South Africa's Breathing Air Compressor Specialists

A breathing air compressor is specifically engineered to produce high-purity compressed air safe for human respiration. Unlike industrial air compressors that compress ambient air for tools or processes, breathing air compressors incorporate multi-stage filtration systems — activated carbon, molecular sieve, and CO removal cartridges — to meet EN 12021 air quality standards. They operate at much higher pressures (200–420 bar) and are manufactured to life-safety specifications. Never use an industrial air compressor to fill breathing air cylinders — the risk of CO poisoning and oil contamination is serious and potentially fatal.

Most SCBA cylinders for fire brigades and emergency services require filling to 200 bar or 300 bar. South African fire departments typically use 300 bar cylinder systems. For fire stations, we recommend the Nardi Pacific P/PG or Pacific MX depending on simultaneous fill volume and operational tempo. We size the correct system based on your specific throughput requirements.

For a busy dive centre, the Nardi Pacific P/PG (160–300 L/min) or Pacific C cabinet model are the most common choices — both providing continuous operation and fast fill times. For a charter boat or small private dive school, the portable Nardi Atlantic (60–100 L/min) at 200/300 bar is ideal. Final selection depends on your daily fill volume, required pressure, and whether portability is required.

EN 12021 is the European Standard specifying quality requirements for compressed air used in breathing apparatus. It defines maximum limits for CO, CO₂, oil vapour, water content, and other contaminants. While not yet a mandatory SANS standard in South Africa, EN 12021 is the accepted industry benchmark for breathing air quality across fire services, professional diving, and occupational health. All Nardi compressors, when fitted with the correct filtration and maintained on schedule, produce EN 12021-compliant breathing air.

Yes. We offer on-site SLA service agreements of 24, 36, 48, and 60 months across South Africa. Service includes scheduled filter cartridge replacement, oil changes, valve inspection, safety pressure testing, and air quality certification support. Genuine Nardi filter cartridges and spare parts are stocked locally in Johannesburg — no extended lead times on standard items.

Hookah diving (surface-supplied air diving) delivers breathing air through a hose directly from a surface compressor to a diver — no cylinder is required. Nardi manufactures a dedicated oil-free hookah range for this application. These systems are widely used in South Africa for hull cleaning, aquaculture, dam and pipeline inspection, and port maintenance work. The oil-free design is critical to ensure clean breathing air reaches the diver.

Nardi recommends replacing breathing air filter cartridges every 6–12 months or at the manufacturer's specified operating hour interval, whichever comes first. In coastal and high-humidity environments common in South Africa (Durban, Cape Town, Richards Bay), more frequent replacement is recommended. We supply genuine Nardi cartridges and can advise on a site-specific maintenance schedule based on your ambient conditions.

Yes. We export to Botswana, Namibia, Zambia, Zimbabwe, Mozambique, Eswatini, and Angola. We handle shipping logistics, customs documentation, and provide remote technical support. We typically supply an initial stock of filter cartridges and critical spares with the equipment to ensure ongoing serviceability in-country without dependence on regular imports for routine maintenance.

For any professional breathing air installation, we recommend: inline CO / CO₂ / O₂ monitors, automatic condensate drain kits, hour-meter packages (to track filter replacement intervals), automatic shutdown-on-filter-saturation systems, and fill panel pressure gauges. These monitoring systems are critical to maintaining EN 12021 compliance and ensuring operator safety throughout the life of the system.
