Air handler units are UL Listed up to 0.5 in.wc external static pressure, including air filter, set coil, and largest
kW size heater, unless otherwise noted.
• Flow rate(CFM) is decreased by 3% per 0.1in.wc from 0.8 in.wc to 1.0 in.wc
• If flow rate(CFM) is increased by 400CFM/ton from 1.5RT to 2.5RT of capacity, the ESP value should be
increased by 4.
• If flow rate(CFM) is increased by 400CFM/ton from 3.0RT to 4.5RT of capacity, the ESP value should be
increased by 5.
• in.wc = inch Water Column, inAq
• Factory Default: High Static Pressure,
High static pressure is 0.5 in.wc,
Low static pressure is 0.3 in.wc
If you set ESP incorrectly, the air conditioner may cause cooling & heating capacity down or malfunction.
