Features and Benefits


Samika is a brand new concept in ventilation and the first ever intermittent fan to have adjustable speeds for varying installation applications. The philosophy behind the design of Samika LE100 was driven from the need for Guaranteed Installed Performance (GIP) to be achieved in line with Building Regulations. After all - you might see a fan and even hear a fan - but how do you know it's doing its job?  

Samika is unlike anything else on the market and is also designed with Greenwood SMART Technology.

  • Low energy performance using as little as 1 watt in operation
  • Stylish and discreet extractor fan ideal for today's modern décor
  • Six speed set up for window, wall and ceiling applications - assisting in the delivery of the correct performance
  • No under ventilation because it's already calibrated for the resistance of the application in which it's installed, e.g. window
  • No over ventilation becasue it's already calibrated for the resistance of the application in which it's installed, e.g. ceiling with or without ducting
  • Axial fan with ultra-efficient EC motor and low voltage options
  • Available with a range of controls including SMART timer and humidistat and SELV extra low voltage (LE100, LE100T, LE100HT, LE100SVT, LE100SVIHT)


What else should you know about Samika?

  • Six speeds assist GIP - Guaranteed Installed Performance
    Independent tests carried out on a range of intermittent extract fans confirmed that where it is installed, e.g. a window, a wall or a ceiling, does impact on performance. With some over ventilating by 57% and some under-ventilating by 65%, achieving the correct performance for a particular application is crucial to eliminate issues with noise, mould and condensation or unnecessary heat loss to homes.


  • Greenwood CommissionSMART
    We want to make GIP delivery easy and simple and Greenwood CommissionSMART technology on Samika is delivered through an easy to use, centrally mounted speed selection panel which simply shows speeds 1-6 and requires only a simple button press to select the appropriate installation.


  • High quality design and manufacture
    Samika has been designed and manufactured within ISO9001 quality principles and processes, and is backed up by a full guarantee with a minimum of two years. Since 1879, Greenwood has been supplying residential solutions for homes yet still today we have an outstanding record of fewer than 0.25% of products ever returned through a fault in manufacture!


  • Greenwood TimerSMART
    The age old saying - time is money - rings true here. With typical and standard overrun timers there is always a pre-set overrun time, e.g. 15 minutes. Why? Greenwood TimerSMART uses occupancy duration to determine the overrun time period each and every time the fan is in operation.  For example, in the bathroom for 10 minutes - overrun for 10 minutes - with a maximum of 15 minutes. Designed to save money and remove nuisance overrun noise in the middle of the night.

  • Greenwood HumidiSMART
    When it’s a hot and humid summer evening, a typical humidistat fan will boost into action; not because someone's in the shower, but because ambient humidity is high. It can’t distinguish between them because it works off a generic activation point. Greenwood HumidiSMART is a patented technology and responds only to man-made spikes in humidity caused by showering, bathing and cooking. It works with the living environment to know the normal level of humidity at any given point in time. When a rapid increase from this point is sensed (a man-made activity) it activates the boost accordingly. Designed to save unnecessary over ventilation and heat loss and, most importantly, nuisance running noise especially in the middle of the night!
