Nice little unit for your birdroom available at :
Fresh air is essential in your Birdroom
When building your birdroom you must give careful consideration to how to replace the air inside you birdroom on a regular basis. Feather dust soon starts to land on all the surfaces and if inhaled can cause health problems for you or your birds. Air flow can be achieve in a number of ways, air vents, netted windows, extractor fan etc but we must be careful not to introduce drafts so careful planning is needed.
On the EBF forum there has been a number of articles written on how to achieve good air circulation for myself l have two 120mm fans one situated high on one wall blowing air in. The air is drawn in from my covered walkway while on another wall a fan draws the air out of the birdroom and is situated at a low level, the fans are on a timer and activate a number of times a day. The lower fan outlet blows into the boundary fence and on the routine inspection it was very noticeable how must dust is being expelled.
Also the hatchway to the outside flight is always open so there is some air flowing in when the fans are not working, again there is a netted opening a another wall to encourage air flow. Finally a old Air Vac system is situated on the ceiling in the centre of the birdroom which is manually operated but will soon be on a timer. The micron filters have been replace due to the age of the unit but the feather dust and other particulates are collected very efficiently judging by the amount of dust comes from the unit when its cleaned.
A vacuum cleaner is used weekly and l tend to use a weakened disinfectant mixture sprayed on the outside of the nestboxes to keep the any dust down and secondly to keep the humidity inside the nestbox correct having the wrong humidity can lead to poor hatching percentages.
Air Vacuum units are available from a number of suppliers throughout the UK and vary in price a couple of images and links to the websites are on the left hand side of this page.
It saddens me to find out that Allan Fairgrieve of Cage & Avian Solutions pasted away yesterday

I had just purchased one of Cage & Avian Solutions filter systems.
