FCP V ATEX GAS – installation instructions

FCP V ATEX GAS centrifugal roof fans are designed for installation on building roofs above ventilation shafts. They can be used for direct air extraction or in ducted industrial ventilation systems.

The vertical discharge design is particularly recommended for areas exposed to heavy rainfall, as it helps reduce the risk of rainwater entering the fan.

Mounting base and waterproofing

Suitable waterproofing systems must be used during installation to prevent water from penetrating the roof structure.

Particular attention must be paid to the contact between the fan base or the installed silencer and the supporting structure. The installer must ensure that the sealing is continuous, even and free from gaps.

Installation accessories

According to the manufacturer's catalogue, FCP V ATEX GAS fans can be connected to accessories with square or circular cross-sections.

  • CB – built-in mounting base
  • CCr and CCrz – protective grilles
  • PBZ – sound-attenuating mounting base
  • GRZ – square silencers
  • CCsa and CCsb – cylindrical silencers
  • CCbo – inlet bellmouth
  • CCf – flat counterflange
  • CCfc – counterflange with sleeve
  • RAZ – transition plate
  • CCda – backdraft damper
  • CCga – flexible anti-vibration connector

The manufacturer's catalogue provides five installation examples using different accessory combinations. The catalogue states that the accessories are not included in the type examination certificate.

Electrical connection and operation

Electrical connection and the selection of motor protection and control equipment must comply with the technical specifications of the selected model and the requirements applicable to equipment used in explosive atmospheres.

The speed of three-phase versions can be controlled using a frequency inverter. The motors are equipped with PTC thermistors for overheating protection.

Before installation, verify that the ATEX marking of the selected model is suitable for the intended operating environment and follow the manufacturer's installation and operating documentation.
