Some practical advice from installation examples and mistakes to avoid:


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.
