Helical In-Line Duct Fan ER-HP Series ER HP 40/4 T – Compact High-Pressure Duct Fan
The Helical In-Line Duct Fan ER-HP Series ER HP 40/4 T combines the high pressure capability of radial fans with the space-saving, straight-through airflow of axial fans. Specially developed for installation in circular ventilation ducts (nominal diameter ), this high-pressure fan effortlessly handles high pressure losses caused by long duct runs, filter systems, or duct branches.
Highlight of the ER-HP Series: Mixed-Flow Technology & High Pressure Stability
Thanks to the aerodynamically optimized helical impeller (mixed-flow principle), the ER-HP series generates significantly higher pressure build-up than conventional axial fans while maintaining high energy efficiency and a compact housing size.

Model Designation of the ER-HP Series Simply Explained
ER-HP stands for Elicoidali / High Performance – axial duct fans with high pressure capability for long ventilation runs. The specific model name is structured as follows:
-
1. Size (Number before the slash, e.g., 25, 30, 40):
Indicates the duct connection size (e.g., 25 = 250 mm, 30 = 300 mm). -
2. Number of Poles & Speed (Number after the slash):
Determines motor performance and sound level:- /2 (2-pole): ~2,800 RPM – Maximum pressure & highest airflow rate
- /4 (4-pole): ~1,400 RPM – Balanced performance with quiet operation
- /6 (6-pole): ~900 RPM – Very quiet continuous operation
- /8 (8-pole): ~700 RPM – Extremely quiet for low pressure requirements
-
3. Additional Options (Features & Power Supply):
- DP (Double Pressure): Two-stage design with dual motors for double the pressure on long duct runs.
- T (Trifase): 400 V three-phase current / industrial power (without "T" = 230 V single-phase AC).
- TP (Thermal Protector): Features brought-out thermal contacts for external motor protection.
