Cased high-pressure axial fans
Robust cased axial high-pressure fans, especially designed for mining installations
with large losses of load
Fan:
• Sheet steel thick long casing
• Motor base welded to the casing
• Guidelines for high aerodynamic performance for pressure gain
• Optimum surface protection by means of high-quality steel.
• High-performance, cast aluminium impeller.
• Airflow direction from impeller to motor
• Electrical connection in outside terminal board.
Motor:
• Single-phase two-speed motors with IE-2
efficiency, except lower powers 0.75 kW.
• Class F motors with ball bearings,
IP-55 protection
• Three-phase 230/400V.-50Hz (up to 5.5CV)
and 400/690V.-50Hz. (power over 5.5CV.)
• Working temperature: -20ºC +70ºC
Finish:
• High-protection, anti-corrosion steel,
specially primed and high-quality paint for
corrosive environments.
On request:
• Standardised IP-55 motors, ATEX motors
and two speeds
• Made entirely from stainless steel.
• Hot-rolled galvanised steel construction

The specified values are determined according to free field measurements of pressure and sound levels in dB(A) at an equivalent distance of
twice the fan’s span plus the impeller’s diameter, with a minimum of 1.5 m.

EXAMPLE OF SELECTION
Characteristic curves Q = Airflow in m3/h, m3/s and cfm.
Pe= Static pressure in mm.w.c., Pa and inwg.
HTP-63-4T
Initial data
• Working point:
• Airflow: 12,500 m3/h
• Loss of load: 7.5 mm w.c.
Steps for the selection
of equipment
On the pressure graph:
• 1. Mark the working point,
defined by the airflow
(12,500 m3/h) and the loss of
load (7.5 mm w.c.).
• 2. Select the curve of the
equipment which is closest
above the working point. In our
case, a curve with a blade angle
of 22º is obtained.
Absorbed power
On the power graph:
• 3. Mark the working point,
defined by the airflow
(12,500 m3/h) and the selected
blade angle (22º).
• 4. Read the absorbed power on
the power axis on the left.
Pa= 560 W at the working point.
• 5. Look for the straight red line
which is closest to the working
point above. On the right-hand
side of the graph, the value of
the installed motor power is
obtained. In our case, this is
0.75 kW or 1 CV.
