-part approach ensures maximum protection and minimal maintenance costs.

1. RESPA® CF2: Fresh Air Filtration & Pressurization

The RESPA®-CF2 is the ultimate line of defense. It combines a powered precleaner, high-efficiency filter, and pressurizer into a single, compact unit. Its powered precleaning technology maintains continuous positive pressurization, physically blocking particulates from entering the cab. Cost-effective and durable, it significantly extends HVAC maintenance intervals and filter life, slashing your labor and replacement costs.

2. RESPA® PFX & Pure: High-Efficiency Recirculation

• RESPA PFX: A compact, high-efficiency RadialSHIELD HEPA filtration unit equipped with its own blower motor. Operating independently of the machine’s AC, it rapidly recirculates and purifies cab air to meet the strict ISO 23875 decay-rate requirements. Available in 12V and 24V options for base or flange mounting.
• RESPA Pure: A standalone HEPA recirculation system perfect for any small, enclosed space. Because it is not plumbed into the factory HVAC, it provides ultimate filtration without putting restrictive strain on your existing AC components. Features easy-to-replace

3. RESPA® Advisor+ 2.0: Real-Time Monitoring

You cannot manage what you cannot measure. The Advisor+ 2.0 provides continuous, real-time monitoring of cab pressure, particulate matter (dust) levels, and CO2 concentrations. It ensures your systems are actively protecting the operator and alerts them the moment safety thresholds are breached.
