ATEX side channel blowers
For potentially explosive areas and flammable gases
Where methane, biogas or technical gases are conveyed, or where the environment is potentially explosive, blowers approved for this purpose are required. FPZ builds a dedicated ATEX series in categories 2G and 3GD.
The blowers work in pressure and vacuum systems and are available in the MS, TS, MD and TD designs.

Why ATEX from FPZ?
FPZ has lodged the performance data of its category 2G blowers with the notified body TÜV Italia (No. 0948). This gives you a tested machine that complies with the applicable regulations.
For category 3GD, the monoblock version MOR is available in addition to the standard version. Matching accessories and acoustic enclosures are also available in ATEX versions.

Frequently asked questions
Which category do I need?
That depends on the zone classification of your site. Zone 1 (gas) requires category 2G; for zones 2 (gas) and 22 (dust), category 3GD is sufficient. The zone classification is determined by the operator; we select the blower and accessories to match.
Are all sizes available in ATEX versions?
Not every combination of design, size and category is available. Tell us the medium, zone and operating point, and we will clarify the right version with FPZ.
Do the accessories also have to be ATEX-compliant?
Yes. Filters, valves, silencers and the acoustic enclosure must be approved for the zone. FPZ offers a dedicated range of accessories for this.
Can the same blower generate pressure and vacuum?
Yes. A side channel blower blows on the pressure side and sucks on the suction side. Whether you use it as a blower or a vacuum generator depends only on which side you connect. The achievable values differ; see the table.
