What Sentry Air Systems does

Sentry Air Systems, Inc. is a privately held Houston/Cypress, Texas manufacturer founded in 1983 that designs, fabricates, and sells air filtration, fume extraction, and clean room equipment. Its portfolio is organized around modular, ductless recirculating systems spanning benchtop extractors (Table Sentry, Winged Sentry), portable floor units (Portable Floor Sentry, Python, Multi-Operator, RuggedAir), wall- and ceiling-mounted extractors, downdraft tables, ductless/stainless/walk-in/custom fume hoods, High-Efficiency Powder Containment Hoods for USP 800 compounding, portable clean rooms (ISO class), ambient and portable air cleaners, and commercial UV-C air purifiers (AirGuardian Pro, Germ Killer UVC 200/400), supported by a filter media line covering HEPA, ULPA, ASHRAE, specialty blended, and cleanable activated carbon filters.

Underlying technology centers on multi-stage mechanical and adsorptive filtration — HEPA at 99.97% capture at 0.3 microns and ULPA at 99.9995% at 0.12 microns, paired with custom-blended activated carbon for chemical and odor control — combined with UV-C germicidal irradiation at 253.7 nm protected by U.S. Patent #5,843,197, and configurable airflow, ductless recirculation, and optional positive-pressure architectures. The Walk-in Fume Hood Control Panel adds UL-listed central fan, LED, and filter pressure/runtime monitoring.

The business model is direct, quote-based hardware sales (phone and email, no disclosed dealer or distributor network) to a fragmented customer base across pharmaceutical compounding, medical/dental, industrial manufacturing, metalworking, electronics, laboratory/research, and arts/education verticals, with U.S.-only operations. Revenue mechanics combine one-time equipment sales with recurring aftermarket filter replacement orders on the installed base; payment terms are net-30 with full invoice amount due 30 days after invoice date, and the company markets through content (a 22+ page blog and Resource Center), SEO, trade shows, and community programs such as the SAS Clean Air Scholarship.
