OVK1 Range

Vents OVK1 Series: Powerful Axial Wall Fans for Efficient Air Movement


Round exhaust fans for wall mounting, available in four nominal sizes: Ø 150 mm, Ø 200 mm, Ø 250 mm, Ø 315 mm


The OVK1 series represents a new generation of low-pressure axial fans designed for wall installation in demanding environments. Built for supply and exhaust ventilation systems, these fans deliver high airflow at low system resistance, making them ideal for commercial, office and industrial premises that require reliable, high-performance air exchange.

Versatile Use

Whether used in workshops, warehouses, production areas or large offices, OVK1 fans provide constant fresh air and effective removal of heat and fumes. They are also perfectly suited for direct air discharge, offering flexibility in both new installations and retrofit projects.


Robust Steel Construction

Each fan is housed in a powder-coated steel casing, ensuring durability, impact resistance and corrosion protection. The aluminium impeller guarantees strength and low weight, while precise balancing minimises vibration and noise. This robust build quality ensures a long service life even in continuous industrial operation.


Reliable Motor with Thermal Protection

At the core of every OVK1 fan is a single-phase external rotor asynchronous motor equipped with thermal overload protection and automatic reset. The motor uses slide bearings for quiet, low-maintenance operation. With IP44 protection, the fan is resistant to dust and splashes, ensuring safety and reliability in all operating conditions.

Adjustable Speed Control

The OVK1 series supports both stepless and stepwise speed control via thyristor or transformer controllers, allowing precise adjustment of airflow. When using multiple units, ensure that the maximum current load of the controller is not exceeded.


Easy Installation with Wall Ring

Installation is quick and straightforward thanks to the wall ring mounting system, which ensures stable positioning and vibration reduction. Electrical connection is made via the external terminal box with integrated power cable, simplifying setup and maintenance.


Energy-Efficient and Quiet Operation

With optimised aerodynamic design and robust components, the OVK1 series delivers quiet performance, low energy consumption and high reliability. It’s the perfect solution for continuous operation in professional environments requiring efficient air movement.

OVK1 axial wall fans combine power, durability and flexibility in one reliable ventilation solution. Suitable for both supply and exhaust systems, they provide consistent performance and long-term efficiency for commercial and industrial use.
