Commercial Hospital & Lab Ventilation in Fullerton — Fujitsu-Focused Experts

What we deliver for hospitals and labs

Healthcare and research facilities demand precise control of airflow, pressurization, and filtration. Our Fujitsu-focused solutions bring stable performance and lifecycle efficiency to critical environments in Fullerton and across Southern California.

• Design-build ventilation for ORs, ICUs, isolation rooms, pharmacies, and labs
• Negative/positive pressure rooms with monitored differential pressure
• HEPA/ULPA filtration, cleanroom zoning, and low-leak ductwork
• Fujitsu VRF + ERV/DOAS integration for energy-efficient outside air
• Humidity control and temperature stability for sensitive processes
• BMS integration, alarms, trending, and remote visibility
• Commissioning, TAB, and documentation for audits
• Planned maintenance and reliability upgrades

Engineered for compliance and safety

Our team designs and verifies systems to align with key healthcare and lab standards, including ASHRAE 170 for ventilation in healthcare facilities, CDC guidance for airborne infection isolation, USP 797/800 for sterile compounding, and California Title 24 energy requirements. We provide clear submittals, sequences of operation, and acceptance testing so stakeholders can validate performance.

Typical deliverables include:
- Airflow and pressurization schedules
- Filtration specifications and test points
- Sequences for emergency modes and setback
- Functional performance tests and TAB reports

Fujitsu-centric technology, thoughtfully integrated

We leverage Fujitsu VRF and energy recovery systems to deliver precise zone control, heat recovery between spaces, and optimized ventilation rates. When paired with ERV/DOAS and high-efficiency filtration, your facility gains robust environmental control with lower operating costs. Our engineers right-size fans and coils, tune control sequences, and verify balancing to ensure stable pressure regimes even under variable load.

Our process

• Assessment: Site walk, risk review, and data collection
• Engineering: Load calculations, zoning, and control strategies
• Integration: Fujitsu VRF with ERV/DOAS, BMS, alarms, and monitoring
• Execution: Clean installation, infection-control work practices, and changeover planning
• Commissioning: Point-to-point checks, TAB, and functional testing
• Support: Training, maintenance, and continuous optimization

Use cases we handle

- Airborne Infection Isolation (AII) rooms with continuous monitoring
- Protective Environment (PE) rooms with HEPA filtration
- Cleanrooms for life sciences and med device (ISO 5–8)
- Pharmacy compounding (USP 797/800) and lab exhaust controls
- OR suites with pressure cascades and setback modes
