Twin City Fan Companies, Ltd.'s (TCF) airflow, acoustics, safety, and reliability testing facility is used to conduct numerous types of tests for quality assurance, research and development, product certification (AMCA license), and product safety (UL listing). It is maintained as an AMCA Accredited Laboratory* for air performance testing (per AMCA Standard 210), inlet and outlet sound testing (per AMCA Standard 300), and is a member of Underwriters Laboratories’ (UL) Client Test Data Program (CTDP). The laboratory regularly tests Axial Fans, Mixed Flow Fans, Jet Fans, Power Roof Ventilators, and Centrifugal Fans and Blowers.

In 1993, the laboratory was expanded to include a semi-reverberant room, qualified per AMCA Standard 300, and moved away from downtown noise sources to its present suburban site next to low-traffic parkland.

Our custom-designed data acquisition systems display results in real time and eliminate human error and bias. This allows for rapid, accurate testing. As required for AMCA laboratory accreditation, TCF results are periodically compared with tests of the same fan’s performance in the AMCA laboratory to verify the accuracy of results. Similarly for UL’s CTDP, all UL test standards that the TCF laboratory is listed for are witnessed annually by UL auditors to assure test procedures are maintained to UL requirements.

Engineers and Qualified Laboratory Technicians staff the laboratory. TCF is continuously upgrading its testing capabilities and equipment. Recent improvements include jet fan testing capabilities per AMCA proposed 250 draft and an additional high-pressure test chamber capable of testing up to 80 in.-w.g. The new high-pressure chamber uses a state-of-the-art National Instruments data acquisition system using a PXI 1010 PC Chassis that ties in all of the transducers and data acquisition cards required for performance testing. This new system meets or exceeds all AMCA/ASHRAE/ANSI requirements.
