VAPOUR VENT Passive Dehumidifier

VAPOUR VENT Passive Dehumidifier

The VAPOUR VENT passive dehumidifier alleviates condensation and mould by allowing water vapour to pass to the outside whilst restricting draughts and thereby minimising heat loss.
It is ideal for use in bedrooms or living spaces and in particularly cold areas and is most effective when used in conjunction with our Dryvent K kitchen fan or Dryvent B bathroom fan solutions.
Essentially the VAPOUR VENT compliments a ventilation system by creating a vent point for the moist air (high vapour pressure to low vapour pressure) and by enabling replacement air to enter the property and replenish the extracted air throughout the building.
It is designed to be fitted through an exterior wall and requires a 125mm or 150mm circular aperture.
BluRay 150 & 100 Auto Continuous Kitchen, Bathroom and Utility Fan

BluRay 150 & 100 Auto Continuous Kitchen, Bathroom and Utility Fan

The Sub Surface BLURAY fan is a multifunctional app controlled high performance, dehumidifying fan designed for the particularly demanding condensation control requirements of kitchen, utility or similar environments. As well as being a multifunctional fan controlled by an app, includes speed control (reversable for BLURAY 150). They are recommended for use as part of a cross-flow ventilation system with other Vapourflow units.
These units are particularly effective for damp conditions. The fan is a very neat below surface fan where nothing can be seen except for the front grille. Basic operational setting as a BLURAY unit is to to run continually, extracting at low speed to remove moisture laden air at source before it can condense. This condensation control is achieved through the inclusion of an internal Autostat unit. When the built-in Autostat detects the humidity level rising above acceptable levels the fan triggers into high speed delivering powerful performance when it is needed most. Control the Autostat unit by a remote switch or by app bluetooth control.
DRYVENT INLINE 120mm Inline Bathroom Fan

DRYVENT INLINE 120mm Inline Bathroom Fan

The DRYVENT INLINE fan is a fully automated 120mm dehumidifying fan, providing continuous low level extraction, switching to high extraction when an increase in water vapour is detected. It includes an Autostat Smart Humidity controller which automatically senses the humidity levels and can automatically change the fan speed with no user interaction needed. It also links to our VapourFlow bluetooth app, with this data from the unit can be seen and ideal dynamic or static humidity levels can be chosen for when the fan spins.
The DRYVENT INLINE unit is designed to extract air continuously on a low setting with a low running cost, it extracts air before it has the chance to condense. Especially designed for properties which suffer from damp and black mould. The background level of ventilation also improves air quality throughout the property.
The DRYVENT INLINE fan is ideally suited to isolated or hidden locations, such as; the attic, underfloor, basement, or cupboards. This unit works best as part of a cross-flow ventilation system with other Vapourflow units.
AUTOSTAT Smart Humidistat

AUTOSTAT Smart Humidistat

The Autostat IV is an intelligent, microprocessor driven humidity controller, which unlike conventional humidistats is based on a determination of absolute humidity, not relative humidity. The important difference between the two is that absolute humidity is not affected by the temperature of the surrounding environment, making the Autostat perfectly suited to environments with widely fluctuating air moisture content such as kitchens, laundry rooms, shower & bathrooms whilst not being affected by the ambient background humidity.
By way of example, cooking and tumble dryers produce copious amounts of water vapour, however a local RH% controller would register only a slight increase in RH% due to a simultaneous increase in temperature causing the air to hold more moisture (See graph below). Increased ventilation would therefore not be triggered. The Autostat would however identify a change in the moisture content of the air and react accordingly.
WAD INLINE − Warm Air Dehumidifier Fan for Attic / Whole House

WAD INLINE − Warm Air Dehumidifier Fan for Attic / Whole House

The WAD INLINE unit ensures a supply air and extract air system that will intake & extract.
The dual box fan provides for multiple ventilation options from mounted positions in the: attic, utility cupboard, bathroom, kitchen (not directly above cooker), underfloor or basement locations. Each providing a unique ventilation system meeting with building regulation requirements and most significantly a superb way of minimising air flow noise, introducing fresh pre-warmed air, when the temperature is below 14°C, and maximising condensation control.
The WAD INLINE FAN is a fully automated fan, with dual actions of both intake and extraction of air, with the benefit of warming the fresh external air when it is drawn into the building, or filtered air from the attic space. The unit is completely automatic and operating for your maximum benefit and air condition with internal humidity control, external air temperature sensor, light switch or remote timed overrun. This unit works best when used as part of a cross-flow ventilation system with other Vapourflow units.
WAD 150K − Warm Air Dehumidifier Kitchen Fan

WAD 150K − Warm Air Dehumidifier Kitchen Fan

The Warm Fresh Air Dehumidifier for kitchens is an automated kitchen fan, with dual actions of both intake and extraction of air, with the benefit of warming the fresh external air as it is drawn into the building, when the temperature is below 14°C. This unique feature is available using a single vent to the outside, that will fit onto an existing 150mm kitchen fan vent.
The WAD unit operates for your maximum benefit and air condition with internal humidity control, an external temperature sensor, light or switch extract, and app bluetooth control. This unit includes filters which helps keep out various pollutants, which should be changed yearly.
The warmed dehumidified air provides a simple and effective solution to keeping your home dry, the mild warming of the air provides for a refreshing method of keeping your home dryer by displacing wet air with dry air. This unit works best when used as part of a cross-flow ventilation system with other Vapourflow units.

DRYVENT 150 Kitchen Extractor Fan

The DRYVENT 100 & 150 fans are a multifunctional auto controlled high specification, dehumidifying fan designed for the particularly demanding condensation control requirements of kitchen, utility, or similar environments. As well as a multifunctional fan operated by an app if required, this includes speed control on both trickle and high level extract. This fan works best when used as part of a cross-flow ventilation system with other Vapourflow units.
These units are effective for damp conditions, the basic operational setting runs continually, extracting at low speed to remove moisture laden air at source before it can condense. This condensation control is achieved through the inclusion of an internal, automatic Autostat unit. When the built-in Autostat detects the humidity level rising above acceptable levels the fan triggers into high speed delivering powerful performance when it is needed most. Control the Autostat unit by a remote switch or via the bluetooth app.
