Positive Pressure Tube Systems for Livestock Housing.
What is a Positive Pressure Tube Ventilation System?
A Positive Pressure Tube Ventilation System (PPTS), often referred to as tube ventilation, is a custom-designed solution for livestock buildings such as calf sheds and dairy housing. Fresh air is pushed into a tube, which is suspended from a catenary wire and distributes air evenly through precision-cut outlets along its length.
By continuously supplying fresher air and diluting moisture, stale air, and airborne pathogens, PPTS systems help create a healthier environment and improve livestock welfare.
Why Choose a Positive Pressure Tube Ventilation System?
Comfortable, happy livestock
Animal welfare is critical. When livestock are kept in a clean, well-ventilated environment, they remain healthier, experience less stress, and achieve improved productivity.
Reduced vet bills
Positive pressure ventilation has been proven to reduce respiratory illnesses such as pneumonia, which are often caused by damp, cold, and humid air conditions.
Wisconsin-Style Designs
Built on expertise gained through specialist training in Wisconsin, each system is custom-designed for your barn to deliver a precise, tailored airflow solution for your livestock.
Improved air quality
Delivering fresh air directly into the animals’ immediate environment significantly improves air quality and delivers measurable health benefits.
Low running costs
Elta Agri HXP fans use highly efficient, robust motors suitable for speed control, offering proven reliability, long service life, and low operating costs.
Designed specifically for livestock housing
Installed along the length of the shed and positioned above animal height, the system provides a continuous and consistent supply of fresh air where it is needed most.
Over 250 Tube Systems Supplied Across the UK
We’ve designed and supplied more than 250 positive pressure tube ventilation systems within the last 2 years to farms across the UK, helping improve livestock health and reduce long-term operating costs.
Now Offering Wisconsin-Style
Tube Ventilation Designs
Members of the EG Agri team completed the Dairy Land Initiative Workshop on mature cow heat stress, to bring proven expertise from the US to UK farms.
These systems are highly regarded across the US and beyond for managing heat stress in dairy cows and are often requested here in the UK.
FAQs
Our tube systems are powered by an Elta HXP fan, which pushes fresh air into the building and through the tube. Air exits through carefully positioned outlets to ensure even distribution. Systems can also be paired with an HP58 controller, which automatically adjusts airflow based on temperature, helping optimise comfort and reduce energy consumption.
Tube systems are most commonly installed in dairy farms, including calf and cow housing, but they can also be suitable for equine facilities. We also offer alternative ventilation solutions for poultry units, grain stores, and other agricultural buildings.
Natural ventilation depends on weather conditions such as wind and temperature, which can make airflow inconsistent. During still, cold, or humid conditions, ventilation levels are often insufficient.
A Positive Pressure Tube System provides a controlled and consistent supply of fresh air regardless of external conditions. Air is evenly distributed along the building and introduced above animal height, helping reduce humidity, limit draughts, and lower the risk of respiratory illness such as pneumonia.
