Some practical advice from installation examples and mistakes to avoid:
EXAMPLES |
|
Safety guard:
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. |
|
Diffuser cone:
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. |
|
Bulb silencer:
Leave a space between the fan and the silencer to improve air circulation and avoid turbulence that would reduce performance. |
|
Wave propagation:
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. |
|
Transition parts:
The use of round-square symmetrical transition parts is preferred. Asymmetric parts degrade the fan’s suction or discharge conditions. |
