Additional specifications and description
Axial flow residential fan by Vents designed for home exhaust ventilation. Part of the Vents S-series, the STH modification is equipped with both a timer and humidity sensor allowing the fan to continue operating after the light in the room has been switched off. The desired humidity can be set via a control dial within the range of 60 to 90%, once the value is reached, the fan will keep operating for an additional period. The timer is set via a control dial and the range is from 2 to 30 minutes.
The durable UV-resistant ABS plastic housing has a modern, aesthetically appealing design that fits well in most interior spaces. The device is designed for silent operation and is suitable for intermittent and continuous ventilation. Please note that this version does not support fan speed control. The operating temperature range for the fan is between +1°C and +45°C.
Modern ventilation systems use many different fan designs that each have their advantages and disadvantages, making them best suited for a specific purpose. Residential fans can work as standalone devices for single-room exhaust ventilation. They can exhaust air directly to the outside via a wall opening or when connected to a ventilation shaft or ventilation duct. The Vents STH is best suited for residential/home exhaust ventilation. The fan is ideal for use in kitchens, toilets, bathrooms, laundry rooms and other utility rooms requiring periodic or constant ventilation. The fan is optimised for low to medium airflow at short distances and low air resistance in the ventilation duct. The silent operation and low power consumption make the fan unobtrusive and economical, even when operating constantly. The device is easy to use, as it can be operated via the room’s light switch. The fan does not require maintenance apart from periodic cleaning of the impeller.
Construction and installation:
The fan casing and impeller are constructed out of ABS plastic, which is durable and UV-resistant and will not change colour or become brittle even when exposed to direct sunlight. The built-in insect screen prevents insects or small debris from being sucked into the fan and damaging it. The device is designed to be mounted in a ventilation shaft, or connected to a flexible ventilation duct. The fan can be mounted to an interior wall or ceiling, when mounted to a ceiling, it is important to use a flexible duct or a bend. A continuous vertical path can allow water or debris to enter via the ventilation duct and damage the fan. Power is connected via a standard screw terminal. The desired timer and humidity sensor values should be set during installation.
Note that as this device creates vibrations during operation, it is important to periodically inspect the fan, to make sure the device is still securely mounted. The fan blades will require periodic cleaning and should be cleaned twice a year. The fan is not designed to handle smoke or other combustion products, corrosive chemicals and fuels, or other impurities that might stick to the blades and casing.
