Ex II 3 G Ex db IIB + H2 T4 Gb X / Ex II 3 G Ex h IIB + H2 T4 Gb X. For use temperatures of -20 ° C < = Ta < = + 40 ° C MAICO Ex- fans meet the safety requirements of European Directive RL 2014 / 34 / EU for equipment and protection systems in potentially explosive areas. For zone 2. Types of protection: d - pressure-resistant capsulation and c - constructive safety. High-pressure fan for industrial applications. Low noise level and high efficiency. Suitable for the promotion of corrosive and acid-containing air. For easy and direct installation on a pipe system. The engine is located outside the air stream. Housing made of high-quality, conductive plastic, antistatic. Standard alignment for case LG 270 °. Suitable for temperature ranges from -20 ° C to + 40 ° C The engine base made of epoxy coated steel sheet, for fixing the fan, is included in the delivery. Radial wheels with reverse curved polypropylene shovels. Motor: Apsychroner rotary current motor. Protection type IP55. IE3 engine. Type of operation S1 (continuous operation). Temperature class T4. Fastening for motor made of epoxy coated steel sheet. Speed control with frequency inverter. The permissible frequency range for speed control with frequency inverter is 20 Hz to 50 Hz. The temperature in the fan engine is monitored by cold conductor. The cold conductors must be connected to a discharge system (safety device in accordance with Directive RL 2014 / 34 / EU) which permanently separates the fan from the net at too high temperatures. Electric connection: connection in the terminal box on the engine. Cable connection in Ex d version included in delivery.
