McGill AirFlow has added two time-saving conversion/calculation tools to website (www.mcgillairflow.com): TechTools and Leak Detective™ Test Kit Tools. TechTools provides users the ability to convert volume flow rate from CFM to L/s and L/s to CFM, and to convert rectangular duct to equivalent round. Leak Detective Test Kit Tools allow users to determine which Leak Detective Test Kits fit their needs, calculate allowable leakage based on leakage class, and calculate the maximum leakage (cfm) a kit can measure for a particular installation. TechTools is available to registered users and subscribers of the site; Leak Detective tools are available to all users.
