Atlantic G100 vs Atlantic P: What’s the Difference
| Series | Engine | Power supply | Application |
|---|---|---|---|
| Atlantic G (G100) | Petrol Robin/Subaru EX17, 6 HP | Petrol — autonomous | Field use, remote locations, no mains power |
| Atlantic P 60 | Single-phase electric, 2.0 HP (1.5 kW) | 220 V / 50 Hz | Stationary use, low volume |
| Atlantic P 100 | Single/three-phase electric, 3.0 HP (2.2 kW) | 220 V / 380 V | Stationary use, high demand |
Atlantic G100 is the only fully autonomous model in the series. The Robin/Subaru EX17 engine requires no external power supply and starts reliably
across a wide temperature range — ideal for use on a boat, at a dive site, or in a fire station without three-phase power.
Design Features of the Atlantic G100
4-Stage Compression Block — Reliability at Extreme Pressure
Compressing air to 330 bar in one or two stages is physically impossible without critical overheating and efficiency loss. Nardi’s 4-stage design
splits the process into four sequential stages with intercooling between each pair. This reduces the thermal load on each stage, minimises piston ring wear and extends block service life. Cylinders are aluminium and deliberately left unpainted — the bare metal surface maximises heat dissipation.
Intercooling System
Between each pair of stages, compressed air passes through cooling coils made of aluminium and stainless steel. Lowering air temperature between
stages improves compressor efficiency and is a prerequisite for achieving DIN EN 12021 breathing air quality.
ATL Filter Purification System
Two-stage purification: a built-in separator removes moisture and oil mist after compression, then the ATL cartridge with silica gel and activated carbon brings the air up to breathing quality — no odour, no oil traces, no excess moisture. Air meets DIN EN 12021 / UNI EN 12021:2014.
Marine-Grade Corrosion Resistance
The aluminium frame has an epoxy powder coating and hardware is made from stainless steel. This combination allows the Atlantic G100 to be operated in high-salinity environments — on yachts, dive boats and coastal locations — without corrosion from salt air exposure.
Robin/Subaru EX17 Engine
The Robin EX17 is an industrial single-cylinder four-stroke petrol engine from Japan, 6.0 HP, widely used in generators, pumps and high-pressure
compressors for its reliability and simple maintenance (oil change + air filter cleaning). Delivers confident cold-start performance — critical for outdoor use.
Available Options and Accessories
- Auto-stop and automatic condensate drain — compressor stops automatically at set pressure and drains condensate during operation.
- Dual pressure 225 / 330 bar — optional valve for filling cylinders at both 225 and 330 bar alternately or simultaneously without component changes.
- Hour meter — precise tracking of operating hours for timely maintenance and filter replacement.
- Transport kit — wheels and folding handle for one-person portability.
- Eco condensate collection tank — collects condensate to prevent environmental contamination near water.
Applications for the Nardi Atlantic G100
Scuba Diving: Filling Cylinders and Tanks
The Atlantic G100 delivers breathing air to DIN EN 12021 standard. 330 bar covers all standard diving cylinder formats (200, 232, 300, 330 bar). A standard 12-litre cylinder fills to 200 bar in approximately 24 minutes. The petrol engine’s autonomy allows use on a boat or at a remote dive site with no electrical supply.
Fire Services and Rescue Teams
Refilling self-contained breathing apparatus (SCBA) in the field — at fires, accidents and search-and-rescue operations. DIN EN 12021 is the mandatory standard for firefighter breathing air. Petrol autonomy guarantees operation even during complete power outages.
PCP Airguns: Hunting and Target Shooting
PCP (Pre-Charged Pneumatic) air rifles require 200–300 bar. The Atlantic G100 at 330 bar is the optimal choice for filling PCP rifles in the field, at hunting grounds and at shooting ranges without power sockets. 100 l/min delivery means fast filling without long waits.
Paintball and Airsoft
Filling CO₂ and HPA (High-Pressure Air) cylinders for paintball equipment. The G100’s autonomy allows use directly on the playing field or at away events without stationary power infrastructure.
Industrial and Laboratory Applications
Laboratory rigs, test benches, cryogenic systems and any application requiring ultra-high-pressure air with certified gas quality. ISO 9001:2015 certification confirmed by TÜV SÜD.
Nardi Compressori: Italian Quality Since 1965
The Nardi Compressori plant in Montecchio Maggiore, Italy has specialised exclusively in high-pressure breathing air compressors since 1965.
This single-sector focus gives Nardi deep expertise in this niche. Every unit undergoes individual testing before dispatch. Certified to ISO 9001:2015 (TÜV SÜD) and DIN EN 12021.
Full design and assembly cycle in Italy.
Power Unit Options: Atlantic Series
In addition to gasoline engines (such as the Robin/Subaru EX17), the Atlantic compressor series is available with electric drives, which are designated by the “P” index.
The following motor types are available for the series:
-
Single-phase electric motors: Installed on the Atlantic P 60 and Atlantic P 100 models. These are designed for use with standard electrical grids and have a power output of 2.0 hp (1.5 kW) or 3.0 hp (2.2 kW), respectively.
-
Three-phase electric motors: Available for the Atlantic P 100 modification. This motor delivers 3.0 hp (2.2 kW) and is intended for professional or industrial use.
Thus, while the Atlantic G model is fully autonomous thanks to its gasoline engine, the Atlantic P versions are oriented toward operation in locations with access to the power grid. General Nardi product descriptions also mention the possibility of using DC motors (battery-powered), but specific data sheets for the Atlantic series list only single-phase, three-phase, and gasoline options.
Frequently Asked Questions about the Nardi Atlantic G100
What does «G» in Nardi Atlantic G100 stand for?
«G» = petrol engine (Gasoline). Atlantic G100 is fitted with Robin/Subaru EX17, 6.0 HP — fully autonomous, no mains power needed. Electric versions are designated «P» (Atlantic P 60, Atlantic P 100).
Is it suitable for filling scuba diving cylinders?
Yes. Air meets DIN EN 12021 breathing air standard. ATL filter removes moisture, oil and contaminants. 330 bar covers all cylinder formats. A 12 L cylinder fills to 200 bar in ~24 minutes.
Can 225 and 330 bar cylinders be filled without changing components?
Yes, with the optional dual-pressure valve, cylinders at 225 and 330 bar can be filled alternately or simultaneously.
How often should the ATL filter cartridge be replaced?
Monitor the silica gel colour indicator in the ATL cartridge and the hour meter (optional accessory). Replacement ATL cartridges are available from Acvatron.
Is the Atlantic G100 suitable for PCP airguns and paintball?
Yes. 330 bar and 100 l/min are ideal for PCP airguns (200–300 bar), HPA paintball cylinders and airsoft reservoirs. Petrol autonomy allows use at shooting ranges and in the field without a mains supply.
