NOTES:

1) Single phase full load current for 208/230v shown; for 115v single phase, multiply by 2. For ampacity multiply current by 1.25. 3) The dBA is measured in free air 10 feet from the nozzle.
2) Three phase full load current for 480v shown; for 208/230v three phase, multiply by 2. For ampacity multiply current by 1.25. 4) Heat not available with 115v, single phase air curtains.
5) Commercial Models available in Electric Heat Only
