Wall vent can fill the room with fresh air is not opening windows and not letting the dust, street noise, dust to the premises. And also eliminates the leakage of heat in the winter time through an open window or window vent and, thus, reduce the cost of additional heating of the room. You can safely leave the room, tightly closed all the windows and window vents, allowing the wall vent to perform their functions during your absence. Wall vent is installed in the outer wall of premises, cottages, office buildings, etc. above or near a window. Special designed construction of internal grille and air flow regulation provided smooth intake of air flow and its distribution that guarantees lack of draughts. Smooth mixing of warm and cold air in winter time prevents of extra humidity and provides the self-regulation of the climate in premises. Review: Good quality kit, easy to install - I was looking for something unobtrusive to install as I needed background ventilation to pass building regulations on a new room. This kit is of good quality and fits together pretty well. The opening mechanism on the internal vent is a little sticky on receipt but a quick spray with WD40 Silicon spray has it running very smoothly. It's easy to install and feels solid enough. The internal unit has a nice foam insert to prevent draughts and insects getting into the house. I was pleased with this kit and would buy one again. A number of the reviews have criticised the lack of instructions, but this is a very simple kit and a competent DIYer will be able to work it out easily. Review: Surprisingly effective solution for condensation problems. - We had a serious condensation problem in the bedroom (bad enough that I had to squeegee the window every morning and mop it up with a towel which was then dripping wet). It caused black mould on the ceiling and had become a real health hazard. We honestly thought, due to the cheap price, that this vent might, at best, slightly lessen the amount of water on the window. In fact, it has completely solved the problem, even after the extremely cold weather of the last few months. There is now almost no condensation on the window in the morning. Please note that we did also add extra roof insulation at the same time so I guess this might have helped too, although there is a line of thought that roof insulation actually makes condensation worse as the water can’t escape through the ceiling?? If this is the case then this cheap little vent is even more effective! Once the hole was drilled, installation was simple. We are so impressed, we have bought a second one for another room. ## Features - For use in 100mm, 4" dia walls where fresh air input is passively required. - Anti draught, washable filter vapour permeable membrane included. - Adjustable iris shutter to control airflow and possible cold spots. - Telescopic wall sleeve to fit walls up to 500mm thick. - Cowled external wall grille finished in UV protected white. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07772T4PS | | Best Sellers Rank | 200,005 in DIY & Tools ( See Top 100 in DIY & Tools ) 954 in Registers, Grilles & Vents | | Blade Length | 100 Millimetres | | Brand Name | Blauberg | | Colour | White | | Control Method | Touch | | Controller Type | Telescopic handle | | Customer Reviews | 4.4 4.4 out of 5 stars (122) | | Electric Fan Design | Window Fan | | Finish Type | White | | Included Components | No Cord | | Indoor Outdoor Usage | Outdoor | | Installation Type | Wall Mounted | | Is Product Cordless | No | | Item Dimensions D x W x H | 38.2D x 17.3W x 24.7H centimetres | | Item Type Name | Bathroom fan | | Item Weight | 1.02 Kilograms | | Main Power Connector Type | Type G | | Manufacturer | Blauberg | | Material | Plastic | | Model Name | WHM 100 DK | | Model Number | WHM 100 DK | | Mounting Type | Wall Mount | | Part Number | FGFGHRTS | | Power Source | Corded Electric | | Recommended Uses For Product | Air Circulation, Ventilating | | Room Type | All rooms | | Size | 100 mm | | Smart Home Compatibility | Not Smart Home Compatible | | Special Features | Adjustable Airflow Control, Washable Damp Control Filter | | Standby Power Shutoff | Efficient | | Style | Wall-mounted | | Switch Type | No Control | | Theme | Modern | | Unit Count | 1.0 count | ## Product Details - **Brand:** Blauberg - **Colour:** White - **Electric fan design:** Window Fan - **Mounting type:** Wall Mount - **Power source:** Corded Electric - **Product dimensions:** 38.2D x 17.3W x 24.7H centimetres - **Recommended uses for product:** Air Circulation, Ventilating - **Room type:** All rooms - **Special feature:** Adjustable Airflow Control, Washable Damp Control Filter - **Style:** Wall-mounted ## Images ![Condensation Damp Control Passive Wall Intake Vent Grille Kit with Filter 100mm (4 inch) Duct for Passive Fresh Air Anti Draught - Image 1](https://m.media-amazon.com/images/I/51txWaZbZxL.jpg) ## Questions & Answers **Q: What size core drill bit is required for this. Blauberg tech sheet shows telescopic duct as 103 & 98 mm for inner and outer duct pipe** A: I used a 107 core drill **Q: Can this be fitted to ceiling and vented to loft space?** A: Venting damp air into a loft space is not a good idea. Trapped damp air in a loft space could cause issues in the loft. This item appears to be designed for an external wall. Best installed pointing slightly "downhill" I understand, to the outside, so that any condensed water inside it can run downhill to the outside of the dwelling. I am not sure how this would work if installed vertically. **Q: Can i connect this to a tile vent?as have a bedroom in the loft.** A: The ducting for the unit is rigid so you would need to purchase flexible duct to get the correct angle to meet the tile vent. **Q: where is the best place on the wall to fit this vent?** A: Firstly, it should be mounted on an outside wall, around 150mm from the ceiling. If you already have a air ventilation shaft it's most practical to use this as it usually in an appropriate place and removes the requirement to core drill a new shaft. You should also check accessibility as you will need to get to the extractor from the outside to complete fitting. You will also require internally 240v power so that will also be a consideration. Once these factors have been taken into account, In our experience siting the extractor where the condensation or mould is forming is the best place to fit the vent. Hope this helps.
