Maintenance and repairs must only be carried out using original spare parts and qualified technicians. 

Nuvair cannot be held liable for any damages caused by failure to observe this rule. The compressor is 

guaranteed as per the contractual agreements made at the time of sale. Failure to observe the 

regulations and instructions for use contained in this manual shall render the warranty null and void.  

 

1.6  Purpose of the Machine 

 

This high-pressure compressor

 

has been designed and built for the purpose of producing breathing air by 

drawing it from the surrounding environment. The surrounding environment air must be free from any harmful 

fumes or contaminates. The air is pulled through an intake air filter, compressed, and passed through 

breathing air filtration before it is stored in tanks constructed to contain air at high pressure. The compressor 

can also be used for the pumping of gases:  

 

  Nitrogen  

  Helium 

  Nitrox mixtures up to 40% 

 

Any other use is inappropriate. The manufacturer cannot be held liable for any personal injury or damage to 

objects / the machine itself caused by improper use.  

 

 

 

 

 

Use only tested, certified storage tanks: do not exceed the working pressure indicated on them. 

 

Drain air from tanks before filling when tanks have not been used for an extended period.  

 

Use the compressor in areas free from dust, risk of explosion, corrosion, and fire. 

 

Improper use could have serious consequences for the user. 

 

Do not disconnect the hose from the fittings or the clamp when under pressure. 

 

Change the air purification filters regularly as described in section 13.0.  

 

Drain the condensate regularly as illustrated in section 13.2: Condensate Discharge.  

 

The power must be disconnected and locked out before carrying out any cleaning or maintenance 

tasks.  

 

Never pull a plug out by tugging the cord. Make sure the cord is not bent at a sharp angle and that it 

does not rub against any sharp edges. Use of extensions is not advised.  

 

Never operate the compressor when the power cord is damaged. 

 

All routine and unscheduled maintenance tasks must be carried out with the compressor at a 

standstill, the electrical power supply disconnected or locked out and all lines are depressurized.  

 

After switching off the compressor wait about 30 minutes before carrying out any maintenance 

tasks to prevent burns.  

 

To ensure maximum working efficiency, Nuvair

 

has constructed the compressor with carefully selected 

components and materials. The compressor is tested prior to delivery. Continued compressor efficiency over 

time will also depend on proper use and maintenance as per the instructions contained in this manual.
