Can the air compressor room and the high- and low-voltage switchgear rooms be located adjacent to each other?

Key conclusion: It is generally not recommended to apply it directly adjacent to the skin.

In industrial plant and park planning, the siting of air compressor rooms and high- and low-voltage switchgear rooms is of paramount importance. From the perspective of equipment operating characteristics and environmental requirements,It is generally not recommended to place the two directly adjacent to each other.High- and low-voltage switchgear rooms have extremely stringent requirements for dust control, moisture protection, and vibration isolation, whereas air compressor rooms generate significant vibration, noise, and heat during operation, creating an inherent conflict between their respective environmental needs.

The main risks facing proximity marketing deployments

If the air compressor room is designed adjacent to the electrical distribution room, it may pose the following potential hazards to the safe operation of electrical equipment:

• Vibration interference:During operation, air compressors generate continuous low-frequency vibrations. Prolonged vibration may cause electrical components within the distribution cabinet to loosen, leading to poor contact and potentially triggering false tripping of relay protection devices.
• Effects of Temperature, Humidity, and Oil Contamination:The air compressor room generates substantial heat, and some equipment may emit trace amounts of oil and gas. If containment is inadequate, high temperatures and oily, dusty contaminants could enter the electrical distribution room, accelerating the aging of insulating materials and shortening equipment life.
• Potential hazards of water and oil leaks:Water-cooled air compressors and aftertreatment equipment are connected to cooling water systems; in the event of pipe rupture or inadequate condensate drainage, there is a risk of water leakage. Water pipes must not pass through distribution rooms, and no potential leakage hazards are permitted.

Protective measures that must be applied when time is limited

If site constraints necessitate the adjacent placement of these two facilities, stringent physical isolation and protective measures must be implemented in both the structural design and the MEP (mechanical, electrical, and plumbing) systems.

• Structural Vibration Isolation Design:The foundation for air compressor equipment shall be separated from the building’s main structural system, with a dedicated foundation provided and equipped with specialized vibration-isolating pads or isolators to eliminate solid-borne sound and vibration transmission at the source.
• Solid wall isolation:The partition wall between the two areas must be a solid fire-resistant wall without any door or window openings, and it must provide adequate sound insulation and moisture resistance to ensure the airtightness of the distribution room.
• Pipeline avoidance strictly enforced:It is strictly prohibited for any water pipes, oil pipes, or compressed air pipes unrelated to the distribution room to pass through the top or interior of either the high‑voltage or low‑voltage switchgear rooms. The drainage and venting lines of air compressors shall be properly routed to the outdoors or to a dedicated trench.
• Independent ventilation and heat dissipation:The ventilation and air-conditioning systems for the two rooms must be completely independent to prevent hot or oil‑contaminated air from the compressor room from entering the electrical distribution room via the ventilation ductwork.

Summary and Planning Recommendations

When conducting site master planning and architectural design, high- and low-voltage switchgear rooms should be prioritized for placement in areas that are environmentally clean, free from severe vibrations, and devoid of potential water‑logging hazards. The air compressor room should, whenever possible, maintain an appropriate safety distance from the switchgear room. If adjacency is unavoidable, strict adherence to relevant building and electrical design codes is required, with comprehensive vibration isolation, waterproofing, and fire‑resistance measures implemented to ensure the absolute safety of the power supply and distribution system.
