Commercial Hospital & Lab Ventilation in Long Beach

Engineered Ventilation for Hospitals and Labs

From negative‑pressure isolation rooms to ISO‑classified cleanrooms, our engineer‑led process ensures your Long Beach facility receives safe, efficient, and verifiably compliant ventilation. We design around ASHRAE 170, FGI Guidelines, HCAI (OSHPD) requirements in California, NFPA 99, USP 797/800, ISO 14644, and Title 24—then prove performance with testing and documentation.

Design‑Build and Retrofits

Whether you are expanding a surgical suite or modernizing a university lab, we deliver turnkey solutions that reduce risk and downtime. Our team models airflows, room pressure cascades, heat loads, and acoustics to select right‑sized equipment and duct systems that integrate cleanly with your operations.

• Daikin commercial air systems, VRV/VRF, and applied air handlers integrated to your standards
• HEPA and MERV 13+ filtration strategies for ORs, AIIRs, cleanrooms, and labs
• VAV with reheat, terminal boxes, and pressure‑independent control
• Positive/negative pressure room zoning with real‑time monitoring
• Energy recovery ventilators (ERV) to cut operating costs
• UV‑C or equivalent in‑duct disinfection strategies where appropriate
• Seismic bracing and California code compliance details

Commissioning, TAB, and Validation

We commission every project as if it were a critical environment—because it is. Our technicians execute a documented plan including TAB (testing, adjusting, balancing), room pressure verification, air change rate confirmation, filtration validation, and alarms/controls testing. You receive commissioning reports, red‑line drawings, and training for staff.

Controls and Visibility

We implement controls that keep clinicians, researchers, and facility teams informed. That includes pressure monitors with local and remote displays, trend logging, and alerts tied into your BMS over BACnet or other open protocols. Our goal: predictable, auditable performance 24/7.
