When it comes to controlled environments, cleanrooms, compounding pharmacies, biosafety labs, and research facilities, performance isn’t optional. It’s essential. At Engineered Air Balance (EAB), we understand that achieving high performance in these spaces requires more than a single service. It requires the full integration of Testing and Balancing (TAB) with Critical Environment Certification (CEC).
We don’t separate these disciplines. We engineer them to work in tandem, because that’s what the industry demands and what our clients deserve.
A Higher Standard by Design
As the recognized authority in total system balancing and building commissioning, EAB has spent decades refining how airflow, pressure relationships, temperature, and filtration interact across complex systems. Our TAB services ensure these systems are properly configured and operating as designed.
But in critical environments, proper function isn’t enough, it must be verified, certified, and documented to meet strict regulatory and performance standards. That’s where our CEC expertise comes in.
Why the Two Go Hand in Hand
TAB is the foundation. Certification is the proof.
You cannot have reliable certification results if the underlying systems are imbalanced. A cleanroom with improper airflow, misaligned pressure cascades, or unverified terminal HEPA filter performance will fail to meet ANSI, ISO, USP, or NSF/ANSI 49 requirements — regardless of how often it’s tested.
Our approach is to integrate the two from day one:
- During TAB, our technicians verify and adjust supply, return, and exhaust airflows to support directional flow and pressurization requirements.
- As part of CEC, we validate that airflow patterns are maintained, HEPA filters are leak-free, containment devices perform properly, and viable/non-viable particulate counts stay within limits.
By combining both services under one roof, we eliminate gaps in communication and ensure total alignment from air handler to terminal diffuser, from fume hood to filter rack.
Certified to Certify and Balance
Our team is trained and certified to meet the most demanding industry guidelines, including:
- ASHRAE, AABC, and NEBB protocols for air and water balancing
- NSF/ANSI 49 for Biosafety Cabinets
- USP <797> and <800> for sterile compounding facilities
- ISO 14644, IEST, CETA, and FDA guidance for cleanroom classifications and testing
We work closely with facility staff and commissioning agents to ensure that every component of the system, mechanical, architectural, and operational, is aligned with both performance targets and compliance standards.
Practical Example: Compounding Pharmacy
In a sterile compounding pharmacy, TAB ensures the pressure differential between ISO 5, ISO 7, and ISO 8 spaces is achieved and sustainable. CEC then verifies that:
- The HEPA filters in the Primary Engineering Controls are intact
- Particle counts are within range
- Air change rates meet USP guidelines
- Containment strategies (such as negative pressure in hazardous drug rooms) function properly
Without this combined effort, certification would be incomplete and patient safety could be at risk.
The EAB Difference
Our client’s partner with us because we don’t take shortcuts. Every airflow we measure, every particle we count, and every report we produce reflects our commitment to getting it right, not just passing a test. We’re known for our technical integrity, field expertise, and transparent communication, and we bring that same standard to every cleanroom, lab, and compounding suite we enter.
Whether you need support designing a new facility or improving the performance of an existing one, our integrated TAB and CEC services are built to deliver long-term results.
