XFQT-60-01S Ion Catalytic – Fresh Air Purifier
The Legom XFQT-60-01S Energy-Saving Duct Fresh Air Purifier is a through-the-wall fresh air unit that combines ion catalytic purification with an energy-saving design for continuous supply of clean outdoor air into residential and commercial spaces. Using ion catalytic technology, the XFQT-60-01S removes PM2.5, dust, pollen, smoke, formaldehyde, benzene-series pollutants, and airborne viruses and bacteria while delivering a supply air volume of 60m³/h at only 12W of power consumption.
Installed through the wall rather than occupying floor space, the XFQT-60-01S avoids the secondary pollution risk of traditional duct systems — where dust accumulation and moisture in pipelines provide breeding grounds for mold and bacteria — by delivering purified fresh air directly without passing through shared ductwork. A related model, the XFQT-65-01S Negative Ion Heat Exchange Type, adds heat exchange recovery to reduce air conditioning load while maintaining the same through-the-wall installation and IP22 protection rating.
Key Benefits
- Ion catalytic purification technology – Removes PM2.5, dust, pollen, smoke, formaldehyde, benzene-series decoration pollutants, and allergens from incoming outdoor air before delivery into the room, improving respiratory health without chemical consumables
- Sterilization and disinfection – Ion catalytic action effectively kills airborne viruses and bacteria in the air stream, reducing pathogen load in the indoor environment
- Energy-efficient operation at 12W – Significantly lower power consumption than traditional fresh air purification equipment, reducing operating costs during continuous 24-hour ventilation
- Eliminates dirty duct secondary pollution – Through-the-wall direct installation avoids dust accumulation and bacterial growth in traditional pipelines, eliminating the risk of contaminated air from aging or uncleaned ductwork
- Heat exchange energy recovery (XFQT-65-01S) – The heat exchange variant recovers energy from exhaust air while introducing outdoor fresh air, reducing the temperature differential and lowering air conditioning load during summer and winter
- Quiet operation at 38dB(A) – Low noise level does not interfere with sleep, conversation, or work in the installed room
- Through-the-wall installation – No floor space required; core unit is installed directly through the exterior wall with a 160mm pipe diameter opening, suitable for most residential wall constructions
- IP22 protection – Rated for indoor installation with protection against solid objects and dripping water
- OEM and ODM customization available – Contact Legom for customized specifications, branding, or system integration requirements

Application & Use Cases
- Residential bedrooms and living rooms – Continuous 24-hour fresh air supply at low noise (38–39 dB(A)) makes the XFQT-60-01S suitable for sleeping areas and primary living spaces where air quality and quiet operation are both priorities
- Newly renovated spaces with decoration pollutants – Ion catalytic technology targets formaldehyde and benzene-series substances released by new paint, adhesives, and flooring materials during the off-gassing period after renovation
- High-rise apartments and urban environments – Where opening windows for natural ventilation introduces traffic pollution, PM2.5, and urban particulates, the XFQT-60-01S filters outdoor air before delivery into the room
- Offices and work-from-home environments – Quiet operation below 40 dB(A) avoids distraction during calls and focused work while maintaining CO2 dilution and fresh air supply
- Spaces requiring virus and bacteria reduction – The ion catalytic sterilization function reduces airborne pathogen load, making it relevant for medical waiting areas, clinics, and high-occupancy rooms
- Energy-conscious HVAC integration (XFQT-65-01S) – The heat exchange variant is suited for climates with significant heating or cooling loads, where recovering energy from exhaust air meaningfully reduces the operational cost of maintaining fresh air supply
Installation Notes
- The XFQT-60-01S is installed through the exterior wall using a core drill to create a 160mm diameter hole. Ensure the wall thickness and structure are compatible with this installation method before specifying
- Plan the installation location to minimize the length and bends in the wall passage while ensuring the indoor unit is accessible for periodic cleaning and maintenance
- The unit does not occupy floor space — it is mounted flush with or recessed into the interior wall surface. Verify adequate interior clearance around the unit for airflow and access
- Connect to a 220VAC 50Hz power supply with an independent circuit breaker or switch for safe isolation during maintenance
- Seal around the wall sleeve with appropriate weatherproof sealant to prevent moisture ingress and drafts around the installation point
- The outdoor face of the unit should be protected from direct rain exposure. IP22 provides protection against dripping water only — verify that the installation location does not expose the unit to driving rain or water spray
- Follow all local building regulations regarding wall penetrations and ventilation installations
Frequently Asked Questions
What is the difference between the XFQT-60-01S and XFQT-65-01S?
Both models use through-the-wall installation with a 160mm pipe diameter and IP22 protection. The XFQT-60-01S uses ion catalytic purification technology and consumes 12W. The XFQT-65-01S adds a heat exchange module that recovers energy from the exhaust air stream while introducing fresh outdoor air, reducing the thermal load on the room’s heating or cooling system. The heat exchange model consumes only 10W and delivers a slightly higher supply air volume of 65m³/h versus 60m³/h for the catalytic model, but weighs less at 3.2kg versus 4.0kg. Choose the XFQT-65-01S when energy recovery and reduced air conditioning load are priorities; choose the XFQT-60-01S when maximum ion catalytic purification performance is the primary requirement.
How does ion catalytic purification differ from HEPA filtration?
HEPA filtration physically captures particles by passing air through a dense filter medium, which requires regular replacement as the filter becomes loaded with particles. Ion catalytic technology uses charged ions to neutralize and decompose pollutants — including gaseous pollutants like formaldehyde and benzene that HEPA filters cannot capture — without a consumable filter element that needs periodic replacement. The ion catalytic approach also enables sterilization of airborne viruses and bacteria, which HEPA filtration alone cannot achieve. The tradeoff is that ion catalytic systems produce trace levels of ozone as a byproduct of the ionization process, though well-designed units keep this within safe indoor air quality limits.
Does the unit require ongoing filter replacement or maintenance?
The ion catalytic technology does not use consumable filter media requiring periodic replacement, reducing long-term maintenance costs compared to HEPA-based systems. Periodic cleaning of the unit’s air intake and outlet surfaces is recommended to prevent dust accumulation that could reduce airflow. Refer to the user manual for the recommended cleaning schedule and procedure specific to your installation environment.
What room size is the XFQT-60-01S suitable for?
With a CADR of 57m³/h and a supply air volume of 60m³/h, the XFQT-60-01S is suited for rooms of approximately 15 to 25 square metres depending on ceiling height and ventilation requirements. For larger rooms or open-plan spaces, multiple units or a higher-capacity model may be required. Contact the Legom team for sizing guidance specific to your project.
Can the unit be installed in an apartment without access to the exterior wall?
The XFQT-60-01S requires a through-the-wall installation with access to the exterior wall surface for the outdoor air intake. It is not suitable for interior rooms without an exterior wall or for buildings where wall penetrations are not permitted. For such spaces, a different ventilation solution would be required. Contact Legom to discuss alternative product options for your specific installation constraints.
