Our axial and/or centrifugal fans for multiple applications are subject to building regulations. Consultation available by following the links below:
Some practical advice from installation examples and mistakes to avoid:
The fan may or may not be connected depending on the installation network. Always use a safety guard to avoid intrusions.
|Inlet or outlet obstructions:
Leave a minimum distance of 1x the diameter of the fan to avoid affecting its operation.
|Inlet and outlet bend:
The connection from a duct to the inlet must be straight.
A bend connected directly to the inlet or outlet will affect the fan’s performance.
|Connection of the flexible flanges:
It is recommended that a rigid flange is inserted upstream and downstream of the fan before the flexible flanges are connected to avoid turbulence on the periphery.
Fans not connected to the outlet may be fitted with a diffuser cone to convert dynamic losses into static regain thanks to gradual diffusion of the air speeds.
|Air stagnation zone:
Air stagnation zones are to be avoided to improve scavenging. In some cases, carry out a fluid simulation study to optimize its installation.
Leave a space between the fan and the silencer to improve air circulation and avoid turbulence that would reduce performance.
Do not attach the fan directly to the vibration-sensitive structure or platform.
Use anti-vibration mounts and flexible flanges to isolate the unit and avoid wave propagation.
|Radial suction and discharge:
In a linear network, this type of fan must be avoided.
It is preferable to opt for an in-line fan or plenum box to optimize the circuit.
The use of round-square symmetrical transition parts is preferred.
Asymmetric parts degrade the fan’s suction or discharge conditions.
