Clean Room Validation

We conduct Air Velocity Measurement / tests to determine the average filter face velocity and uniformity, and / or the average room airflow velocity and uniformity within a clean room. The average airflow velocity is calculated by dividing the total of the airflow grid velocities by the number of readings taken. Following are the instruments used by us for Air Velocity Measurement.

Probe Type Anemometer:

Model No. 8384

We make use TSI'S Velocic Calc Probe type Anemometer for simultaneously measuring several ventilation parameters using a single probe with multiple sensors. The probe anemometer measures velocity, temperature, and also calculates volumetric flow rate and pressure measurement for static pressure. It also provides pilot tube readings and humidity measurements and performs dew points, wet bulb temperature, and heat flow calculations.

Rotating Vane Anemometer:

Models 8321,8322,8324

The TSI'S Velocicalc rotating Vane Anemometers used by us accurately measure air velocity and temperature. It also calculates flow rate, performs averaging, and determines minimum and maximum readings.

We Aeromech™ conduct complete HEPA/ULPA filter integrity testing services. These are offered for both the Pharmaceutical and Microelectronics industries. All filter integrity tests performed by us are executed in accordance with IES-RP-CC-001-86 & ISO 14644. We are equipped to perform DOP/PAO HEPA Filter Integrity Test with both Di–Octal Phthalate (DOP) and Poly Alpha Olefin (PAO) depending on client-facility’s specific requirements. We also offer HEPA/ULPA filter test to verify the integrity of HEPA/ULPA filters. The tests assure that client’s filters are in conformance with various standards and/or governing agency requirements. Testing and evaluating filters minimum once annually and potentiality twice annually is required for optimum performance. Proper documentation and certification is provided by us and this also helps predict potential performance issues and increases filter life.

We are Aeromech™ - a reputed name in offering clean room validation services. Our Particle Count Test provides complete airborne particle count cleanliness classification. The test is performed to determine the actual particle count level within the facility at the time of the test. The test identifies particle count on basis of As-Built, At-Rest, or Operational. The particle size(s) of interest, the room occupancy state and the room classification shall be known prior to the beginning of the tests and shall be as specified in the contract documents.

We conduct Room Pressurization Test for industrial clean rooms. As a part of the validation process, this test verifies that a pressure differential meet the specified requirements. We make use of Dwyer make Digital Manometer Model 477, for conducting the Room Pressurization Test. All tests are conducted by experienced and well trained technicians assuring highest level of test accuracy.

We offer Airflow Visualization Test as a part of the validation process. Visualization is carried out by using the portable Visible Vapor Generator and taking Video Graph. The purpose of the airflow visualization test is to show the actual airflow pattern throughout the unidirectional clean room. The test can also be used to demonstrate the effects on airflow caused by equipment. It is best to perform this test after all airflow velocity and uniformity tests and room pressurization tests have been performed. The test determining the airflow patterns within a room using various mediums which includes smoke, vapor source or streamers of thread or string. This visual monitoring service is important in:

• Clean Room laminar flow tests
• Airflow balancing
• Wet bench exhaust optimization
• Chemical process equipment ventilation tests
• Personnel safety exhausts verification
• Pressure balancing between rooms and spaces
• Leak detection in ducts

We conduct validation tests that include Temperature and Humidity Measurements / Tests. Two levels of temperature and humidity tests are used by us depending on the requirement. In the first level, general temperature and humidity uniformity are tested. The general level test is used to ensure that the clean room’s HVAC system maintains the specified levels of temperature and humidity required for occupant comfort. The second level or the comprehensive level test identified that the clean room HVAC systems needs to maintain the specified levels of temperature and humidity required for both occupant comfort and process temperature control.

The purpose of the lighting level tests is to verify that the installed light levels and uniformity meet the specified requirements. We make use of modern testing instruments for assessment of lighting lux levels and intensity.

We perform noise level test that measure the sound pressure. The measurements will vary based on the occupancy state-of-the-art clean room. The purpose may vary but the procedures of testing are identical.

Air Exchange Rate tests determine the total air volume get in to the room within a clean room. The use of TSI Accubalance Air Capture Hoods of Model No.8371, assures accurate test results. The hood measures air volume flowing through registers, diffusers and grills. Weighing just 7.5 pounds, these air capture hoods are easy to use and carry. These hoods simply hold the accubalance up to a diffuser or grill and read direct supply or exhaust airflow on the large digital display.

We conduct Containment Tests for client’s clean room facility. The test is carried to demonstrate that airborne contamination does not enter from a higher pressure area adjacent to the clean room by means of leaks in the construction materials. The test is conducted by trained and experienced technicians using modern instruments that assure accurate results.

We execute recovery tests for clients across Industries. These tests demonstrate the ability of the clean room to remove particulate by purging the area with filtered air. It also testifies if the room can change from a "dirty" to "clean" state within the specified time. The test is conducted by experienced technicians from our in-house team. Our technicians have enriching experience and provide clients with high quality service. The ultimate goal of our company is to assure complete satisfaction of clients through effective execution of services and by providing best array of clean room equipment. We ensure that client’s clean room facility is performing properly and accurately.

Increasing quality consciousness amongst clients and the requirement of compliance to regulatory bodies has made equipment calibration more important. The Magnehelic gauges play vital role in the safety and integrity of clean rooms. It is important to ensure that parameters of bio-safety cabinet air flow and clean room pressurization is monitored and controlled with accuracy. Our Magnehelic Gauge Calibration service is offered on-site using high accuracy and calibration standards. Our calibrators uphold industry leading accuracies and guide customers to maintain the most stringent process tolerances. Post completion of calibration, our technicians provide detailed Magnehelic Gauge Calibration certificates, which has information on as-found data, as-left data, instrument tolerance, instrument operating range and test point deviations.
