Studying Small Air Compressor Reviews Can Help Buyers Wanting To Find Their Best Option

By Crystal Jordan


An air compressor is an important tool used in many applications including pneumatic tools (jackhammer, needle gun, nail gun), high pressure air cleaners and filling air tanks (scuba divers, fire fighters, safety equipment). Many manufacturers make small and portable compressors. They make a large number of models, each with their own unique features. Reading small air compressor reviews can help a buyer research these items and more quickly arrive at a purchase decision that best meets his or her needs.

Selecting a compressor can be a difficult matter. For one thing, it is not a decision most consumers make often. They are often not familiar with the product and its associated mechanics or technology. Moreover, there are many manufacturers. They market many models. Each model has a host of features and benefits. In short, there is a multitude of combinations and alternatives to consider. A thorough product review prepared by a knowledgeable analyst can quickly summarize the pro and cons of each model and guide the consumer to an informed, balanced decision.

Specialist magazines provide these product reviews. Comprehensive reviews are also provided online by various websites. They review the features and capabilities of available models. They make suggestions about where to get the reviewed models for the best price. Importantly, they usually also provide useful discussions on the pros and cons of various product features.

A quick example of this last point may be helpful. In technical terms, an air compressor converts power produced by a motor or engine into kinetic energy by compressing air. Air, or any other object, has kinetic energy if it is put into motion, the word kinetic being derived from a Greek word (kinesis) meaning motion. The source of power for the device can be an electric motor, a diesel engine or a gasoline engine.

Each of these power sources (namely, electric, diesel or gasoline)may have different implications and benefits for different users. For instance, there might be important variations in product efficiency, weight, noise and emissions. A product review will identify each point of difference and systematically examine the associated advantages and disadvantages.

As a second example, it is important to note that all compressors divide into one of two types according to the method used to compress air. One type is called positive-displacement the other negative-displacement. Both types are widely available as small, portable compressors.

Positive-displacement units channel air through a one-way valve into a receiving chamber. The air is trapped in that chamber. The chamber is then compressed, compressing the air trapped within it. Negative-displacement units employ a spinning impeller to create centrifugal force. That force causes trapped air to spin and compress as a result. These alternative design modes may be a real point of difference for some users.

Reading small air compressor reviews prior to finalizing a purchase decision may be of real benefit to a consumer. It is likely to save a lot of time in gathering information on different product features, models, makers and retailers. Reviews might also alert a consumer about new product capabilities not previously available. The main objective of a review is to help a consumer pick the product that best meets his or her needs. That is no mean feat. Time spent studying a thorough and balanced product review usually saves a lot more time somewhere else in the purchase process.
