Vent-Axia 479188 Lo-Carbon PoziDry Compact Pro Positive Input Ventilation (PIV)

The Vent-Axia 479188 Lo-Carbon PoziDry™ Compact Pro is a compact Positive Input Ventilation (PIV) unit designed specifically for properties without loft space, including flats and apartments.

Providing a simple and effective solution for reducing condensation and mould, the Compact Pro introduces fresh, filtered and tempered air into the property to improve indoor air quality and create a healthier living environment.

Its ultra-compact design, flexible installation options and quiet operation make it ideal for social housing refurbishment projects and residential applications where installation space is limited.

Compact & Flexible Installation

The Lo-Carbon PoziDry™ Compact Pro has been designed to fit into smaller spaces where traditional loft-mounted PIV systems are not suitable. Multiple inlet and outlet positions allow the unit to be installed in the most practical location within the property.

Fresh air is drawn into the unit through an external inlet and filtered before being gently supplied into the room through a discreet integrated grille. The grille can be rotated into eight different positions to ensure airflow is directed upwards, helping to reduce cold draughts.

Advanced Air Quality & Comfort

The system helps tackle condensation and mould by continuously supplying fresh, filtered air into the property, diluting moisture-laden indoor air and improving ventilation performance.

The integrated 300W heater tempers incoming air to improve occupant comfort during colder weather conditions.

Ultra-Low Noise & Efficient Performance

The precision engineered scroll and impeller assembly, combined with the anti-vibration EPP body construction, ensures exceptionally quiet operation and improved energy efficiency.

If the ambient temperature exceeds 27°C, the unit automatically switches off to prevent overheating. This temperature setting can be adjusted during installation if required.

Smart Sense™ Technology

Smart Sense™ technology records system usage and energy consumption to provide valuable operational data. The built-in three-digit lock feature prevents unauthorised tampering with settings once installed.

Easy Maintenance

The removable inner cartridge design allows for straightforward maintenance and servicing, while the washable filters help maintain long-term airflow performance and indoor air quality.

Not polyester! Thank you UA!
I never realized shopping for cotton socks in 2024 would be so difficult. Luckily I found these, and all the other Under Armour cotton socks and they are the best. I cannot wear polyester, and these only have like 1%. I didn't realize our cotton is being replaced by polyester, and I don't like it. Bath towels don't work anymore either... I need my cotton socks and towels, I love incandescent light bulbs, I'll always have a gas powered mower and leaf blower. Also butterfinger should've never their recipe. Just sayin...

Great sock for everyday
Size: Large, Color: Black/Gray (6 Pairs)
So these are awesome but they are slightly thinner than older versions, shorter too. Just FYI if you a long time UA customer. If you have never had their socks, I love them personally and only like one other brand better. They aren’t overly thick and they allow your feet to breath. I never have sweaty feet in these even in my warm boots. I also like that they don’t cut into my feet or get holes in the toes over long terms. The only reason I’ve thrown these out has been fraying near the ankle or someone (kids) thieving them.

LOVE THEM!!
Size: Small, Color: (001) Black / Black / Castlerock
LOVE! These socks are so comfortable! I wear a 5 in women's and a 3 in big kid shoes. The small fit me perfectly. I see where some say they run small but I can't say that was an issue for me. They are "snug" but thats what you want with a no show sock. I feel they have support vs the ones i used to buy at Walmart. They are very soft! I am actually buying more today and throwing my other ones in the trash!

So will not write down your foot
Size: Medium, Color: (001) Black / Black / Castlerock
I love these socks. They have a little bit of gel on the top of the heel for support in your tennis shoes and so your socks don’t write down. Very good quality.
