Positive Pressure Fan Cfm

Whether exhausting air or bringing fresh air into a structure the calculation produced should help to figure out the size of fan s required to accomplish the air exchanges needed.

Positive pressure fan cfm.

Fan cfm calculator this fan calculator is typically used to calculate the cfm or cubic feet per minute of air exchange that may be desired in a building. It is assumed that the higher the volumetric airflow the more effective a fan will be in ventilating a given structure.

Provide a convenient portable source of air with the firestore s selection of positive pressure fans. Selecting a fan for firefighting and rescue operations comes down to ensuring you have the right flow performance for the right mission. We manufacture a complete line of battery electric gas and water fire rescue fans backed by unmatched service and support. Because air heads from a high air pressure area toward a low pressure area the concept pulls pushes the fire and debris toward the exhaust point with it.

This is seen as one moves to the right in the table. As static pressure increases similar to having a wind blow against the fan a fan s cfm or air delivery capacity decreases. We also carry electric smoke ejectors blower exhausters confined space heater systems and more. Positive pressure ventilation fans blowers are used to push fire and debris in the air toward an exhaust point.

This makes them better than high airflow counterparts at moving air through radiators case meshes and dust filters. Many companies use cfm or m3 h claims to market their fans and many in the fire industry directly relate these claims to fan effectiveness. Amca airflow tested on battery to 12 400 cfm. For mechanically ventilated pig barns it is suggested that the cfm value be chosen at either 1 10 or 1 8 static pressure for design purposes when selecting fans.

Static pressure fans are designed to combat this with a different fin design. Positive pressure ventilation ppv blowers.
