Description
HTMF has a painted galvanized steel base, an adjustable cast aluminium impeller, a guard per UNE-EN ISO 12499 and a cowl with natural air outlet. Sizes 56–125 (impeller 560–1250 mm) are made for 4, 6 and 8 poles, with two-speed 4/8 and 6/12 versions, power 0.55–15 kW, and HTMF/IE5 is fitted with an IE5 motor. THT/ROOF discharges air vertically, has an aluminium sheet non-return damper against water entering when the fan is stopped, sizes 40–125 and power of 0.55–37 kW. For THT/ROOF, two-speed motors and versions for 2 and 8 poles are made on request. Motors of both series are class H for S1 and S2, IP55, with ball bearings. Supply is 230/400 V 50 Hz up to 3 kW and 400/690 V 50 Hz above 3 kW. Air temperature is from −25 to +40 °C, and up to +50 °C in a hot climate. Both series are also suitable for daily extract ventilation.
How to choose
HTMF is taken when a cowl with natural air outlet and airflow of up to 83 660 m³/h is needed, THT/ROOF where a vertical discharge with a non-return damper and up to 131 000 m³/h is needed. For large airflows without fire resistance requirements there are the related series HTMV and HTMH, and for explosive zones HTMV/ATEX and HTMH/ATEX. If the fan has to stand in a duct, look at THT and THT/CL.
