Commercial Exhaust Fans — Los Angeles

Full‑Scope Engineering for Complex Ventilation

Commercial exhaust fans are only as good as the engineering behind them. Our team sizes fans by actual CFM needs, static pressure, duct geometry, and filtration/hood resistance. We design for code compliance (IMC, ASHRAE 62.1, NFPA 96 for kitchen exhaust, and California Title 24), while controlling sound, vibration, and energy use with right‑sized motors, VFDs, isolation bases, and smart controls.

Whether you operate a commercial kitchen, biotech lab, cannabis facility, parking garage, or manufacturing floor, we integrate make‑up air, grease ducts, spark‑resistant wheels where required, and UL‑rated components to deliver stable airflow and safe dilution of contaminants. We also coordinate permits and inspections so your project passes the first time.

Systems and Brands We Handle

We service and install upblast, inline/centrifugal, tube axial, and mixed‑flow commercial exhaust fan systems, as well as dedicated make‑up air units and demand‑controlled ventilation. Our engineers are manufacturer‑trained at Mitsubishi Elektrik (Thailand), Fujitsu (Japan), Midea (China), Gree (China), and Hier (China). We apply this training to design dependable, high‑performance exhaust and ventilation solutions across diverse commercial facilities in Los Angeles.
