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.

  • 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.

Indestructible dog toy
Color: 1PC-Beef-Red, Color: 1PC-Beef-Red
I have an 85 lb Pitbull and he loves to chew on those kind of hard bones but the meat flavor and scent is only in the middle the knobs on the end are just plain nylon and yes it is taking him a long time to get through them but little white fibers keep coming off I find them on the couch and he nibbles and tries to eat it so I believe he's eating the nylon and still has yet to get to where the beef flavor is in the center he doesn't chew from the middle he goes from the end all of his other chew toys he has he has demolished this one not so much I only gave four stars because my dog doesn't like it so much it is a very good sturdy toy though and has a good beefy smell. And a fair price.

Not completely indestructible but definitely long-lasting with plastic bits everywhere
Color: 1PC-Beef-Red
It's destructible it just takes a long time and tons of tiny little plastic pieces everywhere and even in your dog's stomach would not recommend due to wear and tear on dog's teeth and the plastic chips off.

Great Product!!!
Color: 1PC-Beef-Red
This is the first toy my dog has not demolished. I need to buy more just like it just in case something happens to this one. It's worth every bit of the money I spent on it.
