Lab & Cleanroom HVAC

Cleanroom and laboratory HVAC is the highest measurement-density discipline in the trade. The air change rate, the room pressure relative to its neighbors, the HEPA filter integrity, the particle count per cubic foot at every certification class, the humidity band, the temperature band, and the supply-air velocity at the working face all have to be inside the spec — continuously, documented, and re-validated on the manufacturer’s schedule. There is no “close enough” in a cleanroom; there is in-spec or out-of-spec, and out-of-spec means the product gets rejected, the experiment gets contaminated, or the regulator writes you up.

Constant Air Balancing and Services brings 28 years of air-balance discipline to specialty cleanroom and laboratory environments across Las Vegas. We commission and maintain HVAC systems for medical and dental clean rooms, USP 797/800 compounding pharmacies, R&D laboratories, light-industrial cleanrooms, semiconductor and electronics work spaces, and ASHRAE Standard 170 compliant healthcare suites. Our air-balancing background uniquely qualifies us — measurement is the entire game in cleanroom commissioning, and most general HVAC contractors cannot pass the validation hurdle that cleanroom owners require.

Our scope covers initial commissioning, periodic re-certification, single-pass and recirculating system service, HEPA filter integrity testing, particle counting at ISO Class 5 through 8 work spaces, room pressure-cascade balancing (where positive-pressure clean spaces have to be defended against negative-pressure adjacent spaces, with measurement at every door), humidity and temperature mapping across the work area, and the documentation packages quality assurance and regulatory bodies require for ongoing certification.

We work with facility engineers, QA managers, lab directors, and the validation engineers contracted to the regulated environment. The deliverable is always documentation — particle count plots, pressure cascade diagrams, HEPA leak-test traverses, supply-velocity maps, and the certified TAB report that sits in the validation binder. Commercial air balancing is one input; in cleanroom work, the whole system is balance-driven.
