Gram Clean Air welding filters are high efficiency filtration systems that meet the stringent W3 class standard. This ensures that the filters used not only remove welding fumes efficiently, but are also reliable and safe in the most demanding industrial environments. The filters are suitable for both manual and robotic welding and can handle airflows ranging from 500 m³/h to 35 000 m³/h.
W3 is the highest classification for welding filters according to EN ISO 15012-1. This ensures that the filter removes at least 99% of welding aerosols, including the finest metal oxides. W3 certified filters are mandatory for welding stainless steel, aluminium and nickel alloys.
Yes, Gram Clean Air offers filters specially designed for robotic welding, which operate in an automatic cleaning cycle. They are suitable for both single welding cells and multi-robot systems, providing stable filtration efficiency even in continuous production.
The choice depends on the size of the hall, the number of welding processes and the air flow. For smaller halls (up to 500 m²) Air Tower solutions are suitable, for larger halls (over 1000 m²) Push-Pull systems are suitable. We can help you calculate the required airflow and recommend the right solution.
The maintenance requirements for Gram Clean Air filters depend on the intensity of operation. Models with automatic cleaning usually require maintenance every 6-12 months, manual systems more often. All units are fitted with a filter fullness indicator, which signals the need for filter replacement.

An energy-optimised filter for a variety of major filtration tasks. The filter is used for filtering welding and cutting fumes, grinding dust and various exhaust air containing dust from metal, stone, plastic, etc. or various powder mixtures. At the time of delivery, the filter is complete and ready for immediate use after connection of the piping and power supply.
The FUV type spark arrestor protects the dust filters from sparks, thereby reducing the risk of fire in the central filter and the pipework. The FUV spark arrestor is equipped with a built-in water trap that fills automatically when the separator is connected to the water supply. This significantly reduces the risk of the filter not having the required water level in the water bath.
