Calculator
Medical Air Consumption Calculator
Estimate medical air peak flow and daily consumption from connected devices, average flow, and daily use hours.
Calculator Inputs
Legend
Medical Air Consumption Calculator guidance
Peak flow = devices x flow per device. Daily volume = peak flow x use hours x 60.
Input meaning
- Devices or outlets: enter the measured, quoted, or hospital-approved value.
- Flow per device: enter the measured, quoted, or hospital-approved value in L/min.
- Use per day: enter the measured, quoted, or hospital-approved value in hours.
Result interpretation
- Use the result as a planning estimate, not as a final approval by itself.
- Record the assumptions used so Procurement, Biomedical, Facilities, Finance, and vendors can review the same basis.
Assumptions
- Compressor sizing must include diversity, redundancy, dryers, receivers, air quality, pressure drop, and standards compliance.
- Clinical equipment may have peak demands higher than average flow.
Biomedical use
- Use this calculator during RFQ preparation, technical evaluation, acceptance planning, service review, or biomedical workload planning.
How to identify the required values
Use these examples and common working ranges to choose values from gauges, labels, manuals, datasheets, RFQs, service reports, CMMS records, or hospital planning assumptions.
| Field | Example value | Common range | Tip |
|---|---|---|---|
| Devices or outlets | Example: 1. | Use simultaneous devices, not only total installed outlets. | Use simultaneous active devices. |
| Flow per device | Example: 10 L/min. | Usually 0.1 L/min or higher; use the real hospital value. | Use the actual set flow or expected average flow for the clinical scenario. |
| Use per day | Example: 8 hours. | Intermittent use often 4-12 h/day; continuous ICU/utility use is usually 24 h/day. | Use real operating hours, not department opening hours if equipment remains on. |
Common ranges are starting points for hospital planning. For final procurement, acceptance testing, electrical design, medical gas design, radiation shielding, dialysis water systems, or clinical use, replace the example values with site-specific data and vendor-confirmed figures.
Input Checklist
Confirm these values before relying on the output for procurement, PM, or service planning.
- Devices or outlets
- Flow per device
- Use hours
Safety And Engineering Notes
Use calculator outputs as planning estimates and verify critical systems with calibrated measurement or qualified engineering review.
- Compressor sizing must include diversity, redundancy, dryers, receivers, air quality, pressure drop, and standards compliance.
- Clinical equipment may have peak demands higher than average flow.
