Low Pressure Breathing Air Compressors
Nuvair has been manufacturing low pressure breathing air systems for the working diver for more than 30 years. We offer standard and custom configurations for a wide variety of stationary and portable installations. Nuvair can create customized compressors to meet your specific needs and guide you through the many configurations that the compressor packages can be purchased in. Our salesman understand that needs, budget and comfort level lead to the choices one makes on the type, brand and model of compressor you will be using. Nuvair offers custom configurations of "tried and true" compressor brands combined with electric, gas or diesel motors of the same caliber.
Our commercial diving low pressure compressors are broken down into three categories, Light Duty, Medium Duty, and Heavy Duty. This web page is designed to guide you through the different compressor packages and options available to you. We realize that not all options are pictured and described which is why we encourage you to call us and help us create the perfect compressor package for you.
All Nuvair compressor packages are manufactured in-house and tested before leaving Nuvair. From start to finish our technicians are making sure your package is inspected, tested and delivered on time.

Light Duty Compressors
Our light duty commercial compressors are ideal for shallow work areas in depths of 20 ft. (7 Meters) or less. Lightweight, low cost and portability are the main reasons for choosing a light duty compressor. You can choose between oil free or oil lubricated compressor. The oil free designs are light and easy to move around and do not require some of the options necessary with oil lubricated compressors to meet OSHA Regulations. Diver air filtration does not come standard with our light duty compressors and is an important option to discuss and make sure you have on any breathing air compressor system.
One final consideration when purchasing a light duty compressor would be your planned use. If you plan to use the compressor for continuous duty work or have multiple divers in the water it will be important to get a compressor that meets the demands of the CFM and pressure you will need. As always give us call and we will guide you through the decision process and be sure your purchase meets your requirements.
19 to 23.7 CFM @ 145 PSI
23 CFM @ 145 PSI
19 CFM @ 175 PSI (528 L/m @ 12 bar)
Medium Duty Compressors
These low pressure compressors are continuous duty compressors that can support multiple divers in shallow water or a single diver at depth. Medium duty compressors are 18 CFM to 50 CFM and often used for inland diving or on small boats. We use Champion, Quincy and Rotair blocks with either electric motors, gas or diesel engines to build these compressors for working divers.
19 CFM @ 175 PSI (528 L/m @ 12 bar)
20 CFM @ 175 PSI (538 L/Min @ 12 bar)
20 CFM @ 175 PSI (538 L/Min @12 bar)
20 CFM @ 175 PSI (538 L/min @ 12 bar)
35-49 CFM @ 175 PSI (991-1387 L/min @ 12 bar)
19 CFM @ 175 PSI (528 L/min @ 12 Bar)
Heavy Duty Compressors
Deep diving, heavy duty, off shore, words that lead into 50 CFM and higher compressors. Used for offshore diving, putting multiple divers in the water and simply built to last. The Quincy 5120 is our primary block for these packages producing 85 to 95 CFM. For more CFM we are now supplying rotary screw packages into the hundreds of CFM.
90 CFM (2560 L/min)
90 CFM @ 175 PSI (2560 L/min @ 12 bar)
95 CFM (2690 L/min)
95 CFM @ 175 PSI (2690 L/min @ 12 bar)
The series of FIAC silent reciprocating compressors of 0.75 to 10 HP are the outcome of recent technological research and design. The SCS model features a special 30 soundproofing system made up of a metal soundproof panel, painted with epoxy paint, which guarantees remarkably low noise levels plus the total elimination of vibrations (acoustic pressure < 70 dB).
The main technical characteristics are as follows:
- Electro-mechanical synoptic control panel with start button, emergency button, hour meter and pressure gauge.
- Supplementary ventilation system, controlled remotely by means of a thermostatic probe.
- Electric cabinet and electric motor with protection rating IP55.
- Shock-absorbing system with 4 attachment points.
- Cooling radiator.
- (upon request) Freon dryer with standard electronic panel for controlling and maintaining the dew point, timed condensate discharge and display of the operating status.
