BREATHING AIR COMPRESSORS

Coltri, a quintessentially Italian company, started in 1963 with high-pressure scuba diving compressors and has since expanded into firefighting and industrial gas compressors. Our commitment to ongoing design and manufacturing advancements has established us as industry leaders.

We use the latest technologies, including robots and digital machining centers, to produce reliable and efficient products. Each component is meticulously designed, engineered, and assembled in-house, meeting rigorous quality standards. Our use of precision tools like ZEISS® ensures top-notch performance and accuracy.

Recognized globally for our quality, we strive to enable our customers to overcome challenges and explore new possibilities, whether for personal, industrial, or emergency applications.

LP Rotary Silent 600 This setup features an industrial screw compressor that provides air at 12 bar pressure to a membrane, which separates nitrogen and oxygen, achieving up to 40% oxygen. The oxygen-enriched air can then be compressed to 232 bar when paired with a high-pressure compressor. The oxygen concentration at the output can be adjusted between 22.4% and 40% using a valve located on top of the compressor. An oxygen analyzer is included to ensure the correct oxygen level and to make any necessary adjustments using the designated valve.

LP ROTARY SILENT 600

This system includes an industrial screw compressor that supplies air at 12 bar pressure to a membrane, which separates nitrogen from oxygen, allowing for an oxygen concentration of up to 40%. The enriched air can then be compressed to 232 bar when used with a high-pressure compressor. The oxygen concentration at the outlet can be adjusted from 22.4% to 40% using a valve located on the top of the compressor. An oxygen analyzer is provided to check the accuracy of the oxygen level and make adjustments with the appropriate valve.

LP ROTARY SILENT 300

This system features an industrial screw compressor that supplies air at 10 bar pressure to the Parker® membrane. The oxygen concentration at the output can be adjusted from 28% to 38% using a valve located on the front of the compressor. When paired with a compressor equipped with the 315 (MCH 16) pumping unit, it can produce 32% Nitrox at pressures up to 232 bar. An oxygen analyzer is included to check the accuracy of the oxygen percentage and allows for adjustments via the designated valve.

LP ROTARY SILENT 250

The OPEN model is designed to address professional demands for high charging capacities in hot, poorly ventilated, or tropical environments. It features four front filling connections for high-pressure hoses, an easy-to-use control panel, and an electric motor. The pumping group, selected from the four most powerful options, is positioned in the rear housing to enhance cooling efficiency. For extended filter lifespan, the Tornado high-pressure dryer is recommended. Optional features include the Presec system for monitoring filter saturation and the SAM system for multigas analysis and a remote charging panel.

OPEN

The SUPER SILENT model is distinguished by its exceptional noise reduction. It is user-friendly and offers comprehensive monitoring capabilities through its control systems, which track various compressor operations. Standard features include two connections for high-pressure hoses, an interstage pressure gauge, oil level and internal cabin temperature control, a rotation detector, an electric motor, automatic condensate drainage, and auto-stop. You can select the most suitable pumping group to meet your specific needs.

SUPER SILENT

Practical and lightweight, the ERGO model blends durability with excellent operational efficiency. It features two types of pumping units and can be powered by either electric motors or Honda petrol/Kohler diesel engines. The compressor includes a monitoring panel with interstage pressure gauges, an adjustable pressure switch with auto-stop, automatic condensate drainage, and rotation direction control. It also has two high-pressure hose connections (ranging from 232 to 330 bar) and a Maxifilter filtration system. A remote charging panel is available as an optional accessory.

ERGO

The Mark III Silent model is equipped with control systems to efficiently oversee various operations, including interstage pressure, oil level, internal cabin temperature, and rotation direction. It features two connections for high-pressure flexible hoses and comes with electric motors and robust pumping units. Standard features include an automatic condensate drain and an electrical panel for managing automatic compressor shutdown. Optional features include a remote charging panel.

MARK III SILENT

SMART breathing air compressors are an advanced version of the STANDARD model, which is renowned for its global popularity and high sales. These compressors feature two connections for high-pressure hoses and come with options for either single-phase or three-phase electric motors. They are built with durable pumping units and a compact frame with handles to facilitate transport. Available options include external refilling panels, an electrical display with automatic condensate drainage, and an auto-stop pressure gauge.

SMART ELECTRIC

Coltri’s Mini SILENT series of breathing air compressors, featuring 100 and 125 l/min pumping units, are designed to operate with minimal noise while maintaining high performance. Their spacious frame accommodates a Maxifilter filtering system. These compressors come with options for single-phase or three-phase electric motors and include an integrated control panel with an hour meter. Standard features also include an automatic condensate drain and auto-stop.
