Personal protection > Helmet air filter

With the Gritco helmet air filter case quality air can be accomplished according EN 12021. This in combination with a suitable compressed air after cooler and/or dryer. It can be used with almost any helmet or mask like our NOVA 2000 blasting helmet.

The first, interception, (pre) filter intercepts emulsions and solid particles up to 5 micron in diameter. A long working life combined with an excellent heat endurance and a good mechanical resistance makes this filter capable to be used in the hardest working conditions.

The second, coalescing, filter intercepts liquids and solids up to 0,1 micron. With a remaining oil content of 0,01 mg/m³ the air passing through this filter is practically 99,99% oil free.

Both filters are mounted with an automatic drain which drains the water/oil automatically as soon as the level of condensate lifts the floater. Also the filters are executed with pressure differential indicators. These show the clean state of the filter by a green area and the contaminated state by a red area. As soon as the red area is shown the filter elements should be replaced.

The third and last, activated carbon, filter works according the absorbing principle, eliminating all odors and vapors left after the first two filtering stages. This results in a remaining oil content of just 0,008 mg/m³.

The filter case is furthermore executed with a pressure regulator and
gauge to set the correct air flow. The 500 l/min. version can be used for two operators and the 1000 l/min. version comes with four connections. The overall dimensions of the strong stackable plastic case are: 300 x 183 x 400 mm.
