Technical notes
Product detail
Inline fans are specified when there is no room for a plant area and the fan has to live in the duct itself. The ID-315 uses a mixed-flow impeller, which sits between an axial and a centrifugal on the pressure/volume trade-off and suits the moderate resistance of a real duct run with bends in it.
Noise in occupied space
Because the fan is inside the building envelope, casing-radiated noise matters as much as in-duct noise. The casing is acoustically lined as standard. Where the fan passes through a ceiling void above a quiet room, ask for the casing-radiated figure specifically; the in-duct value is the one usually quoted and it is the wrong one for that question.
Mounting orientation
The fan can be installed horizontally or vertically. Antivibration mounts are supplied and should be used; a rigid mount into a plasterboard ceiling grid will transmit the running frequency into the room below regardless of how quiet the fan is.
Maintenance access
The motor and impeller assembly withdraws from the casing on a slide plate, so the duct connections stay in place during service. Allow the withdrawal length beside the fan when you set out the duct.
Control
EC motor option available, which gives smooth speed control down to low flow without a separate drive and reports its own running current over a 0-10 V or Modbus interface.
