Accurate and reliable product specification and performance data is one of several attributes that differentiates Schaefer products. Schaefer fans are tested in-house using certified and calibrated test equipment and test our most in-demand fans at the AMCA-certified BESS Lab at the University of Illinois.
Performance results obtained at BESS Lab are marked with BESS LAB and in-house performance results are marked with SCHAEFER.
Circulation fan performance is tested in accordance with ANSI/AMCA Standard 230-12. Performance tests yield a thrust measurement, measured in pounds force. ANSI/AMCA Standard 230-12 provides a formula for converting thrust to airflow rate (in cubic feet per minute) (Equation 9.6) which yields airflow rates approximately 29% lower than the formula in ANSI/AMCA Standard 230-99.
Published performance data is ANSI/AMCA Standard 230-99 unless otherwise noted.
We recommends using thrust measurements to compare the performance of different manufacturers’ circulation fans of the same diameter and to use caution when comparing airflow rates.
