Frequently Asked Questions

The FAAC C851 is a heavy-duty 230V sliding gate motor built for large residential and demanding commercial applications. It is engineered to handle substantial gate weights and high-frequency daily operation, making it suitable for busy driveways, commercial premises, industrial entry points, and gated communities.

The FAAC C851 is rated for heavy sliding gate panels, significantly exceeding the capacity of standard residential motors. It is one of FAAC's more powerful single-phase offerings, designed for gates that are too large or too heavy for lighter-duty models in the range. We can confirm exact weight specifications and advise whether the C851 is the right match for your gate.

Yes. The C851 is built with a high duty cycle, meaning it can sustain a large number of open and close operations per day without overheating or performance loss. This makes it well suited for commercial sites such as warehouses, car parks, logistics facilities, and gated industrial compounds.

The FAAC C851 supports integration with a full range of safety devices, including photocells, safety edges, inductive loop detectors, and warning lights. When connected to a compatible FAAC control board, it delivers obstacle detection, auto-reverse functionality, and programmable travel limits — ensuring the gate operates safely around vehicles, pedestrians, and animals.

The FAAC C851 is designed to work with FAAC's advanced heavy-duty control boards, which support encoder-based precision control, safety device integration, and access control connectivity. We supply the complete system — motor, control board, safety accessories, and remote access solutions — and handle installation and commissioning to ensure everything works seamlessly from day one.
