Air Flow Test & Airflow Validation in India

THE SERVICE

Air flow testing in Ahmedabad, with traceable instruments.

An air flow test measures how much air your HVAC system, cleanroom or clean air device actually delivers, and how that air moves through the space. It confirms that supply volumes, air changes and flow direction match the design, so contamination is diluted and carried away rather than left to settle.

An Air Flow Test is a method used to assess and measure how air moves within a system or space. Its purpose is to ensure that air is being properly distributed, exhausted, or circulated in accordance with design requirements and health or safety regulations.

Air Flow Validation is the process for monitoring and documenting that air flow systems, such as HVAC units, laminar flow cabinets, cleanrooms, and biosafety cabinets, are operating within specified parameters in order to maintain a controlled environment. This validation is vital in industries such as pharmaceuticals, biotechnology, & healthcare, where product quality and staff safety are important.

Kesar Testing Service LLP utilizes advanced airflow pattern testing instruments. Our airflow validation services ensure full compliance with regulatory standards.

What is Purpose of Air Flow Test?

To verify system performance (e.g., HVAC, exhaust fans, cleanrooms).

To ensure proper ventilation and air exchange.

To identify blockages, leaks, or inefficiencies in air ducts or filters.

To comply with regulations (e.g., OSHA, ISO standards).

WHY IT MATTERS

Why air flow testing matters
for Gujarat's industries.

Documented, repeatable testing shows your controlled environments perform as designed.

Design confirmed on site

Measured volumes and air change rates show whether the installed system performs as the HVAC design intended, not just whether the fans are running.

Problems found early

Low readings at a terminal or a reversed flow in a smoke study point to blocked filters, closed dampers or duct leaks before they affect product.

Audit-ready evidence

Each room and terminal is documented against its acceptance criterion, giving QA and inspectors a clear record of how the controlled area was qualified.

HOW WE WORK

How our Ahmedabad lab works with you.

Every engagement follows the same disciplined steps, so results are consistent and audit-ready.

01
Scope your requirement
Share your instrument list, rooms or systems and the standards you work to. We confirm parameters, ranges and acceptance criteria before anything is scheduled.
02
Plan the work
We agree dates, on-site or in-lab handling and the protocol to follow, so production and QA know exactly what will happen and when.
03
Measure with traceable standards
Qualified engineers carry out the work using calibrated reference instruments traceable to national standards, recording raw data as they go.
04
Report and certify
You receive clear certificates and reports — results, uncertainty or acceptance criteria, and traceability — ready for audits and regulatory inspections.

How are air changes per hour calculated in a cleanroom?

The total supply air volume entering a room is measured at each terminal filter, usually with a capture hood or by velocity readings across the filter face. That volume per hour is divided by the room volume. The result is compared with the air change rate specified in the HVAC design or the user requirement specification.

What is an airflow visualisation or smoke study?

A smoke study releases a visible, clean fog near critical points so the direction and behaviour of the air can be observed and video-recorded. It shows whether air sweeps away from the product and towards the returns, and highlights turbulence or dead zones. Regulators commonly expect it for aseptic areas under EU GMP Annex 1.

Which standard describes cleanroom airflow test methods?

ISO 14644-3 sets out the test methods for cleanrooms and clean zones, including airflow volume and velocity measurement and airflow direction visualisation. In pharmaceutical facilities the results are also assessed against GMP expectations such as EU GMP Annex 1, WHO guidance on HVAC systems and Schedule M, together with the site's own design specification.

Can the test be done without shutting down production?

Most measurements are taken at terminal filters, grilles and openings, so they can usually be scheduled around production with limited disruption. Smoke studies in aseptic areas are normally planned with the site QA team, because they may be required in both at-rest and operational conditions and need careful control of the fog source.
