Air compressors are typically run on either electricity or natural gas. In either case, it is often suggested that fuel and utility costs can be quite hefty. In response to the rising costs of energy, many industries have begun seeking more cost effective ways to power their air compressors. Thus far, natural gas engine-driven air compressors have been the most energy efficient models available.

Natural gas engine-driven air compressors have been praised as an economical means of cutting emissions and energy costs. The combination of a gas powered engine and advanced rotary screws has transformed the air compressor industry. Engine-driven air compressors are so effective in controlling and limiting emissions that they are used in some of the most environmentally strict and safe states such as New York, California and Florida.

Very few industries exist that are not required to purchase air compressors certified by the American Society of Mechanical Engineers (ASME). Industries are either required by law to purchase one or simply understand the importance of an ASME-certified unit. The ASME performs rigorous testing for quality and safety on all devices bearing their quality assurance label. Manufacturers who wish to have their products certified must provide excellent workmanship along with necessary safety features such as an emergency air release valve; this valve relieves air pressure in case of an overload of energy to reduce the risk of an explosion.

Natural gas engine-driven air compressors have been in existence for more than 30 years. Over the years there has, not surprisingly, been great leaps made in technological advancement. One achievement, among many, in air compressor technology is the use of greater horsepower. An engine-driven air compressor that has the capabilities of using advanced horsepower can dramatically cut energy costs. More air is emitted with less strain on the device because of the increased horsepower. The lessening of the strain also helps parts stay in top-quality functioning order, therefore reducing maintenance and replacement costs.
