Types of Oil-Free Air Compressors

Some of the most popular models of oil-free air compressors include:

  • Reciprocating air compressors: These compressors use positive displacement to generate air pressure from pistons. The primary benefit of a reciprocating compressor is that it can dissipate the heat generated by compression. These compressors typically have a lower output than other models, but they can still achieve relatively high air pressures.
  • Rotary screw air compressors: Rotary screw air compressors use positive displacement to create pressure like reciprocating compressors. However, the primary difference is that rotary screw compressors use a running system of interlocking screws instead of pistons. These models utilize carbon ring seals to prevent oil from entering the air stream inside the unit.
  • Scroll compressors: Scroll compressors feature a system that includes a stationary and a mobile spiral working together to bring air into the chamber for compression. Air compresses within the loop when the system decreases its volume. In the final phase, the air moves to the center of the compressor for cooling.

Scroll compressors come in oil-free designs as well as models that require lubricant.

Advantages and Benefits of Using Air Compressors Without Oil

Oil-free air compressors offer multiple advantages over oil-injected models, including:

  • Improved air quality: Oil-free models provide the best air quality possible, meaning there’s no risk of product contamination or equipment damage due to oil.
  • Energy savings: Oil-free compressors reduce energy usage and minimize leaks, which can help cut costs. Some models also come with controls to regulate airflow, providing additional savings.
  • Environmental impact: Oil-free models do not produce harmful or hazardous byproducts, making them much friendlier to the environment than oil-injected compressors.
  • Added versatility: Because of their smaller size and lighter weight, oil-free models are more portable, allowing for ease of use in tight spaces and various orientations.
