Coltri Open
Great performance, even when charging.
Open is designed to meet the professional needs that require large charging capacities in hot, poorly ventilated, or tropical countries. It is equipped with 4 front filling connections for high-pressure hoses, an intuitive control panel, and an electric motor. The pumping unit, chosen from the 4 most powerful options, is exposed in the rear part of the structure to ensure a better cooling cycle. For extended filter life, the Tornado high-pressure dryer is recommended. Optional features include the Presec system for filter saturation control or the SAM system for multigas analysis and a remote charging panel.

Purification at the highest level.
Placed after the last compressor separator and before the pressure holding valve, the Hyperfilter purification system enables reliable treatment of breathing air according to DIN EN 12021¹ when using original filter cartridges. The separator present between the 2nd and 3rd stages of the purification circuit allows for the extraction of the greatest possible humidity. The filtering capacity with inlet air at 68°F and 2900 psi is 151,916 cubic feet.
