Elta VL125 Inline Duct Fan Single Phase AC - 125mm/5"

The Elta Versaline VL125 is an all metal inline centrifugal fan for 125mm circular ducting, moving up to 212 m³/h in free air and rated in the Elta datasheet to 150 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 212 m³/h Speed Controllable What it is best used forToilets, shower rooms and small kitchenettes on 125mm ducting. It has a similar free air volume to the VL100 and its Elta performance table runs on to 150 Pa, where the VL100 table stops at 100 Pa. At 100 Pa the two are close (112 against 119 m³/h), so choose mainly on duct size.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.Compared with the Elta VL100 it is rated to 150 Pa instead of 100 Pa, although at 100 Pa the VL100 moves slightly more air. If you need more air or a choice of speeds, the Elta VL150 moves up to 468 m³/h with 3 speeds.Installation notes Fix the fan with the bracket set supplied. It can be mounted at any angle, but a vertical outlet needs a weatherpr
