Is a HAUTAU chain drive defective? There are matching Vent Systems alternatives for the common 24 V and 230 V chain drives. The table gives an overview.
Which Vent Systems drive replaces which HAUTAU drive?
| HAUTAU drive | Data (manufacturer) | Alternative from Vent Systems | Note |
|---|---|---|---|
| SKA 20 comfort drive | 24 V, approx. 200 N, for ventilation and SHEV | VS-KA 250 N, 24 V | |
| SKA 50 (e.g. SKA 50-500, -600, -700) | 24 V, stroke 500–700 mm, bottom-hung, top-hung, side-hung and roof windows, SHEV | VS-KA 600 N, 24 V | |
| EKA 20 / EKA 30 | 230 V, ventilation | VS-KA 250 N or 400 N, 230 V |

How do I find the right alternative to my HAUTAU drive?
At HAUTAU, SKA stands for 24 V and EKA for 230 V chain drives; the number indicates the size, and the second number often the stroke (e.g. SKA 50-600). Read the force and stroke from the type plate and choose the VS-KA with the same or higher force. For heavy roof windows, the VS-KA 2500 with IP66 offers additional reserves.
What to consider when replacing a drive
- Force: The new drive should have at least the force of the old drive. If in doubt, choose the next higher level.
- Stroke: Keep the stroke of the old drive. It is usually stated on the type plate.
- Voltage: Connect 24 V drives only to 24 V control units or SHEV control panels, and 230 V drives only to 230 V.
- Speed for SHEV: As a rule, SHEV windows must be fully open within 60 seconds. For long strokes, check whether the running speed is sufficient.
- Zugelassene NRWG: Bei zugelassenen natürlichen Rauch- und Wärmeabzugsgeräten (NRWG nach EN 12101-2) kann ein Antriebstausch die Zulassung aufheben. Tausch nur nach Rücksprache mit dem Fensterhersteller oder einem Sachkundigen.
- Brackets and installation dimensions: The original manufacturers' brackets do not fit 1:1. Use Vent Systems brackets and check the installation dimensions using our data sheet (downloads on the product page).
- Control: Vent Systems drives are controlled conventionally via polarity reversal (±24 V) or 230 V. Manufacturer-specific bus or programming functions of the original drive are not available. Check whether the existing control unit can handle the current consumption.
Does the replacement also work without the HAUTAU bus?
Yes. HAUTAU drives can be switched as standard via polarity reversal (24 V) or phase control (230 V) – just like Vent Systems drives. Comfort drive functions such as bus connection and app configuration are not available with a third-party drive.
