Explosion proof duct fans, type: KEX
KEX-type axial fans are designed for use in installations dealing with potentially explosive atmosphere (gas hazard) according to Polish Standard PN-EN 13463-1:2003 and directive 94/9/EC (ATEX).
As a supplied medium, it is possible to use clean air from circulatory ventilation or used air containing possibly some gas. Provided with a casing equipped on both sides with rolled flanges with connecting holes.
Standard Configuration:
- Diameter range: 315 to 800 mm
- Capacity range: 2770 to 35900 m3/h
- Available motor capacity: 0.12 to 4.0 kW
- Motors: 3-phase asynchronous, explosion-proof enclosed in reinforced casing, IP55 protection degree, temperature class T3 or T4.
- Standard operating temperature range: -20 to +40°C
Fan casing: perfectly round, made of alloy steel, flanges rolled from the casing wall, protected against corrosion by powder painting carried out with materials, which meet "ATEX" standard.
Used rotors: highly efficient with profiled blades made of aluminium - die-cast. Dynamically balanced in G6.3 class.
Sample labelling of a fan type: KEX500/1,1/1405/10/T3, where:
- KEX - explosion-proof duct fan,
- 500 - fan diameter in mm;
- 1.1 - motor power;
- 1405 - RPM,
- 10-number of rotor blades;
- T3 - temperature class of the device.
Fans are labelled: II2Gc IIBT4 or T3
KEX fan motors do not support RPM control.
Optionally: KEX type fans are equipped in motors that can support RPM control.
