Performance characteristics of our smoke filters – from individual workstations to central smoke extraction systems
ULMATEC produces, supplies and installs smoke filters in performance sizes from 100 – 250.000 m³/h as standard systems.
The scope of delivery includes both mobile smoke filter extraction systems, e.g. as welding fume filters, and stationary filter systems with stands for wall mounting, outdoor installation or on the roof.
We develop special systems and sizes in close cooperation and according to the requirements of our customers – always individually and modularly, of course.
ULMATEC manufactures smoke filters in seven sizes from "XS to XXL" and can also combine them depending on the application.
They are expandable and, due to their modular design, can be individually adapted to all circumstances and customer requirements.

Why smoke filters are indispensable in industry & production
Welding fumes, solder particles, and thermal aerosols contain extremely fine particles, often with toxic components such as chromium, nickel, or zinc oxide. Without effective filtration, these particles enter the indoor air unhindered – with health, technical, and legal consequences.
Ensuring occupational safety and health
Smoke particles penetrate deep into the lungs, can trigger allergies, and are sometimes considered carcinogenic. A high-performance smoke filter reliably protects employees.
Ensuring production quality and machine availability
Fine smoke particles settle on surfaces, causing malfunctions in control electronics, sensors or optics – especially in automated systems.
Comply with laws and standards
Smoke filters help to comply with workplace exposure limits (WEL) according to TRGS 900 or DGUV 109-002 – while simultaneously reducing emissions in accordance with the Federal Immission Control Act (BImSchG).
ULMATEC smoke filters – modular, scalable, future-proof
Every ULMATEC smoke filter is part of a sophisticated system – configurable according to medium, process, and plant structure. Whether as a single filter module or as an integrated smoke extraction system.

- Fire protection – spark detection with shutdown and optional extinguishing
- Sound insulation & heat recovery: integrable for energy-efficient operation
Special filter technology for demanding applications
Storage filters for oily welding applications
Welding oiled or coated workpieces produces particularly contaminated fume particles that quickly saturate conventional filter media. In such cases, ULMATEC storage filters are used as replaceable filters – specifically designed for high particle and aerosol loads. They ensure reliable filtration with minimal maintenance and are easy to replace.
Precoating device as filter protection
For demanding applications, the smoke filter can be additionally equipped with a precoating device. This applies a fine protective powder (precoat) to the filter medium, preventing clogging by oils, resins, or fine dust particles. This significantly increases the filter's service life and improves its cleaning performance – ideal for difficult media or high throughput.
Flexible plant design – vertical, horizontal or split
ULMATEC extraction systems are not only powerful, but also exceptionally adaptable in their design.
Thanks to our modular system design, the individual components of the system can be precisely tailored to your spatial conditions and technical requirements.
Depending on the application, hall layout or space requirements, three setup options are available:
- Vertical: Compact vertical design – ideal for limited floor space
- Horizontal: Low-profile design extending horizontally – e.g., under mezzanine levels or in row installations
- Split: The modules are divided into two separate, adjacent units.
This flexibility allows our systems to be integrated efficiently and in a space-saving manner even in demanding environments – without compromising performance, accessibility or ease of maintenance.

Frequently asked questions about smoke filters
Finest particles in the submicron range – e.g. from welding fumes, soldering processes, thermal separation processes or chemical reactions.
If the emitted particles are respirable or toxic – e.g., CrNi welding fumes, medical residues, or ultrafine dust.
This depends on the load, filter type, and cleaning process. Automatic systems (JetPulse) significantly extend the service life.
Yes – many ULMATEC smoke filters are modular and can be connected to existing extraction systems or replace outdated systems.
Yes – especially when it comes to investments in occupational safety and emissions reduction. We can advise you on BAFA or KfW funding.
