centralised and decentralised air filtration units

Demand-driven solutions for all application areas

The fumes, dusts, chips and aerosols that are generated in production processes ask for efficient extraction and filtration solutions in order to protect your employees, improve manufacturing quality and ensure compliance with legal requirements. NOVUS offers a comprehensive product portfolio of welding fume filter systems, dedusting units and oil mist separators, ranging from plug & play devices to customer-specific centralised or decentralised extraction systems.

AirtowerMobile extraction of welding fumes with NOVUS

Wherever welding work is carried out, smoke and ultrafine dust particles are emitted into the atmosphere. And if the concentrations of harmful welding pollutants exceed the work place limit then employers need to react. This is where the NOVUS Airtower delivers with its impressive room air treatment technology. Unlike conventional extraction solutions and filtration systems, it requires no piping and can therefore be used flexibly.

extraction of welding fumes with the help of the layer ventilation principle
Airtower – a genius with two operating principles

Plug & Play principle – The Airtower has been specially developed for welding workstations. It can easily be set up based on the "plug & play" principle without the need for any pipes, and with its lifting points for forklift handling and crane eye bolts it can be quickly and easily positioned wherever you need it: Set up, connect power and compressed air supply, run.

Layer ventilation principle – The contaminated air is aspirated, filtered and then discharged as clean breathable air at ground level with no air drafts. And this through an extended 270-degree range. Here, the Airtower works following the layer ventilation principle, which is recommended by the German Social Accident Insurance Institution and is seen as the best form of air recirculation.

High-grade, reliable welding extraction...

During welding procedures, thermal flows are created that are exploited by the Airtower. The contaminated air is aspirated at the top of the unit, where it then passes through the upper intake duct and is directed towards the filter cartridges. Here, the air is then evenly distributed across the filter cartridges based on the screening principle.

... with an effective filter for welding fumes

More than 99.5 percent of contamination particles are removed – Once more than 99.5 % of the particles have been filtered out of the contaminated air, the purified air escapes from the upper side of the filter cartridge. A fan transports it to the air outlets at ground level, through which the air is then discharged back into the room without creating any drafts. For good measure there is a further fine particulate air filter upstream of the fan.

Overview of 3 systems in different power levels
Centralised ventilation system with 4 different power levels

The Airtower is suitable for use in halls of all orders of magnitude. Optimised for the relevant air volume flow, every model is available in four different power levels (in relation to the air volume flow). This means that we have perfect designs to suit every size of hall.

Airtower F – 5,000, 10,000, 15,000, 20,000
Airtower M – 5,000, 10,000, 15,000, 20,000
Airtower O – 3,000, 6,000, 9,000, 13,000

Welding fume extraction and more

The Airtower can be used in a range of different processing and machining processes. Matched to the requirements of emissions such as fume particulates, aerosols and gaseous air pollutants, a separate model has been developed for each of the three application areas: Airtower F for welding fumes, Airtower M for oil and emulsion mist, and Airtower O for odours.

  • IFA W3 approved design
  • Filtermats impregnated with activated carbon for odour reduction
  • For use as an RLT unit with integrated heat exchangers for heating or cooling
  • Room air quality sensor controls the performance of the unit
  • Wireless remote control
  • Programmable ON times
  • Filter cartridges with Nano-Layer

We also offer our customers the opportunity to adapt our units and service to their needs, so that they can be further improved and tailored to suit their individual requirements.

airtower special modelsLocalised extraction of welding fumes with our individual, specialised units

Two special models have been designed particularly for localised aspiration of welding fumes. The AirTower Pipe can be connected to a stationary piping system, while the DoubleCleaner with its two flexible and easily movable suction arms is predestined for combined localised extraction of welding fumes and room air purification.

Airtower Pipe

This variant is suitable for localised extraction of contaminated air from up to 16 welding workstations. Advantages include energy-efficient recirculated air mode in winter and the low cost and effort of installation. The low-noise Airtower Pipe is available in four power levels – 5,000, 10,000, 15,000 and 20,000.
