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.

Just lovely
Size: 8.5" x 5.8" x 1.9", Color: Orange
Purchased this several months ago and liked it, but I had received so many complements on this tray since then I had to submit this review. The tray is sturdy and put together well, and the size is exactly what was given before purchase.

A Stylish and Functional Addition to My Décor!
Color: Gray 1 Pack, Size: 8" x 8" x 1.8", Color: Gray 1 Pack, Size: 8" x 8" x 1.8"
I recently purchased the ZHEM Valet Tray for Men in Dark Gray, and I couldn't be happier with this product. It's become an indispensable part of my daily routine and home décor. The design and craftsmanship of this tray are outstanding. The dark gray color is elegant and complements my furniture perfectly. It's not just a valet tray; it's also a decorative piece that adds a touch of sophistication to my nightstand and dresser. The size (8x8x1.75 inches) is ideal for holding my daily essentials like my watch, perfume, keys, and even napkins. I appreciate the versatility - it serves as a decorative piece, an organizer, and a functional tray all in one! The quality is top-notch, and it feels sturdy and well-made. It's also easy to clean, which is a big plus. Overall, the Tray has exceeded my expectations. It's a stylish and functional addition to my décor, and I highly recommend it to anyone looking for a versatile and attractive tray for their home. Five stars! ⭐⭐⭐⭐⭐

Super cute landing space for keys
Color: White 1 Pack, Size: 8" x 8" x 1.8", Color: White 1 Pack, Size: 8" x 8" x 1.8"
I always have trouble finding my keys and so it’s been very helpful to have a dedicated spot to easily throw them in when I get home. At first I thought it would be too big but it’s the perfect size for two wallets and keys, and it’s good quality albeit a bit expensive. The gold isn’t too shiny either, it’s a nice touch and it really reduces the look of clutter on your surfaces and helps it look more organized. It also doesn’t slip around.
