Commercial and Industrial Air Compressors

Sign up for e-mail updates on regulations for this and other products

The Energy Policy and Conservation Act, as amended, (EPCA) covers certain commercial and industrial equipment, including compressors, for which the Department of Energy (DOE) is authorized to establish energy conservation standards. DOE has determined that EPCA covers commercial and industrial air compressors and has been considering energy conservation standards and test procedures for such equipment.

Compression of a gas, such as air, is a thermodynamic process whereby the air enters a compressor machine or apparatus at one condition of pressure, volume, and temperature and exits at a condition of increased pressure and temperature with corresponding decreased volume. The pressurized air can be converted into useful work to power a wide variety of commercial and industrial equipment, such as: pneumatic manufacturing tools in an automated factory that assembles car parts; paint spraying machines; manufactured clothing; bulk packaging; oxidation for petroleum coking; cement plant baghouse purge systems; filling air cylinders; office and school building pneumatic heating, ventilating, and air-conditioning system valves; and high-power pneumatic tools such as jackhammers and some types of drills.

Recent and Ongoing Activities

DOE has pulled down the enforcement policy regarding the test procedure for air compressors and removed the policy from the DOE enforcement website as of May 2, 2022.  DOE expects regulated entities to begin transitioning in accordance with the current DOE regulations.

Current Standard

Compressors manufactured starting on January 10, 2025 and distributed in commerce, as defined by 42 U.S.C. 6311(7), must meet the energy conservation standards specified in the Code of Federal Regulations at 10 CFR 431.345.

Current Test Procedure

Manufacturers must follow the test procedure methods specified in 10 CFR 431.344 to determine that compressors that are currently manufactured or distributed into commerce are in compliance with DOE standards.

State Exemptions to Federal Pre-emption

DOE has not exempted any state from this energy conservation standard. States may petition DOE to exempt a state regulation from preemption by the Federal energy conservation standard. States may also petition DOE to withdraw such exemptions. For details, see 10 CFR part 431, subpart W.
