The Vent-Axia Gemini range of run and standby fans offers high performance double inlet forward curve fan motor impellers, typically suitable for high system resistance installation. In the event of failure the standby fan is operated, and visual fan failure indication (via integrated or optional remote indication light) is illuminated. The surface mounting model has a styled cover. For flush or duct mounting the power pack and back plate assembly is located within a galvanised steel casing and fitted with either a PVC cover for flush mounting or a galvanised steel cover for connection to ducts.

The Gemini range has an integrated overrun timer function fitted as standard, enabling versatile operation to comply with the Building Regulations Part F1 for internal rooms and Local Authority specification. The overrun timer can be manually adjusted between 1 and 20 minutes. (Units are factory set with the timer set to approximately 20 minutes).

All models incorporate a basic power pack which includes the motor housing, power on, fan run and fan fail neon indicator, which allows you to install the back plate at the first fix stage and plug in the power pack when the unit is ready for use. The power pack is pre-wired and incorporates a plug in arrangement for fitting to the back plate.
