The SPMF is Lindinvent's combined damper and measurement flange designed for airflow control in circular ducts.

• Equipped with a motor shelf adapted for the DBA damper actuator.
• The SPMF damper blade requires low torque, enabling fast and precise regulation.
• The measuring flange is designed with dual measuring tubes to allow verification during ongoing regulation.
• The unit is engineered to provide good differential pressure, even at lower air velocities. Its construction ensures accurate airflow measurement, even at low airspeeds.
• Should be ordered in the FC-SPMF variant when used with the FCLb fume hood controller.

Dimensions

The SPMF is available in standard sizes of: 100, 125, 160, 200, 250, 315, 400, and 500 mm.
Lindinvent's rectangular damper JSPM, in combination with the rectangular measurement flange SMRD, is used for flow control in rectangular ducts.
