When you dive beneath the waves, every single breath matters. A dependable air compressor delivers the clean, high-pressure breathing air that keeps every dive safe and enjoyable. Monz has been New Zealand’s trusted provider of top-quality breathing air systems for over fifty years. We proudly offer world-class solutions under the names Coltri Compressors NZ and Dive Compressors NZ, each engineered to fill cylinders quickly, operate reliably and comply with the strictest safety standards.
The Coltri Compressors NZ lineup brings Italian precision engineering to your dive operation. These compressors feature dual-stage filtration combined with a built-in moisture separator that removes oil, water and particulates, guaranteeing breathing air that meets EN 12021 standards every time. Despite their power and capacity to deliver pressures up to 450 bar, their compact footprint allows installation in tight engine rooms or cabin spaces without disruption. Low vibration and noise levels keep crews comfortable during operation, while energy-efficient motors and pump arrangements reduce overall power consumption. Service panels and modular components provide quick access to filters, valves and other critical parts, cutting maintenance time and maximising uptime. When you choose Coltri Compressors NZ, you benefit from proven performance backed by Monz’s nationwide support network, including factory-trained technicians who oversee installation, commissioning and preventative upkeep year-round.
Monz’s Dive Compressors NZ range covers every possible application, from lightweight portable units to heavy-duty turnkey systems. Portable dive compressors are designed for liveaboard vessels or remote reef sites, featuring sturdy skids or handles for easy deployment and oil-lubricated pumps that run smoothly over extended service intervals. Stationary high-pressure models deliver between 300 bar and 450 bar, often combined in cascade filling systems to allow rapid turnaround on multiple cylinders. Variable-speed drive technology intelligently adjusts motor output to match current demand, reducing energy use when fewer cylinders require filling and ramping up flow when demand peaks. For resorts, training centres and large commercial operations, our custom Build-Own-Operate packages arrive skid-mounted and pre-engineered for fast on-site setup, complete with control panels that display real-time pressure, temperature and filter status. Automated safety shutdowns protect both user and equipment, while remote-access capabilities let operators diagnose and resolve issues before they escalate.
