Indirect ventilation - AK and GWK
Indirect ventilation - AK and GWK
We are happy to help you with making a calculation
Get in contact with usContinuous ridge ventilation is a natural form of ventilation where windows hinge in the ridge along the entire length of the wide-span greenhouse. A drive tube with rack and pinion units that opens or closes the window runs parallel to the ridge. The drive tube is driven by a self-locking worm gearbox which is driven by a high-speed motor gearbox.
- Fewer motor gearboxes required.
- Various matching gear racks and options available.
- Gear racks protected against run-out and blow-out.
- Limited electrical installation.
- Very reliable.
