Ratiovent
The highly efficient high-performance Air Curtain for industry
Teddington RATIOVENT is a powerful, high-performance air curtain system equipped with the patented CONVERGO® pressure chamber nozzle system. This nozzle system with a large, almost loss-free discharge angle adjustment range requires approx. 40% less energy for the same shielding performance as a lamella unit.
The powerful RATIOVENT high-performance Air Curtain is ideal for use in industrial applications, for horizontal and vertical installation with and without heating. It is extremely easy to install and requires little maintenance. Its robust design and powerful performance make it the most popular device in the industrial sector.
Thanks to the modular design of our Teddington Ratiovent, any door width can be covered easily and individually.
A highly directed air jet that can be used to shield very high and wide doors with low energy consumption.

Technical data
Sophisticated design
Find out more about the individual components of our Ratiovent Air Curtain systems.
Powerful and effective in performance, reliable and energy-saving in daily use.
High-quality powder coating, individual colours possible.
The complete CNC production of the housing components guarantees maximum accuracy of fit and consistently high quality.
The design meets the highest aesthetic standards.
The fine adjustment by means of a grid enables the air discharge angle of the CONVERGO® nozzle to be set precisely.
The discharge opening of the patented CONVERGO® nozzle extends almost the entire length of the appliance without interruption. This ensures maximum efficiency when several appliances are installed in series.
The large nozzle cheeks ensure a clean air flow.
An additional flow profile divides the air flow into a primary and secondary jet. The increased outlet velocity in the primary jet leads to an even greater penetration depth.
