Description
ruck DHN is a roof-mounted smoke-extraction fan series. The current manufacturer pages confirm the exact article IDs and models DHN 225 D2 F4 30 (150593) and DHN 250 D2 F4 30 (150559). ruck describes a backward-curved radial impeller, horizontal discharge, a housing made from aluminium and galvanized sheet steel, an IE3 motor suitable for frequency control, an F400 rating for continuous operation at 200 °C, and an integrated service switch. Note: the current 150593 page embeds an image filename identifying DHN250; the image is therefore used only as a representative family image, not as the 225 variant image.
