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 published a Federal Register notice of final rule pertaining to energy efficiency standards for compressors.

  •  The effective date of this rule is March 10, 2020. Compliance with the new standards established for compressors in this final rule is required on and after January 10, 2025.

On April 17, 2019, the Department of Energy (DOE) received a petition from Atlas Copco North America, Inc. (Atlas Copco) asking DOE to allow compressor manufacturers to determine the applicable full-load and part-load package isentropic efficiency, package specific power, maximum full-flow operating pressure, full-load operating pressure, full-load actual volume flow rate, and pressure ratio at full-load operating pressure using either the DOE test procedure or the consensus industry test method. DOE has published a Federal Register notice of petition for rulemaking (NOPR) seeking comment on the petition, as well as any data or information that could be used in DOE’s determination on whether to proceed with the petition.

  • The comment period is closed.

For the latest information on the planned timing of future DOE regulatory milestones, see the current Office of Management and Budget Unified Agenda of Regulatory and Deregulatory Actions. All planned dates are preliminary and subject to change. DOE hosted public meetings on June 20, 2016, to address proposed test procedures and energy conservation standards for compressors.

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.


Helpful Links

Compliance

DOE has established regulations on certification, compliance, and enforcement in the CFR at 10 CFR Part 429.  These regulations cover statistical sampling plans, certified ratings, certification reports, record retention, and enforcement.  More information on these regulations is available here.

Waivers

For information on current test procedure waivers, see DOE’s Waivers webpage.

For information about obtaining test procedure waivers, see 10 CFR part 431, subpart V.

Exceptions

DOE's Office of Hearings and Appeals has not authorized exception relief for compressors.

For information about obtaining exception relief, see 10 CFR part 1003.

Guidance and Frequently Asked Questions

For information on further guidance and answers to Frequently Asked Questions on all covered products, see DOE’s Further Guidance database.

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.
