Systems We Install and Service

Rooftop centrifugal upblast/downblast fans, inline and mixed‑flow fans, wall‑mounted prop fans, kitchen hood exhaust (UL 762), make‑up air units, garage exhaust with CO sensors, lab process exhaust, and custom solutions for heat, odor, smoke, and particulate control.

Code and Compliance Expertise in Anaheim

We engineer for real‑world inspections and day‑to‑day performance. Our team understands NFPA 96 for commercial cooking, IMC/CMC, California Title 24 energy standards, seismic requirements, grease duct clearances, backdraft dampers, curb adapters, fire suppression interlocks, and makeup‑air tempering. We coordinate with local inspectors so your project passes the first time—reducing downtime and change orders.

Industries We Serve

Restaurants and food halls, hospitality, manufacturing and light industrial, warehouses and distribution, retail and grocery, gyms and studios, laboratories and R&D, healthcare offices, cannabis cultivation/processing, and parking garages. Whether you need quiet, continuous ventilation or heavy‑duty grease and smoke extraction, we tailor the fan and duct system to your process and space.

Our Proven Process

1) Site assessment and airflow audit (heat/contaminant sources, air paths, and discharge location).
2) Engineering and CFM sizing (capture velocity, duct friction loss, and noise considerations).
3) Equipment selection (efficiency, static pressure, maintenance access, and life‑cycle cost).
4) Controls and make‑up air strategy (VFD/EC motor optimization, pressure balance, economizer logic).
5) Installation and seismic anchorage, curb/roof work, grease duct, and electrical.
6) Commissioning, test & balance (TAB), training for your staff, and documentation for compliance.

Energy and IAQ Upgrades That Pay Back

Unlock lower operating costs and better indoor air quality with EC motors and VFDs, demand‑controlled ventilation using CO/CO₂ or kitchen hood heat sensors, premium bearings and belts, and right‑sized make‑up air with gas or electric tempering. Smart controls prevent negative pressure, reduce odor complaints, and extend equipment life—without sacrificing capture or comfort.

Maintenance That Prevents Downtime

Our PM programs include belt inspection/tensioning, bearing lubrication, wheel cleaning and balance, motor amp checks, vibration analysis, grease containment, damper function, airflow verification, and filter/hood/duct scheduling. Routine care keeps air moving, reduces noise, and protects your warranty—so your operations stay on schedule.

Emergency Repairs and Fast Replacements

When a fan fails, heat, smoke, and odors can halt business. We offer same‑day troubleshooting, motor and capacitor swaps, belt and bearing replacements, curb and shaft repairs, and rapid change‑outs with like‑for‑like or upgraded solutions—tested, balanced, and ready for inspection.
