Cleanroom Certification in Denver, CO

Denver's metro area is home to one of the country's most established licensed cannabis cultivation and processing industries, alongside a growing base of aerospace and biotech manufacturing. GENTAB certifies cleanrooms and controlled environments across the Denver area to ISO 14644 standards, and provides cleanroom testing and air balancing for cannabis cultivation, processing, and extraction facilities where environmental control drives product consistency.

We measure airborne particle concentration where cleanliness matters, verify filtration performance, balance supply and exhaust airflow, and confirm the pressure relationships that keep sensitive and odor- or solvent-affected zones properly contained. Every engagement is documented against clear acceptance criteria, giving Denver-area operators the same defensible reporting GENTAB delivers nationwide.

Airborne Particle Classification: Particle count measurement and statistical analysis to determine and document ISO 14644-1 cleanliness classification at rest and in operation.

HEPA / ULPA Filter Integrity Testing: Aerosol challenge (PAO) scanning of installed filters and housings to detect leaks, bypass, and media damage before they compromise the space.

Air Change Rate & Recovery: Supply airflow measurement, air change rate calculation, and recovery testing to confirm the room clears contamination within its required time.

Room Pressurization Verification: Differential pressure mapping across doors and adjacencies to confirm correct cascade and protect critical spaces from cross-contamination.

Airflow Visualization & Uniformity: Smoke studies and velocity uniformity testing for unidirectional flow zones, documenting that airflow patterns sweep contaminants as designed.

Certification Documentation: A complete, audit-ready certification package referencing test methods, instrumentation, acceptance criteria, and pass/fail results per room.
