Tempering Air Blower Skid

Backward Curved Fan

We designed this custom backward-curved tempering air blower on a skid with a 75 HP IEEE 841 (Institute of Electrical and Electronics Engineers) severe duty motor.

Custom features included an inlet filter silencer, a removable sound insulation blanket for radiated noise, an opposed blade outlet damper to help control airflow, a pie-split housing for maintenance access, a Teflon shaft seal to protect against leakage, and a unitary base with a junction box mounting. This tempering air blower sizing is fairly large with a 23.2” diameter wheel.

Situated downstream, the tempering air blower helps increase the toughness of steel and aluminum by quenching (rapidly cooling) the very hot annealed material using clean, fresh air.

If you have a custom project, contact an application engineer to discuss it in more detail.
