What is the most energy efficient air compressor ?

The most energy efficient air compressor really depends upon the application it is used for. It is widely recommended that when thinking about compressed air energy efficiency you should conduct an energy audit to measure your current usage and identify areas where you could make effective cost saving changes

How I can select my air compressor ?

Many parameter determine the proper compressed air sizing 

  • Application, what compressor needed for.
  • Quality of air required 
  • Power consumption 
  • Available space for air compressor
  • Actual compressed air required, compressed air utilization 
  • Future expansion.

we really urge you to ask for a professional advise from NMA team to have a proper sizing of your compressed air system for ultimate usage and cost efficient solution. 

Is it true that Variable speed drive is always the best solution for the most efficient part-load performance. ?

Not necessarily.

Inherent to their design, variable speed drive compressors have an optimum tip speed range where they operate most efficiently.

If the compressor load requirements fall outside of this range, other control options may provide the most efficient solution.

The compressor provider will need to consider the numerous application requirements in order to recommend the most efficient compressed air solution for the job.

How can I get a better quality of air ?

The quality of air compressed within your system is directly affected by ambient influences. Contaminants such as water, oil and particles are present in the air around us and get intensified in industrial settings. To improve air quality, you need to consider implementing downstream solutions such as filtration and dryers.

I have a dryer installed, so why do I get water in my air lines ?

The most common cause of water in air lines generates from either a faulty or inadequate air dryer. NMA Industrial Services Co. have extensive knowledge and experience with refrigerant, desiccant and membrane dryers and have specialist refrigerant engineers who can diagnose and quickly repair a range of common issues.

What is the Air/Oil Separator you are advise to use ?

As none of the compressor makers manufacture the Air/Oil Separator nor the Filtration we advise to use the cost effective separator taking into consideration the manufacture and the quality of the product itself as many of the filtration companies manufacture these items, but might not perform as expected and meet the manufacture working hours.

The failure of these items might lead to fatal damage of the compressor, therefore reliable source as well as full warrantee is required

We use Mikropor Separator as Mikropor is well known filter manufacture and specialized company and OEM manufacturer for well compressor makers all around the globe.

Why should I change my filter element?

To achieve the stringent air quality levels required by both modern manufacturing industry and ISO 8573-1 : 2001 the international standard for compressed air quality, highly specialized filtration materials are employed in the construction of filter elements, which have both a finite capacity and life to retain contamination. It is important to remember that when the filter life has expired, the required air quality can no longer be maintained.

Filters are installed to provide contaminant removal to a specific air quality requirement, therefore the primary reason to change filter elements should always be to maintain air quality and they should therefore be replaced every 6 months in our region ambient conditions.

What are the consequences of not changing filter elements?

• Damaged adsorption dryer beds requiring unplanned desiccant changes
• Corrosion within the compressed air storage and distribution system
• Blocked / frozen valves, air motors and pneumatic tools
• Damaged machinery causing increased production downtime
• Contamination exhausting from valves and cylinders leading to unhealthy working environments, risk of personal injury, staff absences and personal injury claims
• Inefficient production processes leading to increased manufacturing costs
• Spoiled, damaged and re-worked products
