Combifab Fans from Envirox are available as Combifab F for normal dust and fumes and Combifab FZ for explosive / combustible dust. These are heavy duty centrifugal fans with 3 different fan wheel designs and 4 housing and drive configurations to meet the application requirements.
Combifab F and FZ Fans
Combifab F and Combifab FZ fans from Envirox provide up to 87% efficiency with very low energy consumption and low maintenance costs in direct-driven or belt-driven variations.
An efficient industrial fan design solution is a direct driven configuration with a Variable Speed Drive (VSD) on the fan motor instead of a belt driven configuration, which requires 2% – 5% more energy than a direct drive and VSD arrangement.
The fan performance can be modified manually through the VSD control interface and a PID Control Loop, and energy consumption can be minimised by installing autogates, ultimately contributing to economical management of resources and waste and more effective production.
Our Combifab fans have a 200 – 200 000 m³/h airflow.
3 impellers form the heart of our Combifab Fan systems:
- Clean Air Impeller – Type R
A closed bladed impeller with backward curved blades, used for transport of clean air and air with a small quantity of fine dust, such as welding smoke, oil mists or exhaust gases. It has an efficiency of up to 87%.
- Chip Impeller – Type S
A closed, partly self-cleaning bladed impeller with straight, backward oblique blades, used for transport of grinding and polishing dust, dry sawdust and shavings. The chip impeller has up to 81% efficiency.
- Transport Impeller – Type T
An open, self-cleaning bladed impeller with straight, radial blades, it has an efficiency of up to 61% and is used for transport of shavings, chips, and other materials.
