A typical plant that has not been well maintained will likely have a leak rate equal to 20 percent of total compressed air production capacity. On the other hand, proactive leak detection and repair can reduce leaks to less than 10 percent of compressor output.

In addition to being a source of wasted energy, leaks can also contribute to other operating losses. Leaks cause a drop in system pressure, which can make air tools function less efficiently, adversely affecting production. In addition, by forcing the equipment to run longer, leaks shorten the life of almost all system equipment (including the compressor package itself).

Increased running time can also lead to additional maintenance requirements and increased unscheduled downtime. Finally, leaks can lead to adding unnecessary compressor capacity.

How do you estimate the Size of Air Leaks?

Answer: It’s not very hard.  We’ll use the “TIME METHOD” to estimate percentage % of loss due to air leaks in your plant.

1-  Turn OFF all air operated end-user equipment. 2-  Start your air compressor and let it cycle 3 times 3-  Time the OFF-LINE / UNLOAD TIME (not pumping time) using your watch. (Example: 5 minutes) 4- Time the ON-LINE / LOAD TIME (pumping time) using your watch. (Example: 2 minutes) 5- Calculate total percentage of air leaks as follows:

Add the OFF / UNLOAD and the ON / LOAD times together:

Example: T(5 minutes)  +  T (2 minutes)= 7 minutes Divide  ON / LOAD time T (2 minutes) by the total minutes: 2 ÷ 7 = 0.29

The result tells you 29% of your air compressor’s CFM’s are maintaining your AIR LEAKS. This would mean that you are losing almost ONE THIRD of your compressed air to air leaks.

OSHA-Its-the-law osha_valve
The OSHA Safety Standard Regulation 29CFR CHXVII Paragraph 1926.302(b)(7) states:   All hoses exceeding 1/2-inch inside diameter shall have a safety device at the source of supply or branch line to reduce pressure in case of hose failure.

Prevent dangerous air hose whips and accidents.   Protect your most important assets: Your employees and their equipment.   OSHA COMPRESSED AIR SAFETY SHUT-OFF VALVES offers simple but efficient protection to pneumatic systems in the event of a broken compressed air hose or pipe.

Another OSHA guideline publication states:  “Hoses, cables, and other equipment shall be kept clear of passageways, ladders and stairs.” 

OSHA says reduce your slips, trips and falls. Slips, trips and falls constitute the majority of general industry accidents, which cause 15% of all accidental deaths, and are second only to motor vehicles as a cause of fatalities. The OSHA standard for walking and working surfaces apply to all permanent places of employment, except where only domestic, mining, or agricultural work is

Consider adding reels to increase safety & efficiency with your electrical cords, welding cables, air hose, oil, grease, liquid/water or fuel hoses.  This could be one of your most effective equipment additions you’ll ever make…as well as one of the safest!

Here are 5 Reasons to use Hose Reels:

  1. Increase Efficiency Hose reels makes all your hose handling more efficient. An organized, clean workplace is proven to be more efficient.
  2. Provide a Safer Work Environment Hose reels decrease you chances of injuries from tripping hazards.  Reduce accidents and insurance expense:  Slips, trips and falls are the leading cause of work stoppage in industry. Reels can help you meet OSHA Safety Requirements.
  3. Protects Equipment Hoses (and cords) last five times longer when stored on a reel. This can save you from replacing hoses as often. Keep hose off the floor where it can be damaged by trucks, doors, and dropped tools.
  4. Stop Leakages Hoses on reels can reduce the threat of expensive leakages of air and any fluids carried through your hoses.
  5. Increase Productivity Locating your hoses quickly- when and where you need them- can increase productivity.  All these factors help improve your work environment, which saves you time, equipment and money. ____________________________________________________________

Reels are suitable for many applications – such as industrial, automotive, marine, chemical, welding, petroleum, food processing, aviation, and electrical.

Reels are used to transfer air, water, motor oil, transmission fluid, grease, gear oil, anti-freeze, diesel fuels, welding gases, fuel oil, liquid pesticides, fertilizers, detergents, hydraulic oils, cutting oils, printing inks, solvents, chemicals, and blacktop sealers.

Probably one of the largest uses of hose reels is for Compressed Air. Compressed air is clean, readily available, and simple to use. As a result, compressed air is often chosen for applications for which other energy sources are more economical.  Inappropriate uses of compressed air include any application that can be done more effectively or more efficiently by a method other than compressed air.

Don’t WASTE your Compressed Air. Check your facility for wasteful and perhaps even unsafe uses of compressed air. Bottom Line:   Invest in durable, quality reels that make hoses, cords and cables more productive, keep them easily accessible and make them last longer.

Whether you are the business owner or the one who does equipment maintenance…you’ll save time and money by upgrading from mineral-based oils to quality Synthetic Air Compressor Lubricants.

If you are the business owner – you’ll love saving money because you upgraded to synthetic oil!

If you are the one who changes the oil – you’ll be glad to make a lot less oil changes!


Eight proven benefits from upgrading to quality Synthetic Air Compressor Lubricants in Reciprocating Type Compressors:

1- Saves 7%-10% in Electrical Usage in Reciprocating Type Compressors

2- Creates Less Friction which Equals Less Wear

3- Oil Will Last up to 8 Times Longer than mineral based oils

4- No Carbon deposit build-up in Valves or Rings

5- Creates Thermal Stability & Solvency

6- No Seasonal Oil Change as with mineral oil

7- Less Impact on the Environment

8- Saves on Labor & Disposal Cost


Eight proven benefits from upgrading to quality Synthetic Air Compressor Lubricants in Rotary Vane Type Compressors:

1- Saves 8%-12% in Electrical Usage in Rotary Vane Type Compressors

2- Creates Less Friction which Equals Less Wear

3- Synthetic Oil Lasts up to 4 Times Longer than mineral based oils

4- No Carbon build-up in Vanes or Ports

5- Results in Thermal Stability & Solvency

6- No Seasonal Oil Change

7- Less Impact on the Environment

8- Save Money on Labor & Disposal Costs


Upgrading to a good quality Synthetic Compressor Oil gives you leading edge technology in lubricants:

– Profit from big savings overall, even though the initial cost a bit more

-Improve fire-resistance because of the properties of synthetic oils. Cleaner valves and less lubricant reduce the chance of fires and explosions in reciprocating air compressor systems

-Synthetic oils provide cleanliness in reciprocating air compressor crankcases that result in better heat transfer and prevention of moving parts sticking. The result can be less power usage.


There are lots of high-tech, scientific reports about synthetic lubricants you could read, but the bottom line is this: Upgrade to Synthetic Air Compressor Lubricants and save time and money!

Note: Not all synthetic compressor oils are the same. The quality and quantity of the base stocks and additives package are where the difference is. Remember the old saying – “You get what you pay for”? In this case – it’s really is true. Make sure when you upgrade from mineral oil to synthetic that you drain the mineral oil for a complete change. Don’t just “ADD” the synthetic oil to the old mineral oil.
