V
– maximum air flow at minimum permitted pressure loss
max.
∆p
– the maximum total fan pressure is the maximum of the sum ∆p
t max.
∆p
– the minimum allowed static pressure (pressure loss of the connected pipeline) indicates the lowest value at which the fan must be set
s min.
choked (at nominal voltage at point 5c) to prevent overloading and protection activation
n
– fan speed measured at the operating point with the highest efficiency (5b), rounded to tens
U
– nominal supply voltage of the motor without regulation (all values in the table refer to this voltage)
P
– maximum power of the electric motor at the highest load, i.e. at flow rate V
max.
I
– maximum phase current at voltage U and the highest permitted load, i.e. at flow rate V
max.
(after connection, it is necessary to check this value and mark the measured current in the warranty card)
t
– the highest permitted temperature of the transported air during flow V
max.
controller
– prescribed voltage regulator for fan regulation
m*
– fan weight (±10%)
