Vent-Axia 476311 Lo-Carbon PoziDry Pro Positive Input Ventilation (PIV) with Heater

The Vent-Axia 476311 Lo-Carbon PoziDry Pro™ with Heater is an advanced Positive Input Ventilation (PIV) system designed to help prevent and control condensation, damp and mould within residential properties.

Ideal for refurbishment and social housing projects, the PoziDry Pro™ quietly introduces fresh, filtered air into the property from the loft space, helping to dilute and replace stale, moisture-laden air. Featuring an integrated 500W heater, the unit helps temper incoming air to improve occupant comfort during colder months.

Key Features

  • Positive Input Ventilation system with integrated 500W heater
  • Designed to reduce condensation, damp and mould
  • SmartSense™ technology for simple setup and intelligent control
  • Ultra-low noise operation with low running costs
  • Fully adjustable airflow between 11 l/s and 49 l/s
  • Energy-saving Lo-Carbon DC motor technology
  • Includes ceiling diffuser, flexible ducting and G4 filters
  • Optional F7 filters available for PM2.5 filtration
  • Supplied with anti-vibration joist mounting legs and hanging kit
  • 5-year manufacturer warranty
  • IPX2 rated

How the PoziDry Pro™ Works

The loft-mounted unit draws fresh air from the roof space, filters it and gently distributes it into the home through a discreet ceiling diffuser. The continuous supply of filtered air helps reduce moisture levels while improving indoor air quality.

Using SmartSense™ technology, the system automatically adjusts airflow levels based on the property size and loft temperature conditions, ensuring efficient and comfortable ventilation throughout the year.

Intelligent Comfort Control

The PoziDry Pro™ automatically adjusts performance depending on loft temperatures:

  • Trickle Mode: Quiet continuous background ventilation
  • Energy Recovery Mode: Increases airflow when excess heat is detected in the loft
  • Stand-by Mode: Stops warm loft air entering the property during hot summer conditions

The integrated heater automatically activates when required to help take the chill off incoming air.

Flexible Installation

Designed for installer convenience, the PoziDry Pro™ includes anti-vibration mounting legs suitable for joist widths between 300mm and 650mm, along with a hanging kit for alternative mounting options.

The lightweight unit features an integrated carry handle for easier loft access and installation. The supplied ceiling diffuser uses a simple four-point fixing system for fast and repeatable fitting.

Advanced Filtration

Supplied with G4 filters as standard, the unit helps capture everyday airborne particles such as dust and pollen. Optional F7 filters are available to improve indoor air quality further by filtering PM2.5 pollutants including smoke, diesel particulates and spores.

Data Logging & Smart Controls

SmartSense™ technology provides intelligent monitoring and data logging, including:

  • Operating speed history
  • Runtime monitoring
  • Heater activity tracking
  • Energy usage recording

The interface can also be locked to prevent accidental adjustment of settings.

The Dog LOVES IT!
I bought this for my ex-wife's Pitbull. He is an aggressive chewer and usually destroys any toy I buy him. But not this one! The ball is small enough and pliable that it gives when he chomps on it. He loves this ball and seems to be his favorite toy. Thank you for making a product that he likes and can't destroy!

My Golden Retriever’s favorite
We’ve owned lots of toys and balls. This specific version (in blue) has been her absolute favorite. She’s about 72lbs and chews on this thing regularly with no visible damage. We actually own about 6 of them because they have a tendency to go missing underneath furniture and in the yard. We have two of the orange colored ones but she doesn’t like those nearly as much which I assume is because the blue is easier to see in the grass. Other than that…They bounce really well and also whistle a little when you throw them hard enough. I hope they never stop making these.

doesn't whistle as loud as other chuckit balls I've seen, but a good ball.
makes some noise, but I've seen (and played with) others at the dog park that whistle much louder than the 1 I got. all Chuckit balls... so, just this one I'm betting. but it flys good and the dog loves to chase it. he chews it a fair bit as well and the ball has not taken much damage from him (lab mix) or others that have had a go at it. I'll likely buy another at some point ... just wish it was a little louder when flying.

Blue ball, my dog likes blue.
Just a ball right? Evidently not! My dog won’t chase an orange chuck it ball or the glow in the dark ball- only the blue one 🤷🏼‍♀️
