Axial ventilator impellers for forced ventilation: livestock, greenhouse, wall-mounted, square-plate and ducted air movement, matched to the duct, the grille and the static pressure of the installation.
A ventilator is the air-moving core of any forced-ventilation system, and its impeller has to be matched to the duct, the grille and the static pressure it works against. Selecting the ventilator on diameter alone leaves airflow and noise unverified, which is why the working point comes first.
UTEK-DELE supplies ventilators as part of the air cooling system range, so the impeller is matched to the housing and the motor it runs with. That matters most on replacement: keeping the original blade, hub and drive combination preserves the airflow, the pressure and the noise level the installation was designed to.
| Selection factor | Why it matters |
|---|---|
| Blade count and profile | Sets the airflow and pressure the ventilator delivers at speed |
| Impeller diameter | Determines the sweep and the duct or grille it fits |
| Hub family | Fixes the shaft interface and mounting of the impeller |
| Duty point | Keeps airflow, pressure and noise as designed |
Ventilators are quoted with the fan assembly they serve, so the impeller, housing and drive stay matched through the life of the installation.
Blade material is selected from the working temperature and from the atmosphere around the impeller:
| Material | Composition | Temperature range | Typical duty |
|---|---|---|---|
| Aluminium (ALU) | ADC12 die-cast | Up to ~130 °C | General and higher-temperature ventilation |
| Composite | Fibre-reinforced polymer | Moderate ambient | Corrosion-prone and damp atmospheres |
This series is normally specified for the following duties:
New fan assemblies for livestock, greenhouse and industrial ventilation
Wall-mounted, square-plate and ducted air exchange units
Replacement of a failed impeller in an existing ventilator
Service kits where impeller, hub and drive are renewed together
When a ventilator is being specified or replaced, the following points are confirmed before an impeller is released. They are the same checks used for OEM programs and for retrofit projects.
Duty point: airflow and static pressure required at the working speed, taken from the duct or ventilation requirement
Installation: available diameter, grille or shroud clearance, mounting pattern and the shaft interface of the existing hub
Environment: maximum air temperature, dust or gas atmosphere, and whether static discharge has to be avoided
Drive: available power, belt or direct drive, and whether the ventilator has to reverse in service
Service: impeller weight for handling during maintenance and spare-part availability across the machine fleet
Blade count, profile and material are then matched to those conditions in a fixed order: material first, then blade count, then hub family, with diameter confirmed against the housing. Working in that sequence keeps the mechanical interface stable when the duty requirement changes later in the project.
Each ventilator impeller is balanced before dispatch, and the blade count, hub family and duty point are recorded so a replacement keeps the original ventilation performance and noise level.
Blade count, blade profile, hub family and material can be customized for OEM programs, and existing ventilators can be reviewed when airflow, pressure or noise has to be improved on a running installation. Where an impeller is being replaced on its own, the existing hub and motor set is checked first: an unchanged drive only needs an impeller of the same duty rating.
