Coltri Mark III Silent 315 ET 300 Bar Compressor is a high-capacity cabinet breathing air unit designed for professional BA charging where noise reduction and advanced monitoring are essential. A 5.5kW (7.5Hp) three-phase motor provides 315 L/min (11.1 CFM), filling a 10L cylinder from empty to 200 bar in approximately 6.2 minutes. Operating up to 300 bar, the MARK 3 platform features automatic condensate drain, auto stop and restart, and a comprehensive control system that monitors interstage pressure, oil level, internal cabin temperature and rotation direction. Housed in a compact 730 x 1030 x 910mm acoustic cabinet, it reduces sound while allowing easy access for servicing. Dual high‑pressure outlets support flexible filling configurations. This Mark III Silent 315 ET model is ideal for dive centres, emergency services and industrial BA rooms requiring a quiet, fully featured 300 bar compressor.

A. The 300bar variant offers higher maximum working pressure while retaining 315L/min, 11.1CFM output and the same cabinet-silenced design.
A. Professional dive centres and emergency service facilities using 300bar breathing-air cylinders often specify this high-pressure configuration.
A. The cabinet helps manage noise around 82dB(A), allowing installation in technical rooms where both sound and safety must be controlled.
A. It uses a 5.5kW three-phase motor on 400V supply, similar to the 232bar version but configured for higher pressure.
A. Yes, it includes the same interstage monitoring, automatic condensate drainage and auto stop/restart control as the 232bar version.
A. It is designed for intensive duty cycles when adequate cooling, maintenance and safety checks are observed.
A. The 300bar cabinet occupies roughly 730mm by 1030mm by 910mm, balancing high capacity with a manageable footprint.
A. Yes, it can be connected to rated manifolds and storage banks to form part of a larger 300bar breathing-air network.
A. More frequent inspection of high-pressure joints, valves and safety devices is recommended to mitigate risks associated with 300bar pressures.
A. It utilises a similar pumping unit tuned for 300bar service, maintaining low-speed operation for durability.
A. It is ideal for quickly filling 10-litre and similar cylinders to working pressure in busy fill stations.
A. They should follow Coltri duty guidelines, using cooling intervals and monitoring operating parameters to protect compressor components.
