Three critical considerations when designing a compressor room for it to work correctly

Compressor rooms are essential facilities in many industrial and manufacturing settings. These rooms house the equipment that generates compressed air. Industrial premises use compressed air for various purposes, from powering pneumatic tools to operating production lines.

However, designing a compressor room requires several critical considerations to ensure efficient and safe operation. In this blog post, we will explore three of these considerations.

Compressor Room Ventilation and Air Quality

One of the most important considerations when designing a compressor room is proper ventilation and air quality.

Compressors generate significant heat, which can be hazardous if not adequately controlled. Therefore, the compressor room must have adequate ventilation to remove the heat generated by the equipment and prevent the room from overheating.

In addition, proper ventilation can help to maintain a healthy and safe working environment for personnel.

The compressor room should have a dedicated exhaust system separate from the building's general ventilation system. This exhaust system should be capable of removing hot air and fumes from the compressor room and replacing it with fresh, cool air.

In addition to ventilation, air quality is also a critical consideration when designing a compressor room. The compressed air produced by the equipment must be free from oil, water, and other contaminants that could damage the equipment or process/production parameters. In addition, a high-quality air filtration system is necessary to ensure the compressed air is clean and dry.

How to size ventilation?

A rational design is the performance-based design of fire safety and prevention mechanisms and strategies in a building to provide the same or better fire safety levels of the National Building Regulations, where the prescriptive requirements cannot be applied.

Consider undertaking the following rational design steps:

  • Determine the building heat load by summing the heat from the equipment and ambient conditions.

  • Obtain the equipment's operating conditions from the Original Equipment Manufacturer (OEM) datasheet or specification.

  • Use the OEM specification to size the ventilation system that will provide the air changes per hour to ensure the room operates within range.

The exhaust system design should comply with local and national codes and standards. You can consider South African standards such as SANS 10400, SANS 10142, SANS 54511, and SANS 60335, among others.

Compressor Room Sizing and Layout

The size and layout of the compressor room are also critical considerations when designing the facility. The room must be large enough to accommodate the compressor equipment and any associated piping and ductwork. However, it is also essential to avoid oversizing the room, which can increase energy consumption and operating costs.

The layout of the compressor room is also essential to ensure the safe and efficient operation of the equipment. It is good practice to arrange compressors, receivers, and other equipment for easy access and maintenance. There should be adequate space around the equipment to facilitate routine maintenance and repairs.

In addition, you need to consider a design that produces minimal noise levels. Compressors can generate significant amounts of noise, harming personnel and impacting nearby operations. Try to locate the compressor room in an area isolated from other workspaces, and it should consider having sound attenuation measures, such as noise barriers and acoustic insulation.

Compressor Room Electrical and Fire Safety

Compressor rooms also require proper electrical and fire safety measures to ensure the safe operation of the equipment and the facility. The electrical wiring and equipment used in the compressor room must comply with all applicable local and national codes and standards. All electrical equipment must be properly grounded to prevent electrical shock and other hazards.

Fire safety is also critical in compressor rooms, as the equipment can generate heat and sparks that can ignite flammable materials. The room should have a fire suppression system to quickly and effectively extinguish any possible fires. In addition, all electrical equipment and wiring should have a hazardous environment rating.


Designing a compressor room that works correctly requires careful consideration of several critical factors. Proper ventilation and air quality, proper sizing and layout, and proper electrical and fire safety measures are all essential to ensure the equipment's and facility's safe and efficient operation. By taking these considerations into account during the design process, industrial and manufacturing facilities can create compressor rooms that are reliable, safe, and efficient.
