Top Marks for Classroom Ventilation: Introducing the Infinity® ClassFlo® CF350

21/08/2025

Our latest decentralised heat recovery unit for classrooms, the Infinity® ClassFlo® CF350, has now officially launched – allowing schools nationwide to immediately create healthier, quieter, and more efficient learning spaces.

Purpose-built for education settings, this unit combines high-performance engineering with intelligent control to deliver cleaner air, lower energy bills, and quieter learning environments.

Whether your school is planning maintenance during the next half- or full-term break, or wants to upgrade as soon as possible, the CF350 is available now and primed to make an instant difference.

The benefits of the Infinity^® ClassFlo^® CF350

From mainstream classrooms to special educational needs (SEN) environments, the CF350 is tailored to meet the complex needs of modern education settings.

It meets the latest standards for school ventilation and building performance, including BB101, BB93, Approved Document F, and Approved Document L. So excellent indoor air quality, thermal comfort, and sustainability are all guaranteed.

This system provides 100% fresh, filtered air with no recirculation or mixing, helping keep classroom CO₂ levels below the recommended daily average of 1,000 ppm. For pupils, this translates into better concentration, less fatigue, and more productive learning environments.

Understanding the full tech specs

The CF350 is a high efficiency counterflow heat exchanger available in above ceiling and below ceiling configurations with either left- or right-hand access. Installation is straightforward, with top and bottom access for maintenance and most sensors housed within the unit itself to reduce additional setup costs.

Once installed, intelligent controls make operation a breeze. Remote access via Bluetooth or NFC means no specialist tools are required. The unit also integrates with building management systems via Modbus, with BACnet compatibility available on request.

Once in place and fully operational, each CF350 unit:

• Recovers up to 88% of heat, reducing the need for additional heating or cooling
• Uses up to 52% less classroom energy compared to low-efficiency or hybrid systems
• Delivers up to 78% greater energy efficiency
• Offers full heat recovery with consistent temperatures and ventilation, even during winter and summer peaks
• Meets the 30 dB(A) requirement for SEN sensory spaces, vital for pupils with auditory sensitivities or hearing impairments.
• Ensures noise stays low via a double-skinned construction with acoustic insulation
• Supports respiratory health and school attendance with high-efficiency F7 and M5 filters removing pollutants, allergens and fine particles from the air
• Optimises comfort with four seasonal operating modes, including heat exchange and free cooling

The CF350: ready when you are

Whether you’re upgrading a single classroom or planning a site-wide rollout, the CF350 can be installed with minimal disruption.

If your school also needs ventilation solutions for kitchens, toilets, shower areas or communal spaces, Air Vent Technology has a full range of systems to support your project.
