Coltri Open High-Capacity Compressor – Designed for Tough Aussie Conditions

In the demanding environments of mine sites and emergency service operations, performance under pressure isn’t optional—it’s essential. The Coltri Open Compressor is engineered for high-volume SCBA cylinder refilling, even in hot, poorly ventilated, or tropical conditions where lesser systems can falter.

With its open-frame design, this unit promotes superior airflow around its powerful pumping system, delivering efficient cooling and reliable output, even in Australia's harshest above-ground conditions.

Key features include:

• Four front-facing high-pressure filling connections for fast, efficient charging

• Intuitive control panel for ease of operation

• Heavy-duty electric motor paired with one of Coltri’s four top-performing pumping units

The rear-exposed pump layout enhances cooling performance, making it ideal for extreme climates and continuous operation.

To ensure cleaner air and reduce maintenance, the Tornado high-pressure dryer is recommended. Optional upgrades include:

• Dryer
• SAM Sensor (CO, CO2, H2O)
• CO Gas Analyser
• Fill Pressure 300bar/350bar
• Auto Start

ADD ON ITEMS

Whether you’re on a mine site or coordinating emergency response, the Coltri Open keeps your breathing air supply cool, clean, and dependable—no matter the heat.
