ESTA Absaugtechnik & -anlagen


Room- and hall ventilation system without pipelines for high flexibility in the work space.

The plug & play installations for the FILTOWER series are used when a local capture of fumes, dust and oil mist is not sufficient, or direct capture is impractical when working on large or complex work parts. The layered ventilation system recommended by the German employers’ liability insurance assurance enables you to save up to 70% on heating costs per year with the FILTOWER filter tower. The filter towers of the new generation feature highly efficient EC fans for controllable and thus energy-saving plant operation.

Filter towers deliver a clean environment

A clean environment, environmentally friendly or ecological are just some of the buzzwords in our everyday lives, but that is no surprise when we see the results of pollutants in our world, such as, for example, smog. Smog is severe air pollution and it is on the rise in many cities across the globe. In order to remedy the situation, giant filter towers to suck up air pollution have even been proposed which are hoped can help us move towards a smog-free atmosphere. But what can be done in the workplace to provide clean air and a safe and comfortable environment?

ESTA FILTOWER filter tower series – a recommended and proven solution

The FILTOWER filter tower series is a range of room and hall ventilation systems which are designed with a clean and safe working environment in mind. The filter tower can capture many forms of dust, smoke as well as oil mist. It is ideal for welding, soldering, grinding, polishing, machining and milling processes. The plug & play system requires no pipelines, just connection to the mains in the production hall, compressed air and that`s all. The filter towers are ideal when an existing air purifier is insufficient, or the size and form of the workpieces make direct capture impossible. It comes recommended by the German employers’ liability insurance association because it employs the layer ventilation principle. The polluted warm air is sucked up, it passes through a filtration process and then the clean air is then blown back into the hall or room at floor level to recirculate. This can result in up to a 70% saving on heating costs per year.

FILTOWER – Low-noise, easy handling and maintenance

The filter tower FILTOWER is low-noise. It can be easily moved around and positioned with the use of a forklift or crane. Its Jet-Pulse filter cleaning device cleans the filter cartridges individually and automatically during and after suction, resulting in a longer filter cartridgelifetime. It also features highly efficient EC fans for controllable and therefore energy-saving plant operation.

ECO variants for increased efficiency

The filter tower FILTOWER is also available in several variants, including Ecolight, Eco+ or Ecotemp, providing energy efficiency and optimising operating costs. Model 4.0. also has a LAN or WIFI connection so as to evaluate measurement data rapidly in digital format. If an existing air purifier is not capable of extracting contaminants during manufacturing processes and providing premium air quality, then the workforce and production output can suffer. An ESTA FILTOWER filter tower is a step in the right direction towards a smog-free environment.
