Healthcare Engineering
Medical Gas Systems
Comprehensive design of medical gas piping systems, waste anesthetic gas disposal (WAGD), and medical vacuum systems for hospitals, surgical centers, and healthcare facilities — fully compliant with NFPA 99 and all applicable codes.
Medical Gas Distribution Systems
EBS Engineering PC designs complete medical gas distribution systems that deliver life-sustaining gases safely and reliably throughout healthcare facilities. Our designs encompass the full spectrum of medical gas piping systems, from central supply sources to point-of-use outlets, ensuring uninterrupted delivery to every patient care area.
Our medical gas piping system designs include oxygen (O₂), medical air, nitrous oxide (N₂O), nitrogen (N₂), and carbon dioxide (CO₂) distribution networks. Each system is engineered with appropriate pipe sizing, pressure regulation, zone valve assemblies, and alarm systems to maintain consistent delivery pressures and flow rates at all terminal outlets.
We design both cylinder manifold systems with automatic switchover capability and bulk liquid storage systems for larger facilities. Our manifold designs incorporate duplex configurations with reserve banks, ensuring continuous gas supply during cylinder changeouts. For facilities with higher demand, we specify bulk cryogenic storage systems with vaporizers, pressure regulators, and emergency reserve supplies.
Medical Gas System Components We Design:
Waste Anesthetic Gas Disposal (WAGD)
EBS Engineering PC designs Waste Anesthetic Gas Disposal (WAGD) systems that protect healthcare workers from chronic exposure to waste anesthetic gases in operating rooms, procedure rooms, and post-anesthesia care units. These systems are critical for maintaining safe indoor air quality and complying with OSHA exposure limits and NIOSH recommended exposure levels.
Our WAGD system designs incorporate dedicated vacuum networks that are completely separate from medical-surgical vacuum systems, as required by NFPA 99. The systems capture waste gases directly at the anesthesia machine breathing circuit interface through scavenging connections and transport them via a dedicated piping network to be safely exhausted outdoors, away from building air intakes and occupied areas.
We engineer WAGD systems with dedicated vacuum pumps sized to handle the simultaneous operation of all connected anesthetizing locations. Our designs include duplex pump configurations for redundancy, receiver tanks, pressure/vacuum switches, alarm systems, and properly routed exhaust discharge points. Each system is designed to maintain the required vacuum levels specified by anesthesia equipment manufacturers while providing adequate flow rates for effective gas scavenging.
WAGD Design Considerations:
- Dedicated vacuum source — Completely independent from medical-surgical vacuum per NFPA 99 requirements
- Proper exhaust routing — Discharge located away from air intakes, operable windows, and occupied areas
- Redundant pump configurations — Duplex systems ensure continuous operation during maintenance
- Alarm integration — Area and master alarm panels with visual and audible indicators for system monitoring
- OSHA compliance — Systems designed to maintain exposure levels below 2 ppm for halogenated agents and 25 ppm for N₂O
Medical Vacuum Systems
Our engineers design medical-surgical vacuum systems that provide reliable suction for patient care throughout hospitals, surgical centers, dental facilities, and other healthcare environments. Medical vacuum is one of the most critical utility systems in a healthcare facility, supporting surgical procedures, airway management, wound drainage, and numerous other clinical applications.
EBS Engineering PC specifies medical vacuum pump systems with duplex or triplex configurations to ensure continuous availability. Our designs include properly sized vacuum pumps, receiver tanks, bacterial filters, check valves, isolation valves, pressure switches, and comprehensive alarm systems. We carefully calculate demand based on the number and type of outlets, simultaneous usage factors, and facility-specific requirements to ensure adequate vacuum levels are maintained at all terminal points.
We design medical vacuum distribution piping networks using Type L or Type K copper tubing with brazed joints, properly sized to maintain the required vacuum levels at the most remote outlet. Our designs incorporate zone valve assemblies at strategic locations to allow isolation of individual floors or departments for maintenance without disrupting service to the rest of the facility. Each system includes area alarm panels and master alarm panels to provide continuous monitoring of system performance.

Medical Gas Outlet Stations & Headwall Systems
EBS Engineering PC designs medical gas outlet configurations for every type of clinical space, from standard patient rooms to intensive care units, operating rooms, and emergency departments. Our outlet station designs utilize Diameter Index Safety System (DISS) connections to prevent cross-connection of different gas services, ensuring patient safety at every point of use.
We coordinate with architects, interior designers, and medical equipment planners to determine the optimal number, type, and location of medical gas outlets for each room. Our designs account for headwall systems, ceiling-mounted service columns, and articulating booms in critical care and surgical environments. Each outlet configuration is tailored to the clinical workflow and equipment requirements of the specific department.
Our outlet station designs follow the color-coding standards established by CGA C-9 and NFPA 99: green for oxygen, yellow for medical air, blue for nitrous oxide, black for nitrogen, white for medical vacuum, and purple/violet for WAGD. We specify outlets from major manufacturers and coordinate with headwall and boom vendors to ensure seamless integration with the architectural design.
Typical Outlet Configurations by Room Type:
| Room Type | O₂ | Vacuum | Med Air | N₂O | WAGD |
|---|---|---|---|---|---|
| Patient Room | 1-2 | 1-2 | 1 | — | — |
| ICU / CCU | 2-3 | 3 | 2 | — | — |

Medical Air Compressor Systems
EBS Engineering PC designs medical air compressor systems that produce clean, dry, oil-free air meeting the stringent purity requirements of NFPA 99 and USP standards. Medical air is used for respiratory therapy, driving ventilators, powering surgical tools, and various other clinical applications where air quality is critical to patient safety.
Our medical air system designs include duplex or triplex oil-free compressors, air receivers, refrigerated dryers, coalescing filters, desiccant dryers, carbon monoxide monitors, dew point monitors, and comprehensive alarm systems. We carefully locate air intake points to avoid contamination from exhaust fumes, loading docks, laboratory vents, and other potential sources of airborne contaminants.
We specify medical air systems with appropriate redundancy based on the facility's risk category as defined by NFPA 99. Our designs ensure that the loss of a single compressor does not compromise the facility's ability to deliver medical air to all connected outlets at the required pressure and flow rate.
