Continuous ventilation

With a great selection of power drives, couplings and rack & pinion units, Lock is able to guarantee optimum quality right down the driveline. This has a beneficial impact on the bottom line and, in the long-term, it reduces service costs.

The strengths power, range of choice and modularity also apply to the product family of rack & pinion units, the EZD, AZD and ZSG ranges. With loads of 500 to 2500 N you can move anything from a simple polytunnel to the heavy double-glazed panels in a wide-span greenhouse and all types of roof and side ventilation systems.

If you need to get a move on, even the standard EWA drives can operate at up to 10 rpm. Things get even faster with the Speed-Logic, with up to 15 rpm, e.g. for open-roof vent systems.
