Meduim-Pressure Axial Smoke Extraction Fans – B AMD F300/F400
3 .2 Fan installation outside
Helios smoke extraction fans of type B AMD are suitable for use outside under normal weather conditions in installation
arrangements for horizontal or vertical air flow directions. The penetration of precipitation into the smoke extraction fan
must be prevented.
With regard to the insulation of smoke extraction fans, which are installed outside, it must be ensured that no precipi-
tation can penetrate into the insulation (e.g. weather protection cover).
In particular, the inlet and outlet opening area must be protected by mounting extension ducts (for horizontal air flow di-
rection) or e.g. an on-site weather proteciton cover (end/beginning of a pipe/duct sectiion for vertical air flow direction).
The openings in the fan casing must be protected against the penetration of precipitation by a suitable installation
position (openings on side or below). In this respect, particular attention must be paid to the casing feed-through for
the supply line between the casing terminal box and motor connection.

Two-stage and parallel units

The various requirements concerning pressure increases, conveying capacities and space requirements are frequently
fulfilled by two-stage Z or parallel P units in the area of Technical Building Equipment (TGA). The Helios range (see sales
documents) offers corresponding mounting kits for the respective construction:
Two-stage design / mounting kit MP-Z
Two fans connected in series (Fig.10)
ensure the unrivalled power density and advanta-
geous installation due to minimum space require-
ment. The two fans are arranged in sequence and
connected with extension ducts.
m Vertical mounting ring is not possible (MRV)
Scope of delivery:
- Extension ducts (2 pcs.) incl. mounting kit
(hexagon head screws, nuts, spring washers).

Bearing condition diagnostics

Type: LZD-Basic and LZD-Comfort
The Helios bearing condition diagnostics system serves to securely monitor the functionality of motor bearings in
the drive motor of the smoke extraction fan. The system optionally allows the early detection of imminent bearing
damage by constantly or occasionally monitoring the bearing conditions. The bearings are not replaced periodically,
but depending on the actual wear. In this respect, the test and maintenance plan in these Installation and Operating
Instructions must be observed. Before operation and the use of bearing condition diagnostics, the separate Installation
and Operating Instructions for the monitoring system must be observed.
Parallel unit / mounting kit MP-P
Two fans connected in parallel (Fig.11)
provide large air volumes with the corresponding
pressure rate and they meet the requirements for
garage ventilation and smoke extraction in particu-
lar. Two identical fans arranged side by side work
in the same duct sys tem.
Scope of delivery:
- Extension ducts (2 pcs.),
- Backdraught shutters (2 pcs.),
- Mounting brackets (4 pcs.)
- Mounting rails (2 pcs.)
- Mounting kits (hexagon head screws, nuts, spring
washers, washers and threaded plate).
