Commercial Exhaust Fans in Los Angeles — Fujitsu‑Integrated Solutions

Healthy indoor air is our mission. For commercial properties across Greater Los Angeles, we engineer, install, and maintain exhaust systems that control heat, smoke, grease, odors, and contaminants—while preserving comfort and energy performance through proper makeup air and pressure balance.

Engineering‑Driven Design & Sizing

Our process starts with load calculations, airflow mapping, and code requirements. We size fans, hoods, ductwork, and makeup air to match your operations, then select VFD or EC motor solutions for efficient turndown. We deliver submittals and shop drawings for a clean, predictable build.

Fujitsu Integration & Controls

As factory‑trained specialists (Fujitsu — Japan), we integrate exhaust fans with Fujitsu VRF and controls to coordinate ventilation rates, interlocks, and pressure setpoints. This alignment reduces energy waste, prevents negative pressure, and improves comfort across zones—ideal for restaurants, offices, labs, and mixed‑use buildings.

Our team is also factory‑trained by Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China), ensuring robust multi‑brand compatibility where your facility needs it.

Installation, Retrofits, and Commissioning

We handle end‑to‑end execution: curb and roof work, grease duct and fire wrap coordination, electrical and BMS interlocks, hood balance, makeup air tempering, and final air balancing. We commission each system to spec, verify alarms and safeties, and document performance for turnover.

Maintenance & Rapid Repairs

Preventive maintenance keeps airflow stable and code‑compliant. We service bearings, belts, motors, drives, dampers, sensors, and filters; clean wheels and housings; and record static pressure, RPM, and amperage for trend analysis. If a fan fails, we offer fast response to restore safe operations.
