Elta VL100 Inline Duct Fan Single Phase AC - 100mm/4"

The Elta Versaline VL100 is an all metal inline centrifugal fan for 100mm circular ducting, moving up to 216 m³/h in free air and rated in the Elta datasheet to 100 Pa. It is built for low airflow, medium pressure systems and its compact casing suits ceiling void mounting.The galvanised steel casing comes with integral mounting brackets and 25mm spigots for flexible or rigid duct. The single phase motor is IP44 with Class F insulation, sealed for life bearings and a non self resetting thermal cut-out, and arrives with a flying lead and UK 3 pin plug. The motor is suitable for speed control once the supplied plug is removed and it is wired into a controller. Elta give a 12 month warranty. 1 Phase AC Motor Up to 216 m³/h Speed Controllable What it is best used forSingle toilet and shower room extract, small cleaners cupboards and short duct runs where a 100mm duct has to be taken through a ceiling void to an outside wall or roof terminal. It also works as a small booster on an existing 100mm duct.It is for indoor use only, and because of its non self resetting cut-out Elta say it must not be fed through a timer or from a circuit that is regularly switched on and off. For a light switch or timer run bathroom fan, choose a fan designed for intermittent switching instead.Why choose this over alternativesA backward curved centrifugal impeller holds its airflow against duct resistance far better than an axial in line fan of the same size, and it is non overloading and self cleaning. The all metal casing is a sturdier choice than plastic mixed flow units in plant spaces and ceiling voids.The Elta VL125 moves a similar free air volume (212 m³/h) but is rated in the Elta table to 150 Pa rather than 100 Pa, and the Elta VL150 adds 3 speeds and up to 468 m³/h.Installation notes Fix the fan with the bracket set supplied. It can be mounted at any angle, but a vertical outlet needs a weatherproof cover on the ducted outlet. Fit at least 1m of straight duct, the same diameter as th
