Explosion proof axial fans AVWOSE EX-ATEX ≤11000m³/h

• AVWOSE EX-ATEX explosion-proof axial fans designed to convey vapor or gas directly outside from commercial, industrial and other premises where there is a high risk of explosion due to explosive or flammable gas
• complies with ATEX directive
• AVWOSE 2G - fans intended for operation in Z1 (1) and Z2 (2) gas explosion zones are identified by the following symbols:

• temperature class: T1 to T3 (special order T4)
• explosion group: II (Subgroups IIA and IIB)
• fans not fitted for speed control
• maximum ambient temperature 40 °C
• AVWOSE 3G / 3D - fans designed to operate in the Z2 (2) and Z22 (22) gas and dust explosion areas are identified by the following symbols:

• temperature class: T1 to T3
• maximum dust surface temperature up to 120 °C
• maximum ambient temperature 40 °C
• gas explosion group: IIA and IIB
• dust explosion group: IIIB
• fans adapted for speed control by a special frequency converter
• temperature sensors (3xPTC 155C) mounted on the fan motor should be connected to an EC certified relay to ensure proper motor protection during control
• explosion-proof fans for zone Z1 (1) with frequency converter can be ordered on request
• the reverse is available on request for all models
• fan housing made of galvanized steel, powder or antistatic coated (depending on model)

• motor side hot galvanized or powder coated, impeller side mesh available on request
• manufactured under Directive 8/37/EC - Machinery Safety, Directive 94/9/EC (ATEX) - Equipment and protective systems in potentially explosive atmospheres
• marking of zones:
• Z1 - zone in which, under normal conditions of use, a vapor or gas mixture may be formed
• Z2 - zone with low probability of explosive gas mixture, explosive mixture may only be present for a short time
• Z22 - area with low probability of formation of explosive dust mixture, ie. transient, for example, during a fault
• 1 year warranty
