The FAAC 844 R 3 PH electro-mechanical gearmotor (ref. KTI02006002844P) is engineered to automate heavy industrial and commercial sliding gates. Operating on a 400 Vac (+6% -10%, 50/60 Hz) three-phase industrial power supply, this drive unit provides the mechanical strength, thermal endurance, and duty rating required for continuous vehicle transit portals, secure manufacturing zones, and freight corridors.
Heavy Industrial Manufacturing and Production Plants
Heavy production facilities utilize massive steel structural gates to secure wide perimeter entrances against unauthorized vehicle entry. The FAAC 844 R 3 PH handles solid-leaf sliding structures weighing up to 2,200 kg when configured with a Z12 drive pinion. Internal mechanical transmission is driven by a 950 W three-phase electric motor (2.5 A absorbed current) operating through a 1:30 reduction ratio at 1,400 rpm motor shaft speed.
Because the internal screw assembly is strictly non-reversing, the gate locks mechanically against forced back-driving upon full closure, eliminating the need to specify or wire secondary electric locks. In continuous 24/7 operating environments, the housing’s pressure-cast aluminium construction with protective cataphoresis treatment and IP 44 ingress protection withstands ambient plant temperatures ranging from -20°C to +55°C.
High-Frequency Logistics Depots and Freight Hubs
Distribution centers, bonded warehouses, and multi-modal transport terminals demand automated gate hardware capable of supporting relentless entry cycles without thermal breakdown. The FAAC 844 R 3 PH provides an intensive 70% use frequency rating, supporting up to 70 duty cycles per hour.
Continuous operation at high cycle frequencies is sustained by full oil-bath lubrication utilizing FAAC OIL XD 220 fluid. All internal gears, bearings, and the mechanical twin-disk anti-crushing clutch remain submersed, eliminating localized frictional heat and component galling during rush-hour transport traffic. Drive force can be field-calibrated between 0 and 62 Nm via a hexagonal key directly on the oil-bath clutch to protect vehicles and cargo.
Application Configuration: Z12 vs. Z16 Drive Pinions
Engineers and gate fabricators configure the FAAC 844 R 3 PH across two distinct duty profiles depending on total gate mass and required transit velocity:
| Configuration Parameter | Z12 Pinion Setup | Z16 Pinion Setup |
|---|---|---|
| Maximum Supported Leaf Weight | 2,200 kg | 1,600 kg |
| Gate Transit Speed | 7.2 m/min | 9.5 m/min |
| Target Applications | Heavy structural steel portals, industrial blast/security gates | Commercial fleet access, medium-weight high-traffic perimeter fences |
| Torque Control | 0 to 62 Nm adjustable | 0 to 62 Nm adjustable |
Critical Infrastructure and Perimeter Control Checkpoints
Commercial utilities, data centers, and corporate perimeters integrate the FAAC 844 R 3 PH alongside the dedicated external FAAC 844 T microprocessor control board. The 844 T board delivers electronic motor braking to arrest heavy gate inertia smoothly at inductive limit switch target plates, avoiding mechanical slamming on end-stops.
Perimeter automation networks can route 24 Vdc (500 mA maximum) accessory power from the 844 T board to support peripheral detection hardware such as FOTOSWITCH safety photocells, CN 60 E safety edges, T10 key selector switches, and PLUS 1 433 radio receivers. During power disruptions, access is maintained via an integrated lever-operated manual release secured with a coded industrial key.
